This cylindrical roller bearing supports radial loads within the transmission of the host tractor. It sits between the gear shaft and the housing, maintaining shaft alignment and reducing friction during power transfer. A worn bearing produces audible rumble and increased gear backlash, which can lead to accelerated wear on adjacent gear teeth. As an original component, it is manufactured to the same internal clearance and raceway geometry as the bearing it replaces, ensuring proper load distribution without requiring shimming or housing modification.
