  • Patent number: 8506166
    Abstract: Lubrication for rolling elements are made in a turnaround passage in an end cap to ensure proper and steady lubrication by the lubrication system simple in construction, with accompanying sustainable maintenance-free condition for lubrication. The end cap has an inward end surface facing directly towards the end surface of the carriage of the slider and having a concavity which sinks below the inward end surface and has openings communicating with the turnaround passages. A porous compact impregnated with lubricant is fitted into the concavity in a fashion exposed in part to the turnaround passage through the openings so that the rolling elements rolling through the turnaround passages, as coming into rolling-contact with the parts of the porous compact exposed out of the openings, are applied with the lubricant.

  • Patent number: 8408803
    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.
