BEARING - MAST ROLLER (CAT CT2I3550)

CT2I3550: A worn mast roller bearing can cause rough carriage movement and accelerated track wear. This aftermarket replacement part references the CAT catalog and carries the cross-reference number CT2I3550. The bearing type supports the mast roller assembly, enabling smooth vertical travel of the carriage. A plain mechanical function of this bearing is to reduce friction between the roller and its mounting surface. A concrete generic failure consequence is that a seized bearing can lead to roller flat-spotting and eventual jamming of the mast assembly. Verify the serial number or application, then call (562) 693-7748.
