Claims

[Scope of utility model registration request]

(1) A cage 41 is arranged between the outer ring 31 and the inner ring 33, and the cage 41 has two annular parts 42 and 43 located apart in the axial direction and a plurality of annular parts 42 and 43 located apart in the circumferential direction. The two adjacent pillars 44 are integrally connected by a pillar 44.
In a roller bearing in which rollers 47 are arranged in pockets 45 surrounded by two annular portions 42 and 43, the retainer 41
is made of synthetic resin, and both axial ends 48 and 49 of the side surface of the column forming the pocket 45 are perpendicular to a plane 53 that includes the axis of the bearing and the axis of the roller. Contact portions 57 and 58 are provided on the inner side of the bearing and the outer side of the bearing from the plane 54 including the center, respectively, and contact portions 57 and 58 are in contact with the rolling surface 55 of the rollers during operation of the bearing, and the retainer 41 is adjacent to the outer circumferential surface of the column. The distance B between the outer circumferential surface of the column is shorter than the diameter of the opposing portion of the roller 47, and the distance C between the inner circumferential surface of the column and the inner circumferential surface of the adjacent column is the portion where the roller 47 is opposed. A roller bearing characterized in that each portion has a portion shorter than its diameter.

(2) Both ends 48, 49 in the axial direction of the side surface of the column and the annular portion 4
2.43. The roller bearing according to claim 1, which has a radial groove 65 at the boundary with 2.43.

(3) The roller bearing according to claim 1, wherein at least one of the outer circumferential surface 61 of the column and the inner circumferential surface 62 of the column has an axial groove 67.

(4) The roller bearing according to claim 1, wherein the roller bearing is a self-aligning roller bearing.

(5) The roller bearing according to claim 4, wherein the self-aligning roller bearing is a double-row self-aligning roller bearing.

(6) The clearance between the inner circumferential portion 75 and 47 of the annular portion on the side surface side of the bearing of the cage is the same as the gap between the outer circumferential portion 78 and 47 of the annular portion on the side surface side of the cage bearing. The roller bearing according to claim 5 of the utility model registration claim, which is larger than the gap between the roller bearings.
