Bearings • Ball Bearings
Ball bearing is a rolling element bearing with balls that separate the moving elements. They are used to reduce rotational friction while holding up radial and axial loads. Two races, one fixed, hold the balls and transmit loads through the balls. The rolling balls produce a low coefficient of friction. Ball bearings typically have a low load capacity but allow for misalignment of the inner and outer races. They can be made of various materials, including stainless steel and plastic. They have several common designs such as angular contact, axial, thrust, sealed, flanged, self aligning and deep groove. Various sizes and configurations are available; large, miniature, inch, metric, double and single row.

The SKF ball bearing line-up includes deep groove, angular contact, angular contact thrust, self aligning and thrust types. Other offerings include cylindrical, tapered, needle and spherical roller designs. SKF has a standard line of deep groove ball bearings that feature single row or double row configurations, come in stainless steel or hybrid designs, and can handle high temperatures.
American deep groove and angular contact ball bearings are made from AISI steel. ABEC Class 1/ ISO Class Normal.
Scheerer is a manufacturer of ball thrust, roller thrust, radial ball and radial roller bearings. The majority of their products are made from SAE 52100 alloy steel. The retainers are made from precision machined centrifugally cast bronze or phenolic. Scheerer ball thrust bearings are self aligning and single or double acting. Their roller thrust designs come in plain type, self aligning, single or double acting. Scheerer radial ball bearings come in either single row or double row deep groove and are self aligning. Their radial roller designs include cylindrical, single row or multi-row.
