NADELLAGER MIT GETEILTEM NADELKAEFIG

A needle roller bearing of a type empolying a generally cylindrical needle roller retainer of two-piece construction for supporting a plurality of needle rollers. The roller retainer is comprised of retainer segments each having opposite side edges. The retainer segments are connected together by means of at least one bond deposit filling up a gap between one of the opposite side edges of one of the retainer segments and a mating one of the opposite side edges of the other of the retainer segments, respectively. As a bonding material forming the bond deposit, a viscous material containing, as a principal component, vinyl acetate resin, or a hot-melt bonding material, both exhibiting a bondability lowering a high temperature, may be employed. When the needle roller bearing is in use, the bond deposit detaches from the gap or melt to separate the retainer segments from each other, allowing the separated retainer segments to function individually to minimize a fretting phenomenon.
