    摘要: A split cage includes a plurality of cage segments each having a pair of rim portions and a pair of cage bar portions, the cage bar portions and the rim portions defining a single pocket that accommodates a single tapered roller. Turning of each of the cage segments is guided by the tapered roller, the cage segments being arranged in a circular pattern along the circumferential direction of the split cage, in an annular space between inner and outer rings. Each cage segment has projections formed so as to project radially inward from the pocket, and formed at the rim portions. A projecting length of each projection is set to such a length that the projection is brought into contact with an outer peripheral side portion of the inner ring before the cage segment is detached from the tapered roller when the cage segment is displaced to the radially inside.

    摘要: A retainer to be installed in a linear motion guide unit is disclosed which composed of embracing parts to hold a roller on diametrically opposite sides thereof, and connecting flanges joining the embracing parts together with one another. The embracing parts to hold the roller between them are each made with a first lip raised above any one side thereof, and a second lip raised above another side thereof. The first and second lips raised in opposite direction are placed in an offset or staggered relation with one another in lengthwise direction of the embracing part or in axial direction of the roller so as to be tough to suffer any distortion and/or damage on molding operation. The retainer can sustain ample lubricant near the lips. The embracing parts come into rolling-contact with the rolling surface of the roller while the connecting flanges come into sliding contact with axially opposite ends of the roller.

    摘要: In a roller retainer assembly, a roller retainer 15 is thinned to retain individual one of plural rollers 7 circulating in a roller circulation path inclusive of linear and curved races and to hold opposite side surfaces of the roller 7 and front and rear surfaces thereof in the roller moving direction. A combination of linear and curve guide portions 16a and 16b different in inclination angle and a combination of linear and curve guide portion 17a and 17b different in inclination angle are formed respectively in opposite end surfaces of the roller retainer 15 in a retainer moving direction. In a linear race, the linear guide portions 16a and 17a come into contact with adjacent roller retainers 15 respectively. In a curved race, the curve guide portions 16b and 17b come into contact with adjacent roller retainers 15 respectively.

    摘要: A bearing has rolling elements separated by floating spacer elements. Some of the floating spacer elements provide solid lubricant for lubricating the bearing. Other floating spacer elements may be non-lubricating. The lubricant-providing elements are alternated with the non-lubricating elements to maintain the alignment and spacing of the rolling elements, thereby promoting proper operation of the bearings throughout the life of the lubricant.

    摘要: A rolling-element bearing cage or cage element includes at least one axial bridge region having first and second guide surfaces, the first guide surface and the second guide surface each have a recessed region axially between first and second non-recessed regions, at least one V-shaped receiving space in a radial outer surface of the rolling-element bearing cage or cage element configured to receive lubricant, and first and second fluid channels extending from the at least one receiving space to the recessed regions of the first and second guide surfaces. The fluid channels have rectangular cross sections, are about as wide as a width of the recessed regions, and are angled at an acute angle to a radial direction, and the receiving space is approximately as wide as the recessed regions.
