A method for manufacturing a component is provided. The method includes providing one or more notches on a surface of the component. Further, depositing a coating on the surface to provide a thickness of the coating on the surface, is performed. The method also includes removing, at least partially, the coating from the surface such that the thickness of the coating over the notches is different from the thickness of the coating on the surface adjacent to the notches.

A slide member having a slide surface (14) coated with a lacquer comprising a resin(16). The lacquer is in turn at least partly coated with a lipophilic composition coating (18). The lipophilic composition coating provides a slide layer (19) on the slide member with low friction.

A sealed thrust bearing includes an inner ring; an outer ring facing the inner ring in an axial direction; an elastic member that covers the inner ring so as to define: an inner elastic seal member that seals a space between an inner circumferential portion of the inner ring and an inner circumferential portion of the outer ring; and an outer elastic seal member that seals a space between an outer circumferential portion of the inner ring and an outer circumferential portion of the outer ring; and a lower member that is disposed below the outer ring for being assembled with the outer ring, and is provided with cation coating. The inner elastic seal member has a lip in pressure contact with an inner surface of one of a cylinder portion and a cylindrical portion of the lower member, and the outer elastic seal member has a lip in pressure contact with an upper surface of one of an annular ring portion and an annular portion of the lower member. The lip of the inner elastic seal member has an area including a portion in pressure contact with the lower member and is provided with an irregular portion having surface roughness (ten-point height of irregularities conforming to JIS B 0601-1994) from 20 mRz to 50 mRz.

A sliding member of the present embodiment includes: a lining layer including a Bi phase; and a coating layer containing Ni, the coating layer being provided on a surface of the lining layer, the coating layer partially forming an entrance portion that has entered the lining layer side at an interface with respect to the lining layer. At any observation region including the interface between the lining layer and the coating layer, a value R=S1/S2 of a ratio of a maximum area S1 of the Bi phase included in the lining layer to a maximum area S2 of the entrance portion that has entered the lining layer is 1.00?R?9.00.

A slide member having a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide member with low friction.

A large thrust ball bearing, retainer, and raceways, using a surface treatment such as hard anodize, lowers the friction and wear. The retainer, molded in synthetic resin with self-lubricated material reinforced with carbon fiber such as MoS.sub.2, and PTPE, eliminates the thermal viscosity. Multi-segment retainers, each with an inner race-guided configuration, an alternative ball pocket cross-section design with a slotted configuration, reduce the thermal effects, improve the producibility of the retainer, and reduce the manufacturing cost. The pocket design with an oval cross-section instead of a circular cross-section also reduces the localized thermal-induced effect which would otherwise result in a pinching condition between the ball and the retainer. The alternative slotted retainer pocket design increases the compliance between ball/pocket interfaces, which helps to reduce the dynamic effects. The ends of the retainer segments are designed to reduce the interactive transferring, circumferential force between two adjacent segments.

A plain bearing may comprise a bearing substrate, a bearing overlay, and an interlayer disposed between the bearing substrate and the bearing overlay. The interlayer may comprise hexagonal boron nitride.

A method of producing a bearing ring of a rolling element bearing. External surfaces of the bearing ring are provided with an electrically insulating coating. The method providing the steps of (i) providing a prefinished bearing ring made of bearing steel. The bearing ring has a hardened and machined raceway surface for accommodating at least one row of rolling elements; (ii) providing a first coating on all surfaces of the bearing ring; (iii) removing the first coating from the external surfaces of the bearing ring; and (iv) providing the electrically insulating coating on the external surfaces.

A slide member having a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide member with low friction.

A micro machine may be in or less than the micrometer domain. The micro machine may include a micro actuator and a micro shaft coupled to the micro actuator. The micro shaft is operable to be driven by the micro actuator. A tool is coupled to the micro shaft and is operable to perform work in response to at least motion of the micro shaft.
