This deep-groove ball bearing supports a rotating shaft in the threshing drive or water pump assembly. It carries radial and moderate axial loads while maintaining shaft alignment within the housing. The rubber seal on both sides retains grease and excludes contaminants. A bearing that develops play or roughness will cause shaft misalignment, leading to premature wear of the driven component and increased vibration. As an original-manufacturer component, the seal profile matches the housing bore geometry, which prevents ingress during washdown. When replacing, ensure the new bearing is pressed squarely onto the shaft and into the housing bore without cocking.
