摘要： A solid film (5) of a fluorine-containing polyurethane polymer is formed on at least one of the constituent elements (inner and outer races (1 and 2), rolling member (3) and retainer (4)) of a rolling-contact bearing (A). The molecules of the solid film (5) of the fluorine-containing polyurethane polymer have urethane bonds, and form a three-dimensional reticular structure. Therefore, the film is unlikely to separate, peel off or wear, the occurrence of the dust can be restricted, and lubrication property can be improved.

摘要： This invention relates to grease for roller bearings which contains poly- alpha -olefin synthetic oil or diphenylether synthetic oil, urea thickening agent, and organic antimony compound or organic molybdenum compound; and a roller bearing in which this grease is sealed. The organic antimony compound or organic molybdenum compound reacts with the rolling surfaces of the inner and outer races and the surfaces of rolling elements in the bearing to form compound films which contribute to the reduction of the tangential force, and to prevent the generation of an excessively large tangential force during the high-speed rotation of a rotary part. This enables the lifetime of a roller bearing, which is used, especially, under severe conditions, to be prolonged.
摘要翻译：本发明涉及含有聚-α-烯烃合成油或二苯醚合成油，脲增稠剂和有机锑化合物或有机钼化合物的滚子轴承用润滑脂。和一个这种润滑脂被密封的滚子轴承。有机锑化合物或有机钼化合物与内圈和外圈的滚动表面以及轴承中的滚动元件的表面反应形成有助于减小切向力的复合膜，并且防止过度的产生在旋转部件的高速旋转期间的大的切向力。这使得特别是在恶劣条件下使用的滚子轴承的使用寿命得以延长。

摘要： A mechanical part having a rolling contact surface (11a) with many isolated minute recesses. A maximum height Ry of a roughness curve R obtained by cutting this contact surface (11a) with a plane perpendicular thereto is 1-3 mu m. An attenuation peak height RPK obtained on the basis of a load curve M obtained from the roughness curve R has relation of RPK/Ry
摘要翻译：一种具有滚动接触表面（11a）的机械部件，具有许多隔离的微小凹部。通过用与其垂直的平面切割该接触表面（11a）而获得的粗糙度曲线R的最大高度Ry为1-3μm。基于从粗糙度曲线R获得的负载曲线M获得的衰减峰值高度RPK相对于最大峰值高度Ry具有RPK / Ry <0.1的关系。这表示接触表面具有低分布和大深度的微小凹陷，接触表面层靠近其上表面的部分相对平滑。靠近上表面的平滑部分能够确保足够宽的接触表面积，并且由于分布不均匀和深度较大的微小凹陷而能够形成足够大容量的储油器。

摘要： Formed in a spindle (2) is a cooling processing liquid passage (19) extending axially. Fixedly provided on a rear end of a housing (1) is a cylindrical cooling processing liquid supplying member (29) adapted to be inserted into the passage (19) with a gap therebetween. A radial spacing between an outer peripheral surface of the supplying member (29) and an inner peripheral surface of the passage (19) is made larger than a radial spacing between touchdown bearings (9) and the spindle (2) when the spindle (2) is supported in non-contact condition. Formed on the inner peripheral surface of the passage (19) is a spiral groove (21) to feed a cooling processing liquid forward over a distance from a rear end of the passage (19) which is longer than a distance, by which the supplying member (29) is inserted from the rear end of the passage (19) during rotation of the spindle (2). Formed in a rear end of the housing (1) is a processing liquid reservoir (32) communicating with a gap between the spindle (2) and the supplying member (29). Formed in the housing (1) is a drainage hole (33) communicating with the reservoir (32). Provided between the housing (1) and the spindle (2) is a labyrinth seal (28) for providing sealing between an area of the reservoir (32) in the housing (1) and an area forwardly thereof. Accordingly, it is possible to prevent failure of the entire magnetic bearing spindle apparatus.

摘要： A roller bearing consisting of races (1, 2) consisting of a metal or ceramic material, rolling elements (3) provided rollably inside the races (1, 2) and consisting of a metal or ceramic material, and a lubricating film (5) provided so as to cover the rolling portions of the races (1, 2) and/or rolling elements (3) and obtained by disperse-mixing a synthetic fluoro-resin in a resin binder having imide bond or amide-imide bond, and removing hydrocarbon gas from the resultant mixture. Since a temperature for firing this lubricating film (5) is set to such a level that permits a hydrocarbon gas to be discharged completely from the lubricating film (5) during a firing treatment for the lubricating film (5), the discharge of a hydrocarbon gas from the lubricating film (5) in a high-temperature environment is prevented.
