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

A failing roller assembly may first present as a grinding or squealing noise from the undercarriage. This can escalate to excessive vibration transmitted to the operator's station and uneven track wear. If left unaddressed, it can lead to track derailment or damage to adjacent undercarriage components.

Installation Tip

Thoroughly clean the mounting surfaces and bolt threads to ensure a secure and proper fit. Do not reuse old mounting hardware, as it may be stretched or damaged.

Service Note

Inspect the track chain, idlers, and final drive seals for wear or damage when replacing roller assemblies.
