摘要： A strength of a machined cage for a cylindrical roller bearing is increased without reducing a bearing life. An integral machined cage for a cylindrical roller bearing includes: a pair of side plates (42, 44); a plurality of columns (46), which are arranged in a circumferential direction, for connecting the pair of side plates (42, 44); pockets (48) formed between the adjacent columns (46); and relief portions (50) provided at four corners of each of the pockets (48), in which as viewed from a section perpendicular to an axis of the cage, the columns (46) have side surfaces each constituting a circular arc shape, and the relief portions (50) are in parallel to the side surfaces of the columns (46).

摘要： A roller bearing has spacers interposed between its rollers. The roller bearing also has a high permissible rotational speed which is achieved by allowing a lubricant to flow smoothly around rolling surfaces so that the stirring resistance of the lubricant due to the spacers is reduced. The roller bearing includes a plurality of rotatable rollers interposed between an inner ring raceway surface and an outer ring raceway surface and spacers provided between adjacent rollers. Each of the spacers includes extended portions facing roller end faces of the rollers at both axial ends thereof.

摘要： A method for assembling a roller bearing having rollers and spacers interposed between the adjacent rollers includes alternately disposing, along the inner circumference of an outer ring, the rollers and the spacers. Two spacers are then placed along inner portions of rolling contact surfaces of the rollers having been disposed. The last roller is then inserted toward the outer ring so that the spacers placed on both sides are allowed to slide, whereby the last roller is mounted on the inner circumference of the outer ring.

摘要： A roller bearing having spacers interposed between rollers is provided. During operation of the bearing, the spacers are prevented from being pressed by adjacent rollers against an inner ring or inner ring, so that heat generation and wear of the spacers at a guiding surface are reduced. The roller bearing includes an outer ring, an inner ring, a plurality of rollers, and a plurality of spacers interposed between adjacent rollers. Surfaces of each spacer that face respective rolling contact surfaces of the rollers each have a concave shape that extends across a pitch circle of the rollers, and the spacers are guided by one of the outer and inner rings. When each of the spacers is held between the adjacent rollers, a clearance is formed between the one of the outer and inner rings and the spacer.

摘要： [PROBLEMS] A roller bearing is provided which has spacers interposed between rollers. During operation of the bearing, the spacer is prevented from being pressed by adjacent rollers against an inner ring or inner ring, so that heat generation and wear of the spacers at a guiding surface are reduced.[MEANS FOR SOLVING THE PROBLEMS] The roller bearing includes an outer ring (12), an inner ring (14), a plurality of rollers (16), and a plurality of spacers (18) interposed between adjacent rollers (16). Surfaces (18b) of each spacer (18) that face respective rolling contact surfaces (16a) of the rollers each have a concave shape that extends across a pitch circle of the rollers (16), and the spacers (18) are guided by one of the outer and inner rings (12, 14). When each of the spacers (18) is held between the adjacent rollers (16), a clearance Sr is formed between the one of the outer and inner rings (12, 14) and the spacer (18).
