Single row angular contact ball bearings: can only bear axial load in one direction. Such bearings in bearing pure radial load, because the rolling body load line of action and radial load line of action is not in the same radial plane, resulting in internal axial force, so must be installed in pairs to use.
Single row deep groove ball bearing: in addition to bear radial load, but also can bear two directions of axial load. Friction torque is small, most suitable for high speed rotation, low noise, low vibration applications, in addition to open, there are steel plate dust cover bearings, plus rubber seal bearings, or in the outer ring with the outer diameter of the stop ring bearings.
SKF single row deep groove ball bearing basic design has open type and sealed type. For manufacturing reasons, and sealed bearings or dust bearings of the same size open type bearings, the outer ring may also have a seal groove. Bearings with dust caps or seals on both sides are maintenance-free products with lifetime lubrication. These bearings can not be cleaned, and the temperature should not exceed 80 degrees Celsius.
Single row thrust ball bearing is a kind of separated bearing, shaft ring “seat ring can be separated from the cage “steel ball assembly. Shaft ring is with the shaft of the collar, seat ring is with the bearing seat hole collar, and shaft clearance between.
