Claims

[Scope of utility model registration request]

In a pivot type angular contact ball bearing consisting of an outer ring, a plurality of balls arranged so as to be able to roll inside the outer ring, and a cage for the balls, the cage is arranged between an upper edge of an inner circumferential surface and a lower edge of an outer circumferential surface. It consists of a cylindrical ring with an obliquely chamfered edge, and has a pair of groove-shaped cuts opening in opposite directions on both end surfaces of the ring, respectively, on the inner and outer circumferential surfaces of the cylindrical ring. The groove-shaped cuts are formed so as to be in contact with each other on the virtual cylindrical surface approximately in the middle between the inner circumferential surface and the outer circumferential surface, and a plurality of these pairs of groove-shaped cuts are arranged in the circumferential direction. Alternately opposing bottom portions of the groove-shaped cuts are formed on a ball support surface having a center centered in the axial direction of the intermediate cylindrical surface, and straight portions of the adjacent inner and outer groove-shaped cuts are formed on a ball support surface centered at the axial center of the intermediate cylindrical surface, and straight portions of the adjacent inner and outer groove-shaped cuts are formed on a ball support surface centered at the axial center of the intermediate cylindrical surface. By forming the surfaces alternately connected in the axial direction through a common surface near the center of the direction, and forming at least the bottom part of the inner groove-shaped cut and the inner edge of the straight part to be smaller than the diameter of the ball. A pivot type angular contact ball bearing characterized by having a ball pocket and having the entire cage molded from an elastomer material.
