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 symptoms of failure may include audible grinding or humming noises and increased vibration from the component. If ignored, the bearing can seize, leading to restricted movement or complete stoppage of the affected system. This can result in significant operational downtime and potential damage to related components.

Installation Tip

Ensure the bearing bore and shaft are meticulously cleaned and free of any old lubricant or debris before installation. Avoid applying excessive force or using improper tools, which can damage the bearing races and compromise its performance.

Service Note

Inspect the shaft and housing for any signs of wear, scoring, or contamination, and ensure the mounting area is clean before installing the new bearing.
