SEAL - DUST (Komatsu KO175-63-75190)

A damaged dust seal can allow contaminants into the protected area, leading to accelerated wear of adjacent components. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO175-63-75190. The seal functions as a barrier to exclude dirt, debris, and moisture from a rotating or sliding shaft interface. Its plain mechanical role is to maintain a close fit around the moving member while preventing external particles from entering. When the seal fails, the resulting contamination often causes premature failure of bearings or bushings. Keeping a dust seal in sound condition helps preserve the service life of the surrounding assembly. Verify the serial number or application, then call (562) 693-7748.
