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 of a failing race and roller assembly include increased noise, such as humming or grinding, and a noticeable increase in vibration. If left unaddressed, the rollers or races can spall or seize, leading to restricted movement and potential damage to the shaft or housing.

Installation Tip

Ensure the bearing seat and shaft are perfectly clean and free from any imperfections before pressing the assembly into place. Use a proper press and alignment tool to avoid cocking the assembly.

Service Note

When replacing a race and roller assembly, inspect the bearing seals, shaft, and housing for any signs of wear, damage, or contamination.
