CHAIN ROLLER (Komatsu KO34B-72-11150B)

KO34B-72-11150B: A worn chain roller can cause uneven chain travel and accelerated wear on surrounding components. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO34B-72-11150B. The chain roller is a cylindrical component that guides and supports the chain as it moves through its path. Its plain mechanical function is to reduce friction between the chain and the supporting structure. A common failure consequence is that a seized or worn roller can lead to chain misalignment and premature chain failure. Keeping the roller in sound condition helps maintain consistent chain tracking and load distribution. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 2.55 pounds.
