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 failure symptoms can include a grinding sound during operation or a noticeable increase in vibration. If the bearing continues to degrade, it can lead to component seizure, potentially damaging shafts and housings. Ignoring these symptoms risks significant mechanical failure and costly repairs.

Installation Tip

Thoroughly clean the bearing housing bore and the shaft surface before installation to prevent contamination. Avoid applying force to the bearing's outer race when pressing it onto a shaft; use appropriate tooling to apply force to the inner race.

Service Note

Inspect the associated shaft, housing, and any seals for wear or damage during the bearing replacement procedure.
