PURPOSE: To mount a rotary machine element directly and supporting it accurately with reduced parts and assembly man-hour by forming a mounting flange projected from the periphery of the outer ring in radial outward direction and integrally with the outer ring, and projecting both ends of an inner ring from both ends of the outer ring by more increasing the width of the inner ring than that of the outer ring.
CONSTITUTION: The width of an inner ring 2 is formed slightly larger than that of an outer ring 3, and both ends of the inner ring 2 are protruded from both ends of the outer ring 3. A mounting flange 5 is formed projectedly in radial outer direction and integrally with the outer ring 3 roughly at the center of the outer ring 3 in axial direction, and mounting holes 6 are machined at an appropriate space in circumferential direction of the flange. A cam laver 7 can be mounted directly to the mounting flange 5 formed projectedly on the periphery of the outer ring 3, and the cam lever 7 can be constructed of plate material, etc., at low cost. Also, the cam lever 7 can be supported on a shaft 15 through a unit bearing 1 and set at a fixed position in axial direction by contacting both ends of the inner ring 2 with supporting members 16a and 16b. Accordingly, the number of parts used and man-hour for assembly can be reduced and, therefore, cost can be reduced and accuracy in assembly can be increased since cumulative error will not be produced.
