( 30… 2RS Series & ZZ Series, 38… 2RS & ZZ Series Double Row Contact Ball Bearings
Double row angular contact ball bearings can absorb comparatively large radial load, axial load and moment load. Compared to single row angular contact ball bearings they have higher rigidity which can bear upsetting moment so that they are especially adequate for situations which need high rigidity. The gradient between inner ring and outer ring is limited and the inclination angle is dependent on the inner gap, size, inner design, the force and moment on bearing. But the maximum permissible inclination should ensure that the additional stress is not too strong. Double row angular contact ball bearings use nylon cage and brass cage generally. When mounting we should take notice that if one side of the bearing has filling slot, we should let the side which has no filling slot absorb the main load.
