This deep-groove ball bearing supports a rotating shaft within the header or forage harvester drive system. It carries radial and moderate axial loads from the belt or chain drive that powers the gathering and feeding components. The 2RS designation indicates two integral rubber seals that retain grease and exclude dust and moisture, which is critical in the high-debris environment of a harvesting header. A worn bearing produces rumble or shaft wobble, leading to belt misalignment and reduced drive efficiency. The manufacturer machines the races and balls to the same tolerance class as the original assembly, so the bearing seats in the housing without shimming.
