    Abstract: A feed screw including a screw shaft (1), a nut (2) meshed with the screw shaft (1), and a plurality of rolling members (3) inserted between the screw shaft (1) and the nut (2), wherein a solid film (5) of a fluorine-containing polyurethane polymer is formed on any portions in rolling/sliding contact. The molecules of this solid film (5) have urethane bonds, and form a three-dimensional reticular structure. Therefore, the film is unlikely to separate, peel off or wear. Accordingly, the feed screw produces less dust, improves lubricating property and thus elongates its life.

    Abstract: A rolling sliding part is in relative rolling contact or sliding contact with a companion member, and is formed on a contact surface thereof with a lubricating film (5) composed of a polymer which contains fluorine with a functional group and in which particles (6) of polytetrafluoroethylene resin are dispersed and mixed. The lubricating film (5) exhibits a favorable lubricating property and generates little dust, and the particles (6) mixed in the film provide a favorable cushioning action under loading. As the lubricating film (5) itself and the particles (6) are fluorine based, they provide for a good compatibility therebetween.

    Abstract: 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

    Abstract translation: 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。

    Abstract: A linear motion ball bearing (A) comprises a rail (1), a moving body (2) slidably fitted to the rail and a plurality of rolling bodies (4) disposed between the rail (1) and the moving body, and rolled and circulated with their relative sliding movement, wherein a solid film (16) of a fluorine-containing polyurethane polymer compound is formed at least at the rolling/sliding portions of the constituent elements. The molecules of this solid film (16) have a urethane bond and a three-dimensional net-like structure. Therefore, wear besides separation and peel-off is limited. In consequence, the suppression of dusting and the lubricity are improved, and a long life is achieved.

    Abstract: 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.
