摘要： A tandem angular ball bearing is provide that prevent damage from occurring to the rolling surfaces of the balls during assembly and transport to an extent that would cause an excessive decrease in life of the balls, and that can maintain excelled durability without the occurrence of excessive vibration and noise during operation. In order to accomplish this, the entire portion of the inner peripheral surface of an outer ring (5b) from a small-diameter side outer ring raceway (11) to the continuous section (25a) that is continuous with the end surface (23) on the large inner diameter side of the outer ring (5b), and the entire portion of the outer peripheral surface of an inner ring (6b) from a large-diameter side inner ring raceway (12) to the continuous section (25g) that is continuous with the end surface (14) on the small outer-diameter side of the inner ring (6b) are polished smooth surfaces having no indifferentiable corner sections in the cross-section shape. Moreover, the outer ring (5c) comprises groove shoulder sections (16a, 16b, 17a, 17b) in at least one of the portion on one side in the axial direction of the large-diameter side outer ring raceway (10), and the portion on the one side in the axial direction of the small-diameter side outer ring raceway (11), and in the portion on the other side in the axial direction of the large-diameter side outer ring raceway (10) and in the portion on the other end in the axial direction of the small-diameter side outer ring raceway (11).

摘要： An encoder 12 a characteristic of which is changed alternately at an equal interval in a circumferential direction is supported/fixed onto a hub 4 concentrically with the hub4. A sensing portion of a sensor 13 supported on the outer ring 3 is positioned in close vicinity to a sensed surface of the encoder 12 to face thereto. Width dimensions of first and second sensed portions provided onto the sensed surface are changed continuously in a direction along which a to-be-sensed load is applied. Since a pattern according to which an output signal of the sensor 13 is changed is changed pursuant to a change of the load, the load is derived by observing this pattern. The output signal is also utilized to sense a rotation speed of the hub 4 in ABS or TCS control.

摘要： A tapered roller bearing having construction that improves durability during a state of insufficient lubrication by sufficiently lengthening the time until rotation becomes impossible due to seizure. Oil retaining concave sections 19 that are recessed outward in the radial direction are formed in portions on the inner circumferential surface of the large-diameter rim section 12 e of the retainer 5e whose phase in the circumferential direction coincides with the pockets 15e. The portion of the bottom surface of each of the oil retaining concave sections 19 that is open to the inside surface of the pocket 15e face concave section 20 that is formed in the end surface 10 on the large-diameter side of tapered roller 4a that is held inside the pocket 15e. When lubrication becomes insufficient, lubrication oil that remains in the oil retaining concave sections 19 is effectively used for lubricating areas of sliding contact between the end surfaces 10 on the large-diameter side and the inside surface in the axial direction of a large-diameter side flange section 8.

摘要： A telescopic shaft for steering of a vehicle is assembled in a steering shaft and includes a male shaft and a female shaft that are so fitted as not to be rotatable but to be slidable. Rolling members are fitted through an elastic body for pre-load between at least a pair of axially-extending grooves formed in an outer peripheral surface of the male shaft and in an inner peripheral surface of the female shaft. A slide member is fitted in between at least another pair of axially-extending grooves formed in the outer peripheral surface of the male shaft and in the inner peripheral surface of the female shaft. When a steering toque is equal to or smaller than a predetermined level, the elastic body for the pre-load exhibits a low rigidity characteristic as the elastic body performs pre-load action. When the steering torque is equal to or larger than the predetermined level, the slide member exhibits a high rigidity characteristic as the slide member engages with the pair of axially extending grooves.
