CATBearing & Bushing

2K7979 Bearing — Cat 120g 120H

This bearing is engineered to provide smooth, low-friction rotational support for shafts and other moving components within the machine's various systems. It is built to withstand operational loads and maintain precise alignment, unlike a worn bearing that would develop excessive play and generate heat. Operators may observe increased noise, vibration, or a loss of smooth operation in the affected component 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

A failing bearing often first signals its distress with an audible change, such as a humming or grinding noise that intensifies with speed. If ignored, this can progress to noticeable vibration and increased heat in the component. Continued operation risks bearing seizure, which can cause significant damage to the shaft and surrounding components.

Installation Tip

Ensure the shaft and the housing are impeccably clean before fitting the bearing to prevent contamination. Always use a proper bearing installation tool or press to apply force evenly to the correct race, avoiding damage to the bearing elements.

Service Note

Check the shaft and housing for wear or damage when replacing this bearing.
