4V4445 Bearing — Cat 926 926a

This bearing is a vital component designed to support rotational movement and reduce friction within the power train or chassis systems of heavy equipment. Manufactured to meet rigorous quality standards, it offers enhanced longevity and reliability over a worn-out counterpart. Observable symptoms of failure include audible grinding noises, excessive heat generation, and a noticeable decrease in operational smoothness.

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 a failing bearing include intermittent whining or grinding sounds during operation, particularly under load. If ignored, the noise will become constant, accompanied by increased vibration and potential binding of the rotating component. Continued use risks severe damage to the shaft and housing, leading to unexpected equipment stoppage.

Installation Tip

Before installing, carefully inspect the bearing's raceways for any imperfections or signs of damage that may have occurred during shipping. Ensure the bearing is seated perfectly square in its bore to prevent binding and premature failure.

Service Note

Check the condition of the shaft or spindle that the bearing mounts onto, and clean the mounting bore thoroughly.
