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 failure may include increased noise, such as humming or grinding, during operation. If left unaddressed, the bearing can seize, leading to significant operational resistance and potential damage to the supported component. Continued use risks compromising the integrity of the entire assembly.

Installation Tip

Ensure the bearing seat in the housing is perfectly clean and free from any burrs or old lubricant. Avoid using a hammer to install the bearing; use a proper press or driver to apply force evenly to the outer race.

Service Note

Inspect the shaft and housing for any signs of wear, pitting, or contamination that may have contributed to the bearing's failure.
