DOUBLE ROW ANGULAR BALL BEARINGS

PROBLEM TO BE SOLVED: To materialize considerable simplification of assembly by improving a double row angular ball bearings in which an outer ring 1 and an inner ring 2 are provide, a plurality of balls 3.1, 4.1 guided in the retainers 3.2, 4.2 respectively are supported on a plurality of shoulders 1.1, 1.2, 2.1, 2.2 of the bearing rings, and the diameters of ball travel tracks of respective retainers are different individually. SOLUTION: Both retainers are formed as a plastic made retainer with a window provided with a pocket for accommodating balls 3.1, 4.1. Either of the retainers is equipped on an end of the axial inside with a plurality of interval holding members 3.5, 4.5 and a plurality of retaining projections 3.4, 4.4 having equal mutual intervals in the peripheral direction. These retaining projections 3.4, 4.4 are engaged with the grooves 2.3, 1.3 included in the inner ring or the outer ring. The interval holding members of one retainer is made to prevent the other retainer from moving in the axial direction. COPYRIGHT: (C)2004,JPO
