CATBearing & Bushing

5J1446 Bearing — Cat 245 245b

This is a heavy-duty bearing designed to withstand extreme loads and reduce friction in large-scale equipment. Manufactured to meet rigorous OEM standards, it ensures reliable rotation and extended component life, unlike a worn bearing which can cause increased resistance and noise. Operators may observe unusual noises from the drive axle or articulation points, excessive heat, or a noticeable decrease in steering or power transfer 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

Early indications of a failing bearing include a noticeable grinding or rumbling sound, particularly when turning or under load. If left unaddressed, this can lead to increased friction, heat buildup, and potential seizure of the connected component. Continued operation risks severe damage to the shaft and housing, leading to significant repair costs and operational downtime.

Installation Tip

Ensure the bearing seat and shaft are perfectly clean and free of any debris before installation. Avoid using excessive force or improper tools, which can damage the bearing races or cage.

Service Note

Inspect the surrounding seals and the shaft or bore for any signs of wear or damage during the bearing replacement process.
