Slewing bearing, also known as slew ring bearing, is among the most vital constituents of an excavator. Large, heavy-duty equipment such as excavators and construction cranes rely upon slewing bearing to support heavy loads. Slewing bearings provide incredible power and versatility for heavy-duty construction equipment. Sometimes, due to mechanical fault or normal wear, the slewing bearing will stop working or stop performing as desired. Slewing bearing failure can severely hamper the productivity and operations of a business.
When to Replace Slewing Bearing on Excavator
Heavy-duty construction equipment such as excavators is built to last. As long as there is regular maintenance and they are working under ideal conditions, this equipment can last a lifetime. However, the internal components of the equipment are still subject to wear and tear and are bound to succumb to deterioration resulting from ordinary use. One of the most common causes of failure in an excavator is the slew ring bearing. There are many signs of problems when it comes to swing-bearing failure on excavators.
Here are some of the key indicators of slewing bearing failure to help you know when to replace the swing bearing on an excavator.
Metal particles or flakes in the lubricant
One of the most obvious clues of swing circle issues is the state of the lubricant. The presence of flakes, particles, or metals in the lubricant means there is some kind of wear taking place.
Increase in torque
A substantial increase in the turning torque could possibly be an indication of a problem. In most cases, it’s proof of unequal depreciation in the raceway. It could also be the result of inadequate lubrication. In an excavator, this problem can manifest through rocking or wobbling in the top construction particularly when the cultivating arm is outstretched with a load.
Increased clearance
Clearance or play is a key indicator of a failing slewing bearing. The swing circle is designed with a specific level of clearance. A dramatic increase in the quantity of clearance is a sign of wear in the raceways. Wear accelerates with the increase in clearance resulting in the overall stiffness of the entire system.
Excessive noise
Clicking, popping, or grinding noises from the swing bearing is an indication of wear in the raceway. The noise could also be the result of inadequate lubrication.
These are just a few of the most common indicators of failure in slewing bearings. Watching out for these signs will help you detect issues and know when to repair or replace the slewing bearing in your excavator. Detecting slewing bearing issues early can help businesses avoid catastrophic failure.
Slewing Bearing Replacement Options: OEM or Aftermarket
There comes a time when you have to replace a vital excavator part such as slewing bearing, there are a few options to consider. Typically, customers have two major types of replacement slewing bearings to choose from. You can go for the Original Equipment Manufacturer (OEM) parts or the aftermarket slew bearing replacements. So, which option is the best? Let’s start by explaining the difference between OEM and excavator replacement parts.
As the name suggests, OEM parts are manufactured by the same company as the component they are supposed to replace. OEM slewing bearings come with the promise of quality and longevity and often lives up to the hype. However, OEM parts tend to be significantly more expensive than other options and are only available in one type. Aftermarket excavator parts, on the other side, are manufactured by a third-party. They are reverse engineered to match OEM specifications.
Between OEM and aftermarket excavator parts, which is best for you? Well, both options have their unique advantages and disadvantages. OEM parts guarantee quality and durability, but they may be too expensive for some customers. Aftermarket parts are cheaper and more readily available. In terms of quality, well-made aftermarket excavator parts will match or even exceed their OEM counterparts at a fraction of the price.
