CATBearing & Bushing

6n2578 Bearing — Cat 120g 12g

This bearing is a critical component designed to reduce friction and support loads within rotating machinery. Manufactured to meet rigorous OEM standards, it offers superior load-bearing capacity and smoother operation compared to a worn bearing exhibiting roughness or excessive heat. Operators might observe increased noise levels, localized overheating, or binding 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 presents as an audible grinding or whining noise that changes with speed or load. This can escalate to noticeable heat generation around the component and increased resistance to rotation. If left unaddressed, the bearing can seize, potentially damaging the shaft and surrounding components.

Installation Tip

Ensure the bearing housing and shaft are meticulously clean before installation to prevent contamination. Never use excessive force or hammer the bearing into place, as this can damage the races and compromise its integrity.

Service Note

When replacing a bearing, it is advisable to inspect the shaft for wear, check seals for integrity, and ensure proper lubrication of the surrounding area.
