CATBearing & Bushing

6H3566 6I8860 — Cat 120 120b

This component serves as a critical bearing, facilitating smooth rotational movement within the machinery's drive train or undercarriage system. Manufactured to precise tolerances, it offers superior wear resistance and load-bearing capacity compared to a worn or damaged bearing. Operators might observe increased noise, vibration, or a noticeable decrease in operational efficiency 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

Early indications of bearing failure include a subtle grinding noise during operation or increased vibration. If ignored, the noise and vibration will intensify, potentially leading to binding or seizure of the rotating component. Continued operation with a failing bearing risks severe damage to the shaft, housing, and surrounding drivetrain components.

Installation Tip

Ensure the bearing bore and shaft are meticulously clean before installation to prevent premature wear. Avoid using excessive force or hammering on the bearing during installation, as this can damage the races and compromise its integrity.

Service Note

Inspect the shaft and housing for any signs of wear or damage when replacing this bearing.
