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.
