Excavator Roller – The Definitive FAQ Guide

This FAQ guide can help you with all your questions about excavator rollers. From rollers to their undercarriage accessories, all the parts are explained, and maintenance tips are provided.

Excavator rollers are an integral part of excavators. Although it is considered one of the simplest components of the machine, this component can simultaneously affect several parts’ functioning.

1. What is an excavator roller?

An excavator roller is a casting fitted to the undercarriage of most mobile excavators. It sits between the track frames and supports the tracks during digging. Via the sprockets, it transmits the tractive force from the engine through the drive train to the tracks.

This is a core part of an excavator, and many different types of rollers are used according to the machine’s weight capacity. The roller and sprocket combination works well because the small mover can transmit torque more efficiently through the roller instead of just bending and flexing the tracks.

It supports the entire weight of the machine and distributes this weight evenly to ensure a steady balance. To reduce friction and wear, ball bearings and specialized hardwearing rubbers are used to design this essential spare part for an excavator.

2. What is included in the excavator roller assembly?
