BEARING - BALL DOUBLE SEAL (Komatsu KO452299017)

A worn bearing can cause shaft misalignment and premature component failure. The Komatsu catalog reference KO452299017 identifies this aftermarket replacement part as a ball bearing with double seals. Its plain mechanical function is to support rotating shafts while reducing friction between moving surfaces. A concrete generic failure consequence is that seal degradation allows contamination ingress, leading to noisy operation and eventual seizure. Keeping a bearing in sound condition helps maintain consistent rotational accuracy under load. This item ships at approximately 0.278 pounds. Verify the serial number or application, then call (562) 693-7748.
