    摘要: In a conductive rolling bearing comprising an inner ring (11), an outer ring (12), a plurality of rolling elements (13) mounted between the inner ring and the outer ring, and seal members for sealing the space between the inner ring and the outer ring, the seal members have one end thereof secured to one of the inner ring and the outer ring and the other end thereof in an elastic, sliding contact with a seal wall surface (18) formed on the other. The free end (19) of the seal member (15) is bent outwardly of the bearing and the seal member (15) is in a sliding contact with the seal wall surface (18) on its bent portion (20). This arrangement gives the effects of providing a low, stable torque for the bearing and of improving the seal performance of the bearing. This conductive rolling bearing is used in a steering assembly of an automobile and bearing assemblies having a bearing near electrical devices.

    摘要: An annular oil filter for covering an open end of a rolling bearing has its outer edge held between two annular retainer plates, the outer edges of which are held by a rubber mold to unite them into one body. The rubber mold is resiliently received in an annular groove formed in the inner wall of an outer ring at its end. The oil filter has its inner edge in contact with a shoulder formed on the outer wall of an inner ring.

    摘要: A relief groove (23) is provided at a corner in which a track surface (21) and a flange surface (24) cross, in an inner ring (20) of a cylindrical roller bearing. A chamfer (42) is provided at a corner part in which a rolling surface (41) and an end surface (43) cross, in a cylindrical roller (40). When it is assumed that the height of the chamfer (42) from the rolling surface (41) is “h” and the curvature radius of the chamfer is “R”, the relation such that 1.0≦R/h≦1.5 is satisfied.

    摘要: A strength of a machined cage for a cylindrical roller bearing is increased without reducing a bearing life. An integral machined cage for a cylindrical roller bearing includes: a pair of side plates (42, 44); a plurality of columns (46), which are arranged in a circumferential direction, for connecting the pair of side plates (42, 44); pockets (48) formed between the adjacent columns (46); and relief portions (50) provided at four corners of each of the pockets (48), in which as viewed from a section perpendicular to an axis of the cage, the columns (46) have side surfaces each constituting a circular arc shape, and the relief portions (50) are in parallel to the side surfaces of the columns (46).

    摘要: It is desired to form a flange and roller guide surfaces on each retainer of a self-aligning roller bearing easily and with high precision. Each punched retainer include a large-diameter annular portion (1), a small-diameter annular portion (2), a plurality of bridges (3) extending between the annular portions (1) and (2) and defining a plurality of circumferentially separated pockets (4) therebetween, roller guide surfaces (1a) that can be brought into sliding contact with end surfaces of respective convex rollers (5), which revolve around the axis of the bearing, and a flange (6) formed by radially bending the large-diameter annular portion (1). The roller guide surfaces (1a) comprise punched sections formed on the portions of the inner peripheries of the pockets (4) located at the large-diameter annular portion (1), and the flange (6) has a Bent Portion® that extends the entire circumference of the large-diameter annular portion (1). With this arrangement, the roller guide surfaces (1a) can be formed by punching only, which is a essential step. This makes it possible to make uniform the flatness of the back and front surfaces of the flange and its bent angle over the entire circumference thereof.
