This bottom roller is a crucial component of the undercarriage system, designed to support the weight of the excavator and guide the track chain. It is manufactured to meet stringent quality standards, ensuring superior durability and performance compared to worn or damaged rollers that exhibit excessive play or uneven wear. Symptoms of a failing bottom roller include increased track noise, vibration, and potential track derailment.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing bottom roller will initially produce a grinding noise as it rotates, accompanied by increased vibration felt through the machine's chassis. If left unaddressed, the roller can seize, leading to track damage and potential derailment, compromising operational stability.
Ensure the track frame is clean and free of debris before installation to prevent premature wear. Avoid overtightening the mounting bolts, as this can damage the roller's bearing seals.
Inspect the track chain, idlers, and sprockets for wear and damage when replacing bottom rollers.
