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 failure may manifest as a subtle humming or grinding noise during operation, particularly when the affected component is under load. If ignored, the noise will intensify, and excessive heat may build up, potentially leading to component seizure. Continued operation risks damage to the shaft and housing, leading to costly repairs.

Installation Tip

Thoroughly clean the bearing bore and shaft before installation to prevent contamination. Avoid hammering or forcing the bearing into place; use appropriate press tools for a smooth, even fit.

Service Note

Inspect the shaft and housing for any signs of wear or damage, and check associated seals for integrity.
