摘要： The surface roughness of the rolling surface 2 of the roller 1 along both the axial and circumferential direction is 0.06 .mu.m RA or less, while the surface roughness of the opposing inner ring raceway 4 is 0.08 to 0.15 .mu.m Ra along the axial direction, and 0.04 or less along the circumferential direction, whereby the heat generated by the roller bearing is kept to a minimum, and the danger of burning of the roller bearing is reduced.

摘要： The rolling/sliding outer ring of the cam follower apparatus is made to withstand peeling very well, even in severe lubrication conditions, by forming a surface layer in the depth 0 to 50 .mu.m from the outer peripheral surface of the outer ring, such that the maximum residual compressive stress in this surface layer is between 50 and 110 kgf/mm.sup.2, the hardness of this surface layer is between Hv 830 and Hv 960, and the amount of residual austenite in the surface layer is at least 7 volume %, and formed with continuous minute irregularities on the surface with convexities of the irregularities having an equivalent roundness diameter up to 15 .mu.m for the case that the concavities of the irregularities are assumed to occupy 80% of the total surface area, while the inner peripheral surface of the outer ring is superfinished.

摘要： A magnet is embedded in an outer rotational shaft provided in a bearing hole of a case, and an outer magnetic circuit and an inner magnetic circuit are formed on the outer peripheral surface and inner peripheral surface of the outer rotational shaft, respectively. In a magnetic fluid seal device, magnetic fluid is filled in minute gaps coming in contact with the outer peripheral surface and inner peripheral surface of the outer rotational shaft, and the two rotational shafts can be strongly sealed by the magnetic circuits formed by a magnet. As a result, the rotational shafts can be rotated while supported in a non-contact style. In addition, the dimension can be reduced, and the number of parts can be reduced.

摘要： An outer shell member is fixed to the lower end of a rotational shaft so as to wrap around a unit main body from the lower side thereof to the outer periphery thereof. The gap between the rotational shaft and the unit main body is magnetically sealed by a ferrofluid seal portion. A bearing portion is provided at the lower end portion of the unit main body between the unit main body and the outer shell member. Purge gas is supplied to the gap between the rotational shaft and the unit main body at a position nearer to the reaction container than the ferrofluid seal portion and in the neighborhood of the ferrofluid seal portion.

摘要： A magnetic fluid sealing device basically includes a housing; a rotating shaft rotatably supported in said housing by bearings; and a magnet and magnetic pole pieces, which are arranged in such a manner as to encircle said rotating shaft with micro gaps put therebetween. A magnetic field formed by magnet forms magnetic fluid films in the micro gaps to thereby magnetically seal high pressure/vacuum regions positioned at both ends of the rotating shaft. The sealing device is characterized in that the housing, and a mounting cap for fixing the magnetic fluid sealing portion and the bearings at specific positions in the housing are made of a magnetic material, and the materials of the housing and bearing and the dimension of the mounting cap are changed, to thereby reduce a leaked magnetic flux.
