Track Roller

Track Roller for Off-Road Machinery

A track roller, also named a bottom roller, support roller, or lower roller, is similar in design to a carrier roller. It is installed on the tracks or rails of machinery to evenly support the machine's weight and reduce friction with the ground. Different off-road machinery has varying functions, so the design of a bottom roller is different. For example, an excavator’s bottom roller often has a rear axle, while a dozer track roller features a larger running surface. To properly distribute the machine's weight and ensure efficient operation, FridayParts can help you choose the right roller.

FAQs

How many track rollers are typically on each side of off-road machinery undercarriages?

The number of track rollers on each side of the undercarriage varies depending on the type and use of the equipment. Small excavators typically have 3 to 5 bottom rollers per side, while medium-sized excavators and dozers usually have 5 to 7. Large machinery generally has 7 to 9 rollers per side, and wheeled machinery usually has 2 to 4.

Why is it necessary to clean and lubricate these support rollers?

Regular cleaning and lubrication prevent excessive friction that can lead to performance degradation of the support rollers. After long-term using, it will impact other undercarriage parts. So, it is essential to clean and lubricate.
