Transmission bearings which are often referred to as insert bearings or wide inner ring, 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.
Transmission 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 but normally do not enable axial displacement of the shaft. Transmission bearing units offer a simple, cost-effective solution that can provide a number of benefits. Available in both steel and stainless steel.
