This single flange bottom track roller (also called a lower roller or track support roller) is a direct aftermarket replacement for the Fits John Deere (Fits JD) 450 and 550 series undercarriage systems. Bottom rollers support the weight of the machine on the track chain, and replacement is essential when rollers develop leaks, flat spots, or excessive wear. Note: This is NOT a Maximum-Life style roller and does not fit Maximum-Life undercarriage configurations.
