摘要： A high speed anti-friction bearing includes an internal impeller mechanism to provide improved high speed lubrication for the anti-friction elements (15). At high bearing speeds the impeller mechanism (33) scoops liquid lubricant from a liquid annulus centrifugally generated on the outer wall (11) of the bearing. The scooped liquid is hurled inwardly onto the anti-friction elements (15) as a fine mist. The bearing lubrication process is achieved with minimum heat generation and minimum energy loss insofar as the anti-friction elements do not plow through large masses of lubricant.

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： [Problem] There is provided a wheel rolling bearing unit capable of preventing grease leak even if the interference of the sealing member for sealing the clearance between the inner and outer rings is made small. [Means for Resolution] The wheel rolling bearing unit 10 according to the present invention is equipped with an inner shaft 12; an outer ring 11 disposed concentrically on the outer peripheral side of the inner shaft 12; a plurality of balls 13 disposed between these; and a pair of cages 20 for retaining the balls 13 in the circumferential direction. On the inner peripheral surface of each of the pair of cages 20, a concave section 25 being dented to the outside in the radial direction to hold grease is formed in the range from the axial outside end section 22c to the inside end section.
