CATBearing & Bushing

2n2139 2N2138 — Cat 120g 120H

This is a CAT 2N2138 bearing, a crucial component for reducing friction and supporting rotational or linear movement within various machine systems. It is manufactured to precise tolerances to ensure smooth operation and longevity, unlike a worn bearing which would exhibit increased resistance and noise. Operators may notice increased vibration, grinding sounds, or premature wear on adjacent components when this bearing fails.

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

The initial symptom of a failing bearing is often an audible grinding or humming noise during operation. As the wear progresses, this noise will intensify, and increased vibration may be felt through the machine. If left unaddressed, the bearing can seize, potentially damaging the shaft or housing it is installed in.

Installation Tip

Ensure the bearing bore is perfectly clean and free of any burrs or contaminants before attempting installation. Press the bearing in squarely to avoid damaging the races.

Service Note

Inspect the shaft or housing for any signs of scoring or wear that may have been caused by the failing bearing.
