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 failure symptoms can include a low grinding sound or noticeable vibration from the affected component. If the bearing continues to degrade, it can lead to increased resistance, component binding, and potential overheating. Ignoring these symptoms can result in severe damage to the shaft and housing, leading to costly repairs.

Installation Tip

Verify that the bearing bore and shaft are perfectly clean and free from any debris or burrs before attempting installation. Never use a hammer to drive the bearing into its housing; use a proper press and driver set.

Service Note

Inspect the seals associated with this bearing for wear or damage, and check the lubrication system for proper function.
