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 symptoms of failure may include audible rumbling or grinding noises and increased vibration transmitted through the machine. If left unaddressed, the bearing can seize, potentially causing catastrophic damage to the shaft and surrounding drivetrain components. Continued operation risks severe equipment damage and prolonged downtime.

Installation Tip

Ensure the bearing housing and shaft surfaces are thoroughly cleaned and free of any debris or burrs before installation. Use a proper press or induction heater to install the bearing, ensuring it seats evenly without cocking.

Service Note

Inspect the adjacent shaft, seals, and lubrication system for any signs of wear, leakage, or contamination.
