    摘要： A needle roller bearing is directed to avoid a possibility that an inner peripheral surface of a bore in a housing may be ground or scraped by an edge defining a peripheral lip region of an opening in an outer race when a needle roller bearing is to be press-fitted into the bore in the housing and also to eliminate the need to adjust the position of a roller retainer while increasing a physical strength of the roller retainer. For this purpose, the outer race is formed with a first opening having a pair of axially spaced tabs bent so as to incline radially inwardly of the outer race from the remaining portion of the outer race. The roller retainer is in the form of a tubular member having a circumferentially continuous wall formed with a second opening at a location aligned with the first opening in the outer race. The roller retainer has a substantially intermediate portion protruding radially outwardly so as to have an outer diameter greater than that of any one of the opposite ends of the roller retainer.

    摘要： 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.

    摘要： A rolling member which has improved strength and permits stable formation of oil films between its rolling surface and its mating surface and which shows a long life even under unfavorable lubricating conditions. The surface of the rolling member is subjected to heat treatment while nitriding. The rolling member is then treated to form minute recesses in its surface so that such surface has a surface roughness parameter RMS of not less than 0.10 .mu.m and a negative SK value. Thus, the surface strength of the rolling element increases and the oil film forming rate improves. The surface of the rolling member is less likely to suffer peeling damage and wear. Its life is prolonged.

    摘要： It is aimed to prolong the life of a rocker arm in which rollers are housed in a full type form between a ring and a pin from a viewpoint completely different from the idea of improving the material. It is proposed to suitably control the relation between clearances in circumferential and radial directions for the rollers housed in a roller housing space formed between the outer peripheral surface of the pin and the inner peripheral surface of the ring.

    摘要： A shell type needle roller bearing for a universal joint is provided which can eliminate radial gaps. A plurality of needle rollers are mounted in an outer ring which has a cylindrical portion adapted to be fitted in a bearing ring formed in a bifurcated piece of a yoke and having a bottom at one end. The cylindrical portion is formed by three arcuate wall portions having equal circumferential lengths to each other. When a trunnion of a universal joint is inserted into the shell type needle roller bearing, the arcuate wall portions are resiliently deformed radially outwardly through the needle rollers, so that the needle rollers are pressed against the outer circumferential surface of the trunnion by the recovering resilience. This prevents formation of radial gaps.
