This deep-groove ball bearing supports a rotating shaft within a housing, reducing friction between the stationary and rotating members. It carries radial loads and moderate axial loads in both directions. The 2RS suffix indicates the bearing is sealed on both sides with rubber contact seals, which retain grease and exclude contaminants such as dust and moisture. A worn or contaminated bearing produces a rough, grinding noise during rotation and may cause shaft misalignment or vibration in the driven assembly. The single-row raceway design is a standard metric size suited for general driveline and auxiliary shaft positions in the host machine. When replacing, press the bearing onto the shaft and into the housing bore using only the race faces to avoid brinelling the balls or damaging the seals.
