The insert bearing is actually a variant of the deep groove ball bearing. Its characteristic is that its outer ring outer diameter surface is a spherical surface, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering.

DHK insert bearings usually have a widened inner ring, which is fixed to the shaft by an eccentric locking ring ((GRAE...NPPB RAE...NPPB RALE...NPPB GE...KRPB3 GE...KRRB E...KRRB GE...KLLHB series) or fixed to the shaft by two screws (GAY...NPPB, GLE...KRRB GYE...KKRB series).

In addition, there are 2...NPPB series with the same dimensional data as 62 series bearings, but the outer diameter is spherical. How to use an adapter sleeve to fix the GSH...RRB series on the shaft.

Insert bearings are preferentially suitable for occasions that require simple equipment and parts, such as agricultural machinery, transportation systems or construction machinery.
