4n3982 Bearing Set (2Pcs/Set) — Cat 950

This is a set of two high-quality bearings designed to reduce friction and wear between moving components in heavy machinery. Manufactured to meet stringent OEM standards, these bearings ensure smooth operation and longevity, unlike worn parts that exhibit increased play and surface damage. Operators may notice increased noise, reduced performance, or overheating of the affected component when these bearings begin 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 bearing failure include unusual noises like grinding or knocking, and a noticeable increase in operating temperature. If ignored, the wear will accelerate, leading to reduced component efficiency and potential seizure. Continued operation risks severe damage to adjacent components and extended downtime.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installation to prevent contamination. Avoid using excessive force or improper tools when pressing the bearings into place, as this can cause damage.

Service Note

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