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.
