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 indications of failure include unusual noises such as grinding or humming, and increased vibration during operation. If left unaddressed, the bearing can seize, potentially damaging the shaft and housing, leading to significant downtime. Continued use risks compromising the integrity of the entire assembly.

Installation Tip

Ensure the mating surfaces of the shaft and housing are clean and free from burrs or debris. Do not apply excessive force during installation, as this can damage the bearing's internal components.

Service Note

Inspect the shaft and housing for any signs of wear, scoring, or contamination before installing the new bearing.
