In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common. For big deep groove ball bearings, machined brass cages are used. Machined cages are also used for high speed applications.
