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 failure symptoms include audible humming or grinding sounds from the affected area. As the bearing degrades, these sounds will become more pronounced, accompanied by increased heat and potential binding. Ignoring these signs can lead to damage to the shaft or housing, requiring more extensive repairs.

Installation Tip

Ensure the bearing seat in the housing and the shaft are perfectly clean and free of burrs before installation. Never use a hammer or pry bar directly on the bearing races; use appropriate press tools.

Service Note

Inspect the surrounding seals and lubricant for signs of contamination or leakage when replacing this bearing.
