Mancal de rolamento radial, em particular, mancal de rolamento inclinado de duas fileiras

A double-row angular contact bearing and which has outer and inner bearing rings with two rows of rolling elements disposed between the bearing rings that are held by two bearing cages interspaced at even distances. At least one row is configured as balls with parallel lateral faces that are symmetrically flattened. Both rows of rolling elements roll in adjacent races machined into the inner face of the outer ring and the outer face of the inner ring. The contact angle axes are pitched towards each other in an O-arrangement or X-arrangement and the races are axially delimited only on one side by shoulders. Additional clearance and supporting contours are formed at axial edge sections, opposite the shoulders, onto the races. The contours can be used to fit the balls into angular contact by axially inserting them into the clearance between the bearing rings and then tilting them into the races.
