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 signs of failure may include a grinding noise during operation or increased heat from the affected area. If left unaddressed, the bearing can seize, leading to shaft damage and potential drivetrain component failure. This can result in unexpected equipment downtime and costly repairs.

Installation Tip

Ensure the bearing seat is thoroughly cleaned of all old lubricant and debris before installation. Avoid using excessive force or improper tools when pressing the bearing into its housing, as this can cause immediate damage.

Service Note

Inspect the shaft and housing for any signs of scoring or wear that could compromise the new bearing's service life.
