Abstract: A vehicle wheel hub unit includes radially inner and outer rings made mutually rotatable by a plurality of rolling elements therebetween and an axially symmetric seal assembly. The seal assembly includes a shield mounted with an interference fit on the radially inner ring, and the shield has an annular flanged portion and a mounting portion integral with the annular flanged portion. The mounting portion is tubular and extends parallel to a bearing axis of rotation when mounted on the radially inner ring and makes a first circumferentially constant angle relative to a shield axis of rotation before being mounted on the radially inner ring, and the annular flanged portion is perpendicular to the bearing axis of rotation when mounted on the radially inner ring and makes a second circumferentially constant angle relative to the shield axis of rotation before being mounted on the radially inner ring.

Abstract: There is provided a grease composition for improving the chemical stability of the grease composition and increasing the fatigue life of a member in which the grease composition is used. The problems can be solved by a grease composition including a poly-α-olefin; a urea-based thickener; molybdenum dithiophosphate; and barium sulfonate, wherein a difference between an SP value of the urea-based thickener and an SP value of the poly-α-olefin is 3.5 or less.

Abstract: The invention relates to a rolling bearing with two bearing rings and rolling elements running between same, and a sensor for detecting movements and/or positions of the bearing rings relative to one another, wherein the sensor is fastened to one of the bearing rings and is directed towards a measurement surface on the other bearing ring, wherein said measurement surface comprises a contour projection projecting towards the sensor and/or a contour recess open towards the sensor in the form of a groove or blind hole, which projection or groove influences the measurement signal of the sensor and the movement of which relative to the sensor transverse to the main signal direction of the sensor modifies the measurement signal of the sensor.

Abstract: A support apparatus for a shaft system. The shaft system comprises a first shaft (1), a second shaft (2), and a bearing (3) arranged between the first shaft (1) and the second shaft (2); the first shaft (1) is sleeved at an outer peripheral side of the second shaft (2) and is able to rotate relative to the second shaft (2) by means of the bearing (3). The support apparatus is used for arranging at a first end in an axial direction of the shaft system, and the support apparatus comprises: shaft end support members (8, 15), at least a portion of the shaft end support members (8, 15) being rotatably supported in an axial direction at an outer side of a shaft end face of a first end of the second shaft (2); and connection assemblies (17, 14), where the connection assemblies (17, 14) in the axial direction of the shaft system are used for being connected between a first end of the first shaft (1) and the shaft end support members (8, 15). Further disclosed is a wind turbine. The present support apparatus may enable a bearing of a shaft system to essentially not bear a load or reduce an axial load borne, and the service life of the bearing is prolonged.

Abstract: A roller bearing includes inner and outer rings, and a plurality of rolling bodies configured to roll in two rows on corresponding raceways on the inner and outer rings. At least one of the inner ring and outer ring is split radially to form at least two ring portions. The raceway in an abutment region between the at least two ring portions has a ground recess locally deepening the raceway. Each ground recess on the outer ring has an arcuate course extending transversely to the abutment region, the greatest radial depth of the ground recess lies in the abutment region, and each ground recess extends in the circumferential direction of the raceway of the outer ring over a length which is at most the circumferential distance between the contact point of a first rolling body and the contact point of a second rolling body.

Abstract: An amount of decrease ΔC in an axial clearance of a hub unit bearing is found based on an amount of expansion ΔD of an inner ring of the hub unit bearing, which is the difference between the outer-diameter dimension D1 of the inner ring after the inner ring is externally fitted with a tubular fitting portion of a hub spindle of the hub unit bearing and after formation of a swaged portion of the hub spindle, the inner ring being held between the swaged portion and a stepped surface of the hub spindle, and an outer-diameter dimension D0 of the inner ring before the inner ring is externally fitted with the tubular fitting portion.
