摘要： A retainer made of a synthetic resin for use in a deep groove ball bearing is proposed of which the lubricity has been improved. The retainer includes a cylindrical first split retainer member (41) having a first axial side, and a cylindrical second split retainer member (42) having a second axial side coupled to the first axial side of the first split retainer member (41). Circumferentially spaced apart first and second cutouts (45 and 50) are formed in the first axial side of the first split retainer member (41) and the second axial side of the second split retainer member (42), respectively, which define respective pockets for receiving balls with the split retainers (41 and 42) coupled together. A coupling arrangement (X) is provided between the first and second split retainer members (41 and 42) which is adapted to engage the split retainer members (41 and 42) when the split retainer members (41 and 42) are coupled together, thereby keeping the split retainer members (41 and 42) axially inseparable from each other. With the retainer mounted in a deep groove ball bearing, when the outer race (11) and the inner race (21) rotate relative to each other, since the first and second split retainer members (41 and 42) rotate at different peripheral speeds due to a difference in diameter therebetween, pumping action is produced in the bearing, which causes a forced flow of lubricating oil in the bearing.

摘要： A bearing ring for a roller bearing includes a raceway for at least one roller that includes an at least partially spherically formed roller end surface having a first curvature. A flange for transferring axial forces extends from an end of the raceway and has a flange surface that faces towards the roller end surface. A spherical flange surface section having a second curvature is defined on the flange surface. The first curvature differs from the second curvature such that a first gap (d1) exists between the spherically formed roller end surface and the spherical flange surface section. The flange surface also includes an opening flange surface section having a third curvature, which is less than the second curvature, such that a second gap (d2) exists between the roller end side and the opening flange surface section. The second gap is larger than the first gap.

摘要： A buried plug has interference which is made to exert a load or stress less in a widthwise direction of the guide rail than in a lengthwise direction of the guide rail, thereby protect raceways on the guide rail against any deformation such as bulge. The buried plug has a mating zone to press fit into a counterbore of a bolt hole and a leading zone to guide the mating zone into the counterbore. Let assuming a definition that a direction perpendicular to a lengthwise direction of the guide rail is referred to a direction opposed to the raceway surface or the widthwise direction of the guide rail, the interference exerting a force on the counterbore in the widthwise direction is determined less than the interference exerting the force on the counterbore in the lengthwise direction of the guide rail.

摘要： Construction of a thrust roller bearing with races is achieved in which a function of preventing a cage 3, first thrust race 4a and second thrust race 5a from separating from each other can be maintained, the amount of eccentricity that is allowed between a pair of members that rotate relative to each other can be increased, and the amount of lubricant that can flow inside the bearing can be increased. The outer diameter of the outer-diameter side flange 8a that is formed around the outer circumferential edge section of the first thrust race 4a is 60 mm to 120 mm, the inner diameter of the inner-diameter side flange 11a that is formed around the inner-circumferential edge section of the inner-diameter side flange 5a is 40 mm to 80 mm, and the internal gap is 1 mm to 2 mm. Therefore, outer-diameter side locking sections 9a are intermittently formed in the circumferential direction on the tip-end edge of the outer-diameter side flange 8a.

摘要： In a copper-based sliding material in which a Cu alloy layer contains 5% to 30% by mass of Bi, and the balance consisting of Cu and an unavoidable impurity, Bi is dispersed as particles of a Bi phase in the Cu alloy layer, and the mass ratio of the particles having a particle size of 2 to 50 μm and a circularity of 0.1 to 0.7 is 30% or more in the entire Bi phase in the Cu alloy layer, so that the particles of the Bi phase are uniformly dispersed in the Cu alloy layer. Therefore, the particles of the Bi phase in the Cu alloy layer are sequentially exposed to a sliding surface as wear of the sliding material progresses while excessive flow-out of molten Bi is prevented, so that improved seizure resistance is achieved.
