The Medium Series consists of single row radial Conrad-type bearings made with bores from 10 mm to 180 mm for light to moderate
radial loads, two-directional thrust loads, or a combination of both, where space is somewhat limited. This series is available
in open, shielded, or sealed types, as well as with snap rings.
