Double row deep groove ball bearings feature higher load ratings than single row bearings, but are very sensitive to misalignments. This series have the latest design (suffixed ‘B’) without filling slots.Fitted with polyamide cages (suffixed ‘TN’) as standard, pressed steel cages are also available. However, somedouble row deep groove "ball bearings" may have filling slots that limit the ability to support thrust loads.
 
Features :
1) Deep groove ball bearings mainly take radial load as well as take moderate axial load
2) With less coefficient of friction, high limiting speed, large size range and various structure
3) They are suitable of precision instruments, low noise motors, automobiles, motorcycles, and other common machinery
4) A widely used type of bearings in machinery industry

Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation. Consequently, they are available in many executions and sizes.

Deep groove ball bearing have various types in structure, beside open type bearings, shield or seals at both side can also be provided

Deep groove ball bearings are non-separable and require little attention or maintenance in service, capable of operating at high speeds and are widely used radial bearings. The inner and outer ring of single row deep groove ball bearings have a deep groove raceway, the bearings are mainly used to carry radial loads and a part of axial loads in two directions. This kind of bearing can carry much heavy axial loads after the increase of radial clearance, thus, it can take the place of high speed angular contact ball bearings.
