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

Initial signs of failure may include a noticeable increase in noise, such as humming or grinding, and potential vibration during operation. If left unaddressed, the bearing can seize, leading to damage of the shaft and housing, and potentially immobilizing the component it supports. Continued operation risks significant mechanical failure and costly downtime.

Installation Tip

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

Service Note

Inspect the shaft and housing for any signs of wear, scoring, or contamination that could impact the new bearing's service life.
