摘要： A retainer for a needle roller bearing which can prevent a film of lubricating oil from being broken due to its needle roller retaining claws and thus prevent peeling of the needle rollers. Outer-diameter claws and inner-diameter claws are provided on roller guiding surfaces on both sides of each crossbar portion of the retainer to retain the needle rollers in pockets defined between the adjacent crossbars. In the case of an outer-diameter guide type retainer, the outer-diameter claws are provided at a stepped portion formed on the outer-diameter surface of each crossbar. In the case of an inner-diameter guide type retainer, the inner-diameter claws are provided at a stepped portion formed on the inner-diameter surface of each crossbar.

摘要： A roller with cage assembly 11 comprises a plurality of crowned rollers 12 each including a column part 12a having a constant diameter and inclined parts 12b connected to both sides of the column part 12a and inclined to reduce the diameter gradually, and a cage 13 having a pair of ring parts 14 and 15, a plurality of pillar parts 16 connecting the pair of ring parts to each other, pockets 17 formed between the adjacent pillar parts 16 to house the rollers 12, and guiding surfaces 16d having a predetermined width in a radial direction on wall surfaces of the pillar parts 16 opposed to the column part 12a. Thus, when it is assumed that a length from an end face 12c of the roller 12 to the boundary part between the column part 12a and the inclined part 12b is Dp, and an axial shortest distance from the wall surface of the pocket 17 opposed to the end face 12c of the roller 12 to the guiding surface 16d is A, the relation between them satisfies that Dp

摘要： A retained roller assembly, capable of facilitating the lubricating functionality, includes a cylindrical roller retainer having a plurality of pockets defined therein and arranged in a circumferential direction thereof, rollers accommodated within those pockets, respectively, and a roller retaining projection formed in opening edges of side faces, opposite to each other in the circumferential direction and situated on an inner diametric side and an outer diametric side, respectively. A roller guide face for guiding the corresponding roller is provided at an axial position on the side faces of each of the pockets that are different from the associated roller retaining projection. An annular recessed portion is provided in axially opposed ends of an inner diametric surface of the retainer so as to deploy over the entire periphery of the retainer.

摘要： A retainer-equipped roller includes a retainer (12) having a pair of ring parts (14) separated in an axis O direction and column parts (15) arranged circumferentially at regular intervals so as to form pockets (22) and connect the pair of ring parts (14), and a plurality of rollers (11) arranged in the pockets. The roller (11) has a chamfered part (13) provided between a roller end face and a roller rolling surface (11t). The column part (15) is positioned on a radial outer side of a pitch circle PCD of the roller (11), and a distance between the circumferentially adjacent column parts (15 and 15) is smaller than a diameter of the roller (11). The pair of ring parts (14) has a pair of projection members (16) projecting such that their tip ends are opposed so as to come close to each other, in circumferentially the same position as the column part (15), and in a position on a radially inner side of the pitch circle PCD of the roller (11). The tip ends of the pair of projection members (16) abut on the chamfered parts (13) provided at both ends of the roller (11) and hold the roller between the pair of ring parts (14).
