Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of failure may include a grinding noise from the undercarriage while the machine is in operation. If left unaddressed, the bearing can seize, leading to track slippage and potential damage to the track links and rollers. Continued operation with a failed bearing risks severe damage to the entire undercarriage assembly.

Installation Tip

Ensure the bearing housing is thoroughly cleaned of all old grease and debris before installation. Avoid forcing the bearing into place, as this can damage the races and compromise its seating.

Service Note

Inspect the adjacent seals and roller surfaces for any signs of wear or damage during bearing replacement.
