摘要:
A needle roller bearing comprises an outer ring having a plurality of outer ring members split by split lines extending in an axial direction of the bearing, a plurality of needle rollers arranged on an orbit surface of said outer ring so that they can roll thereon, and a cage holding the needle rollers at intervals. The outer ring member has a projection serving as a positioning engaging part which engages with a housing for positioning, and an engaging click protruding from an axial end of the outer ring member inward along a diameter to prevent the cage from moving in an axial direction, in positions shifted from its circumferential center.

A needle roller bearing comprises an outer ring having a split part in a circumferential direction, a plurality of rollers which can roll along an inner diameter surface of the outer ring, and a cage holding the plurality of rollers. The outer ring has an engaging click protruding inward along a diameter at a width-direction end thereof to prevent the cage from moving in an axial direction.

A needle roller bearing (21) as a roller bearing comprises an outer ring (22) having a plurality of outer ring members (22a) and (22b) split by a split line extending in the axial direction of the bearing, and a plurality of needle rollers (23) arranged along the track surface of the outer ring (22). The outer ring member (22a) is in the form of a semicircular shape having a center angle of 180° and has an engagement click (22c) bent from one circumferential side end to the radial outer side. The two outer ring members (22a) and (22b) are connected in the circumferential direction to form the annular outer ring (22).

A needle roller bearing comprises an outer ring having a plurality of outer ring members split by a parting line extending in the axial direction of the bearing, and a plurality of needle rollers rotatably arranged on the raceway surface of the outer ring. Thus, a non-contact length “L” between the outer ring members and the needle roller at an abutment part of the adjacent outer ring members, and an effective length “w” of the needle roller has a relation such that L/w

摘要:
A positioning protrusion 14 is provided in a center of an outer diameter surface of a halved outer ring 11a in both circumferential and axial directions. The positioning protrusion 14 is configured to engage with a housing, which is placed on an outer diameter side of the halved outer ring, to position the halved outer ring 11a with respect to the housing. A protruding portion 17a and a recessed portion 17b are provided in each abutting portions 16a, 16b where a pair of the halved outer rings 11a abut on each other when fitted on a rotary shaft that is supported by a roller bearing. The protruding portion 17a and the recessed portion 17b are configured to mesh with each other to restrict axial movement of both halved outer rings 11a. The protruding portion 17a and the recessed portion 17b are point-symmetric with respect to a center 20 of the positioning protrusion 14.
