Y-bearings, which are usually referred to as insert bearings, are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a certain locking device enabling quick and easy mounting onto the shaft.
Y-bearings are available singly or as units. Y-bearing units consist of a housing, bearing and seal that is pre-assembled and greased at the factory. These ready-to-mount units can accommodate moderate initial misalignment (Demo) but normally do not enable axial displacement of the shaft.
