SEAL - DUST (Komatsu KO4347251)

A damaged dust seal can allow contaminants to enter a shaft housing, accelerating wear on internal components. The Komatsu catalog reference for this aftermarket replacement part is KO4347251. This seal type functions as a barrier that excludes dirt and debris from rotating or sliding shafts. A common failure consequence is premature bearing or bushing degradation due to abrasive particle ingress. In applications where shafts cycle frequently, a compromised dust seal often leads to increased friction and eventual scoring of the shaft surface. This item ships at approximately 0.03 pounds. Verify the serial number or application, then call (562) 693-7748.
