Ball bearing units consist of a precision wide inner ring bearing assembled into a housing made of cast iron or pressed steel. Units are pre-lubricated and are designed to slip fit on to the shaft. Locking method is either setscrew locking, eccentric self-locking or concentric. On cast iron and pressed steel units, the outside diameter of the bearing and the inside diameter of the housing are sphered, allowing the bearing to swivel within the housing to accommodate initial alignment.
