CATBearing & Bushing

6K8074 7L3283 — Cat 518 920

This is a high-quality replacement bearing, crucial for reducing friction and supporting loads in rotating assemblies. It is manufactured to meet rigorous OEM standards, ensuring smoother operation and longer life than a worn bearing with flattened raceways or damaged rollers. Operators may experience increased vibration, noise, or a noticeable decrease in equipment performance 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 symptoms of a failing bearing include a faint grinding noise or slight increase in operational vibration. If left unaddressed, the noise will become louder, and vibration will intensify, potentially leading to seizure of the rotating component. This can result in significant downtime and damage to adjacent parts.

Installation Tip

Ensure the bearing seat in the housing and the shaft are perfectly clean and free from burrs before attempting installation. Avoid using excessive force or hammering, which can damage the bearing's internal components.

Service Note

Inspect the shaft and housing for any signs of wear or damage, and check the lubrication system supplying the bearing.
