Deep groove ball bearings Non-separable, for operations at high speeds, of simple design and little maintenance, RKB deep groove ball bearings are the most versatile and popular bearings in rolling applications. The internal designs are the Conrad assembly (the majority of the production) and the filling slot assembly (for special applications with cage or with full ball complement). The single row deep groove ball bearings can take radial and double direction axial loads. They have limited abilities to compensate for errors of misalignment. Because of the values, in order to avoid inadmissible high additional loads and noise increase as a result of complex relationships among several influencing factors, the permissible misalignments are considered those between 2 to 10 minutes of arc depending on the bearing series. The basic design of RKB deep groove ball bearings is open type either with boundary metric dimensions in accordance with ISO 15:1988 or with inch dimensions as per American AFBMA specifications. The version with a snap ring groove on the outer ring (suffix N) for the easy axial location in the housing is in accordance with ISO 464. When required by the application, these ball bearings are also produced in the sealed and shielded versions that have the seal recesses in the outer rings (suffix 2RS and ZZ). In case of bearings with shields, there is a small interstice between the shield and the rib of the inner ring; in case of bearings with seals, the oil resistant elastic rubber lip runs on the groove on the side of the inner ring or directly on the outside surface of the inner ring. Bearings sealed and shielded on both sides manufactured in series are delivered filled with normal lithium base grease of consistency NLGI 2 or with special grease suitable for specific applications. Bearings with shields have been designed first of all for those cases where the inner ring rotates. RKB single row deep groove ball bearings are produced as standard to normal tolerances P0. Higher precision bearings in accordance with ISO 492:2002 can be considered. The radial clearance, according to ISO 5753, can be normal or in different classes as per international specifications. 6
