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 signs include a low humming or growling sound that becomes more pronounced under load. This can escalate to noticeable vibration and increased operating temperatures. Continued use risks severe damage to the shaft or housing, potentially leading to system failure.

Installation Tip

Ensure the bearing bore and shaft are perfectly clean and free from any burrs or debris before installation. Never use a hammer to drive the bearing into place; use a proper press or driver tool.

Service Note

Inspect adjacent seals, shaft surfaces, and the lubrication system for any signs of wear or contamination when replacing this bearing.
