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 indications of failure include audible grinding or humming sounds and increased vibration from the equipment. If ignored, the bearing can seize, potentially causing damage to shafts and housings, and leading to a loss of function in the affected system. Failure to replace this bearing can result in significant unscheduled downtime and extensive repair costs.

Installation Tip

Before installing, ensure the bearing seat in the housing is perfectly clean and free from any burrs or imperfections. Never use a hammer or pry bar to install the bearing; use a proper press or driver to apply force evenly to the outer race.

Service Note

Inspect the shaft for scoring or wear, and check any associated seals or gaskets for signs of leakage or damage.
