Deep groove ball bearings

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 bearing 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. 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 bearing is consist of inner ring outer cage and balls, has three type according its sealing, first open type without sealing, meatal seal double sides we call ZZ, ruble shield double sides we call it 2rs. deep groove ball bearings mainly take radial load as well as moderate axial load. When they just take radial load, the contact angle is zero. When with a big radial clearance, the deep groove ball bearing could take large axial load, with a property of angular contact ball bearing. Deep groove ball bearing has a high limiting speed, with less coefficient of friction.
