Single-row groove ball bearings are
the most common type of rolling bearings. Their use is very widespread.
The raceway grooves on both the inner and outer rings have circular
arcs of slightly lager radius than that of the balls. In addition to
radial loads, axial loads can be imposed in either direction. Because of
their low torque, they are highly suitable for applications where high
speeds and low power loss are required.
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.
