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 a failing roller bearing include increased noise, such as humming or grinding, and noticeable vibration during operation. If left unaddressed, the bearing can seize, leading to severe damage to surrounding components and potential loss of power transmission.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installation to prevent contamination. Avoid using excessive force or improper tools when pressing the bearing into its seat, as this can cause damage.

Service Note

Inspect the adjacent shaft and housing for any signs of wear or scoring when replacing this roller bearing.
