摘要： A rolling, sliding part is made from a bearing steel, and the rolling, sliding surface thereof has a surface layer portion which is 56 to 64 in Rockwell C hardness, up to 12 vol. % in retained austenite content and 4 to 6 degrees in the X-ray half value width of martensite. Even if made from a common bearing steel, the rolling, sliding part is reduced in the likelihood of developing a WEA or like fatigue structure, consequently exhibiting a prolonged rolling, sliding life for use under severe conditions involving a high temperature, high speed, high load or high vibration.

摘要： A sealing device for a rolling bearing includes: a seal mounting groove formed to a shoulder of a raceway groove of a fixed ring; a circumferential step formed to a shoulder of the raceway groove of the rotational ring; and an annular resilient sealing member fit into the seal mounting groove, a sealing lip of the sealing member being brought into contact with a lateral surface of the circumferential step. The sealing member includes a fluoro resin and 10-60 parts by weight of a filler based on 100 parts by weight of the fluoro resin, and the filler includes a first filler having a Mohs hardness of 6 or more and 8 or less in amount of 25%-75% by weight or less of the filler, and a second filler having a Mohs hardness of less than 6 as the remaining portion.

摘要： A joint structure of an annular member and a shaft member softer than the former is produced by(a) providing a shaft member with an oil spreading over its circumference, the shaft member having a plurality of discrete grooves, on its circumference in an inclined angular configuration about the axis of the shaft member, and(b) press fitting the annular member to the bore of the annular member with an interference such that the inner periphery of the annular member bore meshingly expands into the grooves. Press fitting proceeds under resilient deformation of the inner periphery of the annular member in the boundary friction state. A continuous oil film remains on the mating surfaces while securing firm joint.
摘要翻译：通过（a）提供具有在其圆周上扩展的油的轴构件来制造环形构件和比前者更软的轴构件的接合结构，所述轴构件在其圆周上具有多个离散的凹槽，倾斜角关于轴构件的轴线的构造，以及（b）将环形构件压配合到环形构件的孔中，使得环形构件孔的内周面相互啮合地扩大到凹槽中。压边装置在边界摩擦状态下在环形构件的内周的弹性变形下进行。连续的油膜保留在配合表面上，同时固定牢固的接头。
