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

A failing bearing will typically first present as increased noise, such as whining or grinding, from the affected hydraulic component or rotating assembly. This can progress to noticeable vibration and a reduction in the smooth operation or responsiveness of the equipment. If left unaddressed, bearing failure can lead to severe damage to shafts, seals, and housing, causing significant hydraulic system malfunction and extensive downtime.

Installation Tip

Ensure the housing and shaft surfaces are meticulously clean and free of any debris or old lubricant before installing the new bearing. Never use excessive force or impact tools directly on the bearing during installation, as this can damage the bearing races or cage.

Service Note

When replacing this bearing, inspect the associated seals, shafts, and housing for any signs of wear or damage that may have contributed to the failure.
