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

Early indications of failure include audible grinding or whining noises from the affected component, or a noticeable increase in operating temperature. If the issue persists, it can lead to excessive play, component seizure, and potential damage to adjacent parts. Continued operation risks severe wear on shafts and housings.

Installation Tip

Ensure the mounting surface and shaft are perfectly clean and free of burrs before attempting installation. Never use a hammer to drive the bearing into place; use an appropriate press or driver.

Service Note

Inspect the adjacent seals, shaft, and housing for any signs of wear or damage, and ensure proper lubrication is present.
