CATBearing & Bushing

9H9473 Race — Cat 561b 977D

This component serves as a hardened outer or inner ring for a bearing assembly, providing a precise raceway for rolling elements to travel within. Manufactured to meet OEM material and hardness standards, it ensures smooth and efficient rotation, unlike a worn race that may show pitting or spalling. Operators might experience increased vibration, noise, or binding in the affected component when this race begins to fail.

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 signs of a failing bearing race include a grinding noise that changes with speed or load, and increased vibration in the component. If ignored, the race will continue to degrade, leading to bearing failure, potential seizure of the component, and possible damage to surrounding parts. This could result in unexpected downtime and costly repairs.

Installation Tip

Ensure the mating surface in the housing or shaft is perfectly clean and free of any burrs or damage before attempting to press in the new race. Avoid cocking the race during installation, as this can lead to improper seating and premature failure.

Service Note

Always replace the bearing assembly (balls/rollers and cage) when replacing a bearing race.
