Mounted Bearings | Bearing Servi
The bearing may also have a cylindrical OD with a slip-fit in the mounting to allow axial freedom. Mounted bearing units are also available with cylindrical, spherical and roller bearings. Mounted roller bearings are often used for heavier-duty applications than ball bearings, and therefore may require more rigid locking to the shaft.
