Excavator Swing Bearing – The Complete FAQ Guide
“Your excavator swing bearing is damaged. You’ll have to replace it with a new one.”
The above statement is one that most excavator owners dread the most. It is because they understand the importance of the excavator swing bearing and how replacing it is quite intimidating.
I’m not going to lie to you:
An excavator swing bearing is one of the vital components of your excavator. The excavator cannot function without it. In addition, it is linked with other key excavator components.
In this article, you are going to learn:
- What a swing bearing is in excavators
- How excavator swing bearings works
- Where and how to get the best excavator swing bearings that will offer you a long service life
Keep reading this guide to find out more.
1. What Is A Excavator Swing Bearing In An Excavator?
An excavator swing bearing in an excavator is a piece of heavy-duty equipment that helps your excavator have immense power when supporting heavy loads. An excavator swing bearing is also known as a slewing bearing or a turntable bearing.
Check this out:
An excavator swing bearing helps your excavator work effectively and efficiently without having to change its position. An excavator swing bearing connects your excavator’s undercarriage and the cabin. The excavator swing bearing can then carry loads without changing its undercarriage position.
An excavator swing bearing consists of two rings; an outer and inner ring. Both rings have holes drilled in them. The holes are strategically drilled to properly mount the device on your excavator during installation.
Depending on the make and model of your excavator, one of the two rings will be geared.
In other words:
Either the outer ring or the inner ring is geared. By now, you already know how valuable the excavator swing bearing is to excavators. You’ll also need to know how to take care of them. All of this information is clearly explained here.
Keep reading this guide to find out how to take care of your excavator swing bearing.
2. How Do You Check Excavator Swing Bearings On An Excavator?
Here’s the deal:
Once your excavator swing bearing fails, you’ll be unable to use your excavator. Some signs tell you when your excavator swing bearing is almost failing – or when it is completely damaged.
Here’s how you should check an excavator swing bearing on an excavator:
● Excavator Swing Bearing Lubricant
The first place you need to check is the level of lubricant. Is it at its optimum level? If not, it means that your excavator swing bearing leaks its lubricant, which in turn means that you need to check its seals. If the seals are damaged, replace them as soon as possible.
It’ll help lengthen the service life of your excavator swing bearing by preventing the intrusion of contaminants like water or even dirt.
Also, you’ll need to exercise your hearing power. Listen for clicks, pops, or grinding noises. If these noises are present, it then means that your excavator swing bearing is under-lubricated. You’ll need to lubricate it adequately.
The clicking, grinding, and popping noises could also mean that your raceway is completely worn out.
After checking the level of your excavator swing bearing’s lubricant, consider checking the lubricant itself. Does it have metal flakes? If the answer is yes, it means that there is excessive wearing-out of the excavator swing bearing’s raceway.
● Excavator Swing Bearing Movement/Play
The second thing you need to check out in your swing bearing on your excavator is the raceway’s play. Does it move too much? If so, you should know that your excavator swing bearing is worn out excessively.
You’ll need to be careful of the performance of your machine once you discover that there is too much play in the excavator swing bearing. You may get a rocky or wobbly motion on your excavator if your excavator turns with a lot of torque, touching an uneven raceway.
● Excavator’s Behavior
You’ll need to monitor your excavator’s behavior: There are two behaviors you need to check out:
When your excavator’s cabin resists moving/swinging because of the swing bearing, it’ll probably be because there is an issue with the swing bearing.
Contrary to that, when the cabin swings past the desired place, you should also check out the health condition of your excavator swing bearing.
Checking out your swing bearing on your excavator goes beyond physically looking at it. It involves checking its lubricant as well as monitoring its behavior.
You’ll need to keep your eyes and ears open and keen to prevent any premature excavator swing bearing failure. It will help you avoid being caught unaware.
You can always contact us for more information about your excavator swing bearing. We’ll be happy to help you out.
3. How Does An Excavator’s Swing Bearing Work?
An excavator’s swing bearing works by allowing the excavator to move without changing position. In other words, it slews the excavator.
It has two rows of rolling elements. It can turn 360 degrees. It can do so because of its large swing bearing that connects the undercarriage and the cabin. The swing bearing can handle all three load spectrum’s complexities. These three complexities are thrust, radial, and tilt.
Excavator Swing bearings are ideal because they provide a lot of working torque. It doesn’t produce noise also, meaning it’s effective and efficient.

4. What Are The Common Excavator Swing Bearing Problems?
Your excavator swing bearing is specifically manufactured for your excavator’s particular make and/or model. Some factors damage your swing bearing prematurely. Some of these factors damage your swing bearing completely – beyond repair.
However, there are some assumptions that we must first consider:
- Your excavator swing bearing was manufactured according to OEM standards, and it is the best of the best.
- The excavator swing bearing’s load calculations are correctly selected.
- The excavator swing bearing was correctly installed.
- Over time, you have been keen on the excavator swing bearing’s maintenance, e.g., lubrication using the correct type and amount of grease, etc.
- Use high-quality seals for your excavator swing bearing.
Now, having those assumptions in mind, here are some common problems that you’ll eventually face:
Firstly, all bearings wear out over time. Wear and tear come about because of both balls and rollers’ constant movement in the raceways – even with sufficient high-quality grease. Uneven load distribution causes quicker wear and tear.
The second common problem that you’ll most likely face is pitting and chipping. Heavy loads bring about pitting and chipping on your excavator swing bearing’s roller elements.
Here’s how pitting happens:
When your excavator swing bearing works (rotates), the rolling elements also roll cyclically in the raceways. This common failure happened when your excavator swing bearing underwent incorrect heat induction. Whenever pitting and chipping happens, you’ll need to replace your swing bearing with a new one as soon as possible.
At times, fatigue may occur because of improper internal lubrication. When your excavator swing bearing is improperly lubricated internally, the raceway will eventually face spalling. Spalling then results in premature wearing out of the races and causes corrosion in the long run.
The third bearing issue that you’ll most likely face in the life service of your excavator swing bearing is slackness. Slack is brought about by abnormal gaps between the excavator swing bearing’s rolling elements.
The improper foundational structure frequently causes slack during mounting.
The above-mentioned common failures are just the frequently observed ones. It is vital to constantly monitor the health of your excavator swing bearing to avoid unnecessary costs and repairs. It’ll also help you prevent being caught unaware.

6. How Can I Repair A Excavator Swing Bearing?
Repairing an excavator swing bearing has one benefit over completely replacing it – cost-effective. Repairs are less expensive than replacement. However, these repairs do not guarantee you that your problem will be solved.
Now, repairing an excavator swing bearing involves different processes that make the swing bearing look and work as if it were new.
Check it out:
- Groove grinding – When your excavator swing bearing’s grooves are not as deep as they were before, you’ll need to grind them anew. Groove grinding is important, as grooves degrade during usage over time.
After grinding your excavator swing bearing’s grooves, remember to polish them adequately to remove burrs. Burrs are unwanted sharp edges that are present on the surfaces of your modified grooves. They are dangerous as they can cut you. They even go further to damaging gears.
- Turning Races – Turning is a process that involves rationally removing unwanted parts and thus forming new ones using a turning machine. When repairing your excavator swing bearing, its races can be turned to make them as effective as they were before.
- Heat Induction of Races – Once the races are turned, they are then heat-induced. It helps them become hardy, thus, reliable.
The above process is a complete overhaul of your excavator swing bearing. It is done professionally. Once complete, you’ll need to check if everything runs as it should.
You’ll, however, find out that it’s not all the time that your excavator swing bearing will require a complete overhaul. At times, it’ll simply require replacement of seals, oil change, etc. KS offers all these services.
Our goal is to ensure that our company becomes a one-stop shop for all excavator parts. You can reach out to us today through our website’s contact us page. We’ll also be happy if you decided to check out our entire website to learn more about us.
7. What Is The Difference Between A Swing Arm & A Swing Bearing?
A swing and a swing bearing are two completely different parts of an excavator.
Check this out:
A swing arm, as the name suggests, works like an arm. The arm supports the bucket. It is in turn supported by the excavator’s boom, as depicted in the image below:
On the other hand, a swing bearing is a piece of heavy-duty equipment that helps your excavator have immense power when supporting heavy loads. An excavator swing bearing is also known as a slewing bearing or a turntable bearing.
The swing bearing allows the excavator to work effectively and efficiently without changing its position.
In other words:
It helps it slew. It can rotate 360 degrees without changing position.
8. How Can I Know If My Excavator Swing Bearing Is Bad?
You’ll probably know when your excavator swing bearing is damaged because of how the excavator functions and behaves.
Here’s how your excavator is expected to behave once its swing bearing gets damaged:
First, you’ll realize that the excavator resists slewing. There will be difficulty in slewing, which shows you a massive problem with your excavator swing bearing. Consider replacing it with a new one.
The second sign is that your excavator swing bearing will not work efficiently or effectively. It’ll not slew to the point you want – it’ll go past that point.
The third way that you’ll know your excavator swing bearing is damaged is through its lubricant level. If its lubricant level keeps dropping, then there is an issue with your excavator swing bearing’s seals. Damaged seals can cause complete damage to your swing bearing. Consider replacing them as soon as possible.
Also, check your lubricant’s surfaces. Are there visible metal flakes? If yes, you should know that your excavator swing bearing faces much wear and tear in the raceways.
You can always contact KS if you are faced with indecision or doubts about something. We’ll be glad to hear from you and help you out.
9. Why Does My Excavator Swing Bearing Produce Noise?
Your excavator swing bearing may occasionally produce noise. Noise can act as an indicator that your swing bearing is damaged. It could also be due to environmental factors. This means that you should be keen once you hear noise coming from your swing bearing:
Here’s why your excavator swing bearing produces noise:
Your swing bearing could produce noise because it has foreign matter on its surface. This foreign matter includes dust, sand, etc. When the excavator swing bearing has foreign matter on its surface, you’ll probably feel a vibration.
You can get rid of this type of noise by enhancing your excavator swing bearing cleaning methods. Focus mostly on the bearing itself and the shaft during cleaning. It’ll require you to disassemble the excavator’s cabin from the undercarriage.
The second reason why your swing bearing produces noise is that there are either cracks or indents or rusty parts on its surfaces. When this happens, you’ll also feel some vibrations. The best way to prevent this problem from even beginning is by correctly installing the excavator swing bearing.
Also, the manufacturer should ensure that the swing bearing is rust-proof after manufacturing it.
The third reason why you’ll probably hear noise from your excavator swing bearing is because of lubrication issues. The lubrication process requires you to use the correct amount and, most importantly, the correct type of lubricant.
Do not over-lubricate your excavator swing bearing.
Apart from constantly checking the excavator swing bearing, consider also checking other excavator components that could contribute to this noise.
10. Why Does My Excavator Swing Bearing Leak Grease?
Your excavator swing bearing leaks grease because there are only two possible reasons.
Check them out:
The first reason is probably that your swing bearing seals are damaged. Damaged seals will always leak oil, and the worst part of it all is that they can completely damage your excavator swing bearing.
You should replace the damaged seals with new ones from a reputable company. Not only will they help you save your swing bearing, but they also offer you a longer service life compared to excavator parts from other companies.
The second reason why your excavator swing bearing leaks grease is because you over-lubricate it. Over-lubrication will force grease out of your swing bearing’s seals – even if they are new or in good condition.
Over-lubrication is highly discouraged by KS because it causes your excavator to overheat when working. It also becomes ineffective and inefficient.
Consider using the correct amount specified by your excavator’s manufacturer. More importantly, consider using lubricants from world-class lubricant manufacturing companies.
Here’s the deal:
Once you find out that your excavator’s swing bearing is leaking grease, consider contacting a professional company first. Do not hurry to replace your swing bearing’s seals, thinking that they are bad. Contacting a professional company will guide you in understanding the issue and diagnosing the swing bearing correctly.
11. What Is The Process Of Replacing A Bad Swing Bearing For My Excavator?
Replacing a faulty excavator swing bearing is not easy. It requires focus, patience, and hard work to achieve it. Now, replacing a bad swing bearing requires you to know first how to disassemble your excavator’s cabin from the undercarriage. It also requires you to know how to install a new swing bearing.
To disassemble and remove a bad swing bearing, consider watching this short video that illustrates how to do it. The video will also show you how to install another swing bearing.
Not all excavators are the same. They vary depending on their make, model, and size. This difference also means that not all excavator swing bearings are the same. They’ll vary. You’ll therefore need to know your excavator’s make and model to get the right swing bearing.
You can then contact a reputable company to help you out with a new swing bearing and a guide on installing it properly.

13. How Can I Extend The Life Of My Swing Bearing Gear For My Excavator?
The only way to extend the lifespan of your excavator swing bearing is to maintain it properly.
You may be wondering to yourself:
“How can I maintain my swing bearing?”
- Lubrication – You need to lubricate your swing bearing to lengthen its service life. Lubrication also makes your swing bearing work effectively and efficiently.
Now, you need to remember that lubricating your excavator swing bearing needs to be done correctly. You’ll need to use the correct amount and type of lubricant. When adding grease, remember to rotate the swing bearing to ensure that the grease reaches all parts of the raceway.
- Bolts – You’ll need to check your bolts frequently as a routine maintenance procedure. You’ll need to check them as frequently as possible, depending on how severe your swing bearing gets used.
You’ll need to ensure that bolting gets torqued to the correct degree. Overdoing it will make it inefficient. You should also be careful with how you tighten your bolts during mounting.
Check out how you should tighten your bolts during installation:
- Seals – You’ll need to be extremely careful with your swing-bearing seals. They can make or break your swing bearing. How?
Excavator Swing bearings rely heavily on grease to reduce friction and prevent corrosion as they work. When you have damaged seals, your grease will leak. Faulty seals also allow the intrusion of contaminants like water and dirt. These contaminants corrode your swing bearing’s raceways.
In today’s world, part manufacturers struggle to become cost-efficient, which can compromise the quality of manufactured parts. That’s why you’ll need to contact a reputable company with a proven track record to help you out with your excavator parts.
14. How Can I Lubricate My Swing Bearing For My Excavator?
Lubrication is an important aspect in maintaining your swing bearing and increasing its lifespan. Now, there are mistakes that you should avoid when lubricating your swing bearings.
Check them out:
- Improper lubrication frequency – Some people have a common myth that you should lubricate your swing bearing annually. However, that is not true. You need to lubricate your excavator swing bearing according to your manufacturer’s specification.
- Use of wrong lubricants – Using wrong lubricants is yet a mistake many people use. All lubricants do the same job, but not all lubricants are the same. You need to be careful with the type of lubricant you decide to use.
- Over lubrication – Do not over lubricate your swing bearings. Many people fall for this mistake because they think that once they overlubricate their bearings, there will be no need to lubricate them again soon.
You should not over-lubricate your excavator swing bearing to the point that it starts purging from the bearing’s seals. When you overlubricate your swing bearing, the excavator will start heating up excessively, and it will become ineffective. It, therefore, renders the excavator inefficient.
- Do not add grease whenever your swing bearing makes noise.
It is true that:
Adding grease will stop the noise. However, it’s not all the time that adding grease helps solve the situation. Adding grease will temporarily save the problem. You’ll, however, need to get a permanent solution as fast as possible.
After avoiding these four common mistakes that most people make, you’ll also need to look out for the following red flags. They warn you of your swing bearing problems:
- Noises – When your excavator swing bearing starts making grinding or clicking or popping noises, know that there is a problem. That noise should notify you that your swing bearing’s raceways are worn out.
You can check your grease to see if you’ll find metal flakes. If you find them, know that your raceways are worn out. It could also mean that your excavator swing bearing has a loose bolt.
- Bearing Movement Play – You need to check out your swing bearing’s play. You may get a rocky or wobbly motion on your excavator if your excavator turns with a lot of torque, touching an uneven raceway.
- Excavator’s behavior – You need to look out for your excavator’s behavior. If your excavator strains to slew, know that your raceways are completely worn out. Also, if your excavator over-slews, you should also know that the raceways are worn out.
There may be other signs that your excavator swing bearing may show. However, these signs that are outlined here are the common ones that frequently occur.
15. What Lubricant Should I Use For My Swing Bearing For My Excavator?
As stated earlier, all lubricants perform the same task, but not all lubricants are the same. There are some good, leading lubricants for your swing bearing.
