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 is often an audible noise, such as a hum or grind, and potentially increased heat around the component. If left unaddressed, the bearing can seize, causing damage to the shaft and surrounding parts, leading to a loss of function in the affected system. This can result in significant operational disruption and costly repairs.

Installation Tip

Before installation, ensure the bearing is properly lubricated with the recommended grease and that the shaft and housing surfaces are clean and free of imperfections. Avoid applying force to the outer race when pressing the bearing onto a shaft, or to the inner race when pressing it into a housing.

Service Note

Inspect the shaft or bore for wear, and check any associated seals for signs of leakage or damage.
