The single row deep groove ball bearing is the most popular type of rolling bearing. Because the inner and outer raceway radii are only slightly larger than the ball diameter,

it has considerable axial load carrying capacity in either direction, as well as radial loading. It is suitable for high speeds and can be supplied with shields or seals - for example, suf?x ZZ is added for shielded type, and suf?x 2RS is added for sealed type.

The shielded types have a running clearance between the inner race and the metal shield; whereas, the sealed types (with seals made from synthetic rubber) make contact with the inner race. Both shielded and sealed bearings are supplied with the correct amount of lithium base grease, which has an operating temperature of -30 to +120°C

(-22°F to +248°F).

Cages are normally two pieced pressed steel. For higher speeds, machined brass cages and reinforced plastics are used. Plastic cages are limited on operating temperature to about 120°C (248°F) maximum.

Deep Groove Ball Bearing can also be supplied with snap ring and groove, which provide a simple and space-saving means of locating the bearing in the housing. Bearings with this feature have the suf?x NR added to the designation.
