The list above is for reference. It is crucial to verify the OEM part number or roller dimensions.
Working on track undercarriages is extremely dangerous. Ensure the machine is on stable ground. Track tension must be released before service. The machine must be securely supported on certified stands. Never rely solely on the machine's own hydraulics.
Track rollers (bottom rollers) transfer the entire weight of the machine to the track chains and the ground. They are responsible for guiding the chain along the track frame and are subjected to constant high-impact loads and abrasion. Failure of one roller overloads the others and accelerates wear of the entire undercarriage.

A top roller (carrier roller) is located on top of the track frame and supports the weight of the returning, sagging section of the track. A bottom roller (track roller), like this one, is on the bottom and transfers the entire machine's weight to the track on the ground.
2. Is this roller maintenance-free?Yes. This roller is factory-filled with oil and equipped with durable, heavy-duty seals that provide lubrication for its entire service life. It does not require regular greasing.
3. My roller is seized. Do I have to replace it?Yes, absolutely. A seized (non-rotating) roller acts as a brake on the track chain. This causes rapid, abrasive wear on both the roller (creating "flat spots") and the track links, leading to a very fast and expensive failure of the entire undercarriage.
