7224 A5 High Precision Bearing Size 120x215x40 mm Angular Contact Ball Bearing

1.·It can bear radial and axial combined load or pure axial at the same time;

·Small running resistance and high limit seed; · High rotation accuracy; ·Low noise and vibration; ·Single row angular contact ball bearings can only bear one direction of axial force, usually used in pairs to balance the axial force.

3.Ruben Bearing Features :

The raceways of both the inner and outer rings of this bearing type are made with a set contact angle. These bearings are non-separable. Since the balls are inserted utilizing counter-bore construction, a larger number of balls can be installed than in the case of Deep-groove ball bearings. Standard cage materials may be pressed steel, high-strength brass, or synthetic resin. Cage material is dependent on the bearing series and or service condition. Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction. This bearing type is generally used in pairs to handle the induced load resulting from the internal axial force generated by the applied radial load. When mounting two single bearings in adjacent positions, NACHI provides these combination parts (pairs) with preadjusted clearance. Paired combination bearings are matched sets. Combination or paired bearings can be arranged BACK-TO-BACK (DB), FACE-TOFACE (DF), or in TANDEM (DT). DB or DF sets can sustain bidirectional axial loads
