    摘要: 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
