ER22-KFF - ER-K - MB ER Adapter Series Centrik-Lok Ball Bearing Insert

ER type bearing inserts are commonly used in mounted bearing assemblies. The bearings have basic standard metric ball bearing dimensions with the exception of widths and the inch size bore of the inner ring. Because of the metric ball bearing basis of design and sizing, the ball complement (the number and size) for a given size bearing is comparable with other manufacturers. The ER type insert is designed for set screw locking to the shaft, with the bearing mounted in the customers housing. It incorporates standard seals and comes with a outside diameter mounted snap ring for axial location, eliminating housing counterboring. ER series bearings are intended for rigid mounting, as the bearings have a cylindrical outside diameter and not the spherical outside diameter of standard insert bearings.
