    摘要： An angular contact ball bearing includes: an inner ring including a shoulder portion-side end surface; an outer ring which includes a counterbore-side smaller-diameter portion and a counterbore-side end surface disposed axially inwardly of the shoulder portion-side end surface of the inner ring; a plurality of balls arranged in a circular row between the outer ring and inner rings; a cage for holding the balls; and a cylindrical guide portion which is provided at and communicates with the counterbore-side smaller-diameter portion and guides a ball-cage assembly in which the balls and the cage are assembled together when the ball-cage assembly is inserted into the outer ring. When the ball-cage assembly is inserted into the outer ring disposed horizontally, the ball-cage assembly is supported by the counterbore-side smaller-diameter portion and is prevented from being inclined by the guide portion.

    摘要： A rolling bearing apparatus includes inner and outer rings in which a preload applying unit applies a preload to the outer ring. If a fluid pressure in a fluid supply passage is higher than a first set pressure, then fluid is supplied to a pressure chamber via a check valve, and if a pressure becomes lower than the first set pressure, then fluid is supplied from a hydraulic pump to the pressure chamber via the check valve. If the pressure becomes higher than a second set pressure, then the fluid is discharged from the pressure chamber via a relief valve, and if the pressure within the pressure chamber becomes higher than a third set pressure, which is higher than the first set pressure but is lower than the second set pressure, then the supply of fluid is stopped. Thus, the pressure within the pressure chamber is maintained between the first and second set pressures.

    摘要： A tapered roller bearing for a pinion shaft according to the invention includes an inner ring that has an outer circumferential surface on which an inner ring raceway surface is formed and that is integrally fixed to a one-end-side of the pinion shaft, an outer ring that has an inner circumferential surface on which an outer ring raceway surface is formed and that is fixed to a housing, and a plurality of tapered rollers rollably interposed between both of the raceway surfaces. An annular oil reservoir groove for storing lubricating oil is formed in a distal end portion at the one-end-side in an axial direction of the inner circumferential surface by being recessed thereinto adjacent to the outer ring raceway surface.

    摘要： When a fluid pressure in a fluid supply passage is higher than a first set pressure, a fluid in the fluid supply passage is supplied to a pressure chamber via a check valve, and when the pressure becomes lower than the first set pressure, the fluid is supplied from a hydraulic pump to the pressure chamber via the check valve. When the pressure becomes higher than a second set pressure, the fluid is discharged from the pressure chamber via a relief valve, and also when the pressure within the pressure chamber becomes higher than a third set pressure which is higher than the first set pressure but is lower than the second set pressure, the supply of the fluid is stopped. With this system, the pressure within the pressure chamber is maintained at a level between the first and second set pressures.
