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 often manifest as a rough grinding sound or noticeable play in the rotating component. If left unaddressed, the wear will accelerate, leading to increased friction, heat generation, and potential seizure of the shaft. Continued operation risks severe damage to the shaft and housing, necessitating more extensive and costly repairs.

Installation Tip

Ensure the bearing surfaces and the shaft are meticulously clean and free from any contaminants before assembly. Never use a hammer or pry bar to install bearings; always use a proper press or driver to ensure even seating.

Service Note

Inspect the shaft for any signs of brinelling or scoring, and check the lubricant for metal particles indicating excessive wear.
