Product Overview
The top roller supports the upper track run, helping keep the chain aligned between the front idler and drive sprocket. A seized or worn carrier roller can increase track drag and uneven wear.
RD411-22900 is widely cataloged as a Kubota top-roller reference for several 4- to 6-ton excavator families. Serial and undercarriage revisions should still be checked.
