BEARING - MAST ROLLER (Komatsu KO34B-72-53430)

KO34B-72-53430: A worn mast roller bearing can cause rough mast movement and uneven load handling. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO34B-72-53430. The bearing type supports the roller that guides the mast assembly during vertical travel. 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 jerky mast operation. The item ships at approximately 4.31 pounds. Verify the serial number or application, then call (562) 693-7748.
