The SK350 top roller is a vital wear part in the undercarriage system of Komatsu SK350 series excavators (including SK350-8, SK350LC-8 models). It is mounted on the upper section of the track frame and works in conjunction with the track chain, idler wheels, and rollers to support the excavator’s weight and enable smooth track movement.
