摘要： The integrated unit (10) comprises an encoder (20) of plastoferrite supported by an annular rigid insert (30). A rubber body (40) is vulcanized or overmoulded on the support (30) and holds the encoder (20) stably in an annular seat (31-33) of the support (30). The rubber body (40) forms one or more static (41) and/or dynamic (42, 44) sealing lips.

摘要： An object is to provide a rolling bearing device 11 which allows checking if its oil supply unit 13 is functioning properly, under an assembled state without any need for disassembly or communication lines extended to the outside. The device is provided as a combination of a rolling bearing 11 and an oil supply unit 13 which includes at least: a lubrication oil tank 46, a pump 45 which sucks lubrication oil from the lubrication oil tank 46 and discharges the lubrication oil from a discharge port; a driving section 44 which drives the pump 45; and a generator section 41 which supplies the driving section 44 with electric energy. The oil supply unit 13 is attached to a fixed-ring-side member 12b of the rolling bearing 11 or a spacer 16 adjacent to the rolling bearing. The oil supply unit 23 further includes, within itself, a communication unit 49 which transmits operation information of the oil supply unit 23 to an outside.

摘要： A rolling element bearing includes an inner race (2) and an outer race (1) and at least one row of rolling elements (3) located between these races, and a pair of sealing rings (5) mounted on either side of the rolling elements, whereby each ring (5) is attached at one of its circumferential edges to the race (1) located opposite it, while the other circumferential edge is located at a distance from the other race (2) so that an annular gap (9) exists between this edge and this race. The aforementioned other circumferential edge of the sealing ring, which is located at a distance from the race (2) located opposite it, is formed by the part (7) of the ring (5) - adjacent to this edge - which is bent inward over an angle of about 90°, whereby the end (8) of this part (7) is bent inward again, at an angle of about 90°.

摘要： One object of the present invention is to provide a wheel bearing apparatus which can reduce the frictional torque of the sealing lips and thus reduce the rotational torque of the sealing apparatus with selecting best characteristics and combinations of both the bearing grease and the sealing grease which can prevent mixture of them by suppressing their flowability. According to the present invention there is provided a wheel bearing apparatus for a vehicle comprising an outer member; an inner member including a hub wheel and at least one inner ring; double row rolling elements freely rollably contained between the inner raceway surfaces of the inner member and the outer raceway surfaces of the outer member; and seals mounted within annular openings formed between the outer member and the inner member characterized in that at least one seal of the seals comprises a core metal press-formed of steel sheet including a cylindrical fitting portion adapted to be press-fitted into the inner circumference of the end of the outer member via a predetermined interference and a radial portion extending radially inward from the end of the fitting portion, and further comprises a sealing member of synthetic rubber formed with a plurality of sealing lips and integrally adhered to the fitting portion of the core metal by vulcanizing adhesion; that bearing grease is contained within the bearing in a sealed manner and sealing grease is applied to the sliding portions of the sealing lips; that both the bearing grease and the sealing grease use same thickener and the worked penetration of 350 or less; and that the kinematic viscosity of base oil of the sealing grease at 40°C is set to 70% or less of that of the bearing grease at 40°C.
