    Abstract: A self-aligning roller bearing includes an outer ring, an inner ring, spherical rollers, a cage having a plurality of pockets that contain the spherical rollers, and a guide ring. Each spherical roller may be rotated on an imaginary line passing through a contact point at which the spherical roller contacts an outer raceway surface and a contact point at which the spherical roller contacts an inner raceway surface. Each pocket has a clearance between the pocket and a corresponding spherical roller, and the size of the pocket is set so that the rotation of the corresponding spherical roller is limited. The guide ring has such a side-surface shape that a small clearance is ensured between the spherical roller and the guide ring even when the spherical roller is rotated, in the pocket, on the imaginary line by a maximum amount at which the rotation of the spherical roller is limited.

    Abstract: A separator 8 including a solid lubricant is disposed between adjacent rolling elements 7. Relative movement of the adjacent rolling elements 7 and the separator 8 in a direction of separating apart in a circumferential direction is restricted by restricting members 10, and the restricting members 10 are disposed at plural locations in the circumferential direction. A minute gap α is provided between the adjacent restricting members 10, to allow relative movement therebetween. This can provide a solid-lubrication rolling bearing capable of stably preventing rotational locking and unintended disassembling of the bearing for a long period.

    Abstract: A rolling bearing which is capable of preventing the rolling elements from dropping out from between the inner and the outer rings even when the separators have been worn to an advanced stage. A rolling bearing includes: a plurality of rolling elements arranged between an inner and an outer rings; and a plurality of prismatic separators disposed in a circumferential direction between the rolling elements. The separator includes integrally therewith a metal band on at least one of its outer surfaces including those which face the inner or the outer ring, or at least one of its axial side surfaces, excluding however, surfaces which face the circumferential direction and make contact with the rolling elements. The metal band has a narrower width than a width of the separator in the circumferential direction, and prevents wear of the separator from advancing beyond a certain extent.

    Abstract: An ultrathin cross-roller bearing composed of outer and inner rings, more than one roller rolling through between the outer and inner rings, and a separator interposed between any two adjoining rollers. With the ultrathin cross-roller bearing constructed as stated earlier, the separator lying between the adjoining rollers is in the form of right cylinder better for keeping constantly the roller in proper posture, getting the bearing itself downsized and lightweight as small as possible, and further making sure of positive lubrication. The outer and inner rings are each made into one-piece construction. The inner ring has an inside diameter in a range of from 20 mm to 50 mm. The roller used in the ultrathin cross-roller bearing has a diameter of 2 mm to render a transverse section given by a product of a radial height and a bearing width in transverse section small or ultrathin in thickness.

    Abstract: A ball screw unit has a plurality of partition-rooms each of them accommodating a spacer ball interposed between two load carrying balls. The partition room is formed into two oblique frustum shaped recesses each of them extends a flared mouth tilted downwards to the longitudinal axis of the ball screw unit. The partition room is made of elastic polymer material to facilitate pushing the spacer ball into an oblate ellipsoidal hole opened on the partition room, and the hole is also communicated with the two recesses. With this structure, the spacer balls can be held stably in the partition rooms without the fear of escaping or occurrence of disorganized ball squeezing during operation of the ball screw unit. Besides, the dimension of spacer ball may be made as small as possible so as to increase the number of load carrying balls thereby resulting in improvement of load carrying capability of the structure.

    Abstract translation: 滚珠丝杠单元具有多个分隔室，每个分隔室容纳夹在两个承载球之间的间隔球。 分隔室形成为两个倾斜的截头圆锥形凹部，每个凹槽都延伸出向下倾斜到滚珠丝杠单元的纵向轴线的喇叭口。 分隔室由弹性聚合物材料制成，以便于将间隔球推入分隔室开口的扁圆形椭圆形孔中，并且孔也与两个凹槽连通。 通过这种结构，间隔球可以稳定地保持在分隔室中，而不用担心在滚珠丝杠单元的操作期间逃逸或发生无组织的滚珠挤压。 此外，间隔球的尺寸可以尽可能小，从而增加承载球的数量，从而提高结构的承载能力。

    Abstract: A spacer structure for cross rollers comprises a frame and four protruding wings, the protruding wings are arranged in pairs on opposing sides of the frame and outwardly extend therefrom. The two inactive end surfaces of the roller are confined between the paired protruding wings of the spacer. The slenderness ratio of the roller is designed to be 0.7-0.98 for facilitating installation of the roller between the paired protruding wings of the spacer, and such arrangement can effectively reduce the contact area between the spacer and the roller. The paired opposite protruding wings can provide a stable positioning effect to the end surfaces of the roller.

    Abstract: A hollow ball structure, for use in a ball bearing application, having two half shells constructed of powdered material made porous to absorb a lubricant therewithin to be automatically exuded onto the surface of the bearing and bearing races, and thereby provide a self-lubrication feature to the structure. The powdered ball bearing may be utilized in a bearing assembly in alternate relation with both solid and other types of hollow ball structures to thereby provide both strength, flexibility and lubrication.
