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 indicators of failure include a noticeable looseness or play in the steering or drive mechanism, accompanied by clunking or grinding sounds during operation. If the bearing fails completely, it can lead to loss of control or component seizure, potentially causing significant damage to related parts. This can result in unexpected downtime and safety concerns.

Installation Tip

Ensure the mounting surface and shaft are perfectly clean and free from any burrs or imperfections before installing the new bearing. Avoid applying heat directly to the bearing itself; use a suitable press or driver.

Service Note

Inspect the surrounding seals and shaft for any signs of wear or damage when replacing this bearing.
