CATBearing & Bushing

2291009 Bearing — Cat 320C 320D

This is a critical component within the undercarriage or swing system, designed to reduce friction and support heavy loads during operation. It is manufactured to meet stringent CAT material and dimensional standards, ensuring superior durability compared to a worn bearing that exhibits scoring or excessive play. Operators may notice increased noise, vibration, or reduced maneuverability when this bearing 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

Initial signs of failure may include a grinding noise during operation or increased heat generation around the bearing housing. If ignored, the bearing can seize, leading to restricted movement and potential damage to adjacent components. Unaddressed failure can result in significant downtime and costly repairs to the drive or swing system.

Installation Tip

Ensure the bearing housing is thoroughly cleaned and free of any old lubricant or debris before installing the new bearing. Avoid using excessive force or hammering on the bearing during installation, as this can damage the raceways.

Service Note

Inspect the seals and surrounding components for wear or damage when replacing this bearing.
