BEARING - TAPER ROLLER (Komatsu KO3KA2111310)

A worn taper roller bearing can cause uneven rotation and premature failure in rotating assemblies. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3KA2111310. The bearing type uses conical rollers arranged between an inner and outer race to support combined radial and axial loads. A common failure consequence is increased friction leading to overheating and eventual seizure of the supported shaft. During operation, the tapered design allows the bearing to handle thrust loads in one direction while maintaining smooth rolling contact. The item ships at approximately 0.803 pounds. Verify the serial number or application, then call (562) 693-7748.
