CATBearing & Bushing

4587940 Bearing — Cat 120M 120M 2

This is a precision-engineered bearing designed to support rotating shafts and reduce friction in the drive train or other heavy-duty mechanical systems of CAT equipment. Manufactured to meet stringent OEM quality standards, it offers exceptional durability and smooth operation, unlike a worn bearing that can cause resistance and noise. Operators may observe increased vibration, heat generation, or a whining sound emanating from the affected area 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 increase in operating temperature and audible noise, such as humming or grinding. If ignored, the bearing can seize, leading to significant damage to the shaft and surrounding components, potentially causing a loss of drive or operational function. Continued use risks severe mechanical damage and costly repairs.

Installation Tip

Always ensure the bearing housing and shaft surfaces are perfectly clean and free from any debris or old lubricant residue. Never use a hammer to drive the bearing into its seat; use a proper press or installation tool.

Service Note

Inspect the shaft and housing for any signs of scoring, wear, or contamination that may have contributed to the bearing's premature failure.
