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

The first indication of a failing bearing might be a subtle humming sound that intensifies with increased speed or load. If left unaddressed, this can escalate to a pronounced grinding noise and noticeable vibration, potentially impacting the machine's overall performance. Continued operation risks damage to associated components and unplanned downtime.

Installation Tip

Ensure the mounting surface is perfectly clean and free of any burrs or debris before installing the bearing. Press the bearing in squarely to prevent any misalignment that could lead to premature failure.

Service Note

When replacing this bearing, inspect the condition of the shaft and any associated seals for wear or damage.
