Also a method of forming a rolling-element bearing cage or rolling-element bearing cage segment from aluminum alloy AA6082 and/or AA 7020.

A transfer system for transporting objects is disclosed. It includes a guide rail, which has a light-metal main body and at least one guide element, which is connected to the light-metal main body and has a guide surface. A slide for accommodating at least one object and a bearing, which interacts with the guide element and supports the slide on the guide rail in such a way that the slide can move linearly is also included. The guide rail has at least one magnetic fastening means, which makes it possible to temporarily fasten the guide rail by magnetic clamping, in particular in order to process the guide surface.

An oil-retaining sintered bearing in which friction coefficient can be reduced and a sliding property as a bearing can be improved by supplying a sufficient amount of oil to a sliding surface and preventing the supplied oil from moving to an interior from the sliding surface; a sliding surface 3 supporting an outer peripheral surface of a shaft and a helical oiling surface 4 around a shaft axis of a bearing hole are adjacently formed on an inner peripheral surface of the bearing hole into which the shaft is inserted; a surface open rate at the sliding surface 3 is not larger than 10%; and a surface open rate at the oiling surface exceeds 10%.

A wheel bearing apparatus for rotatably supporting a wheel includes an inner member having two rows of raceway grooves on its outer circumference, an outer member having two rows of raceway grooves on its inner circumference, and rolling elements interposed between the raceway grooves of the inner and outer members. The raceway grooves of the inner and outer members are formed by hardened steel cutting. In relation to at least the raceway groove on the outboard side out of the raceway grooves of the inner member, h/d exceeds 0.50 where h is the depth of the groove and d is the diameter of the rolling elements. This provides a wheel bearing apparatus being compact and capable of withstanding a high applied load without inviting an increase in the size of the bearing.

This slewing bearing includes: an inner ring having an inner-ring-side rolling-element rolling surface on an outer peripheral surface; an outer ring having an ring-side rolling-element rolling surface on an inner peripheral surface, and being arranged outside the inner ring such that the outer-ring-side rolling-element rolling surface faces the inner-ring-side rolling-element rolling surface; and a plurality of rolling elements rollably disposed on a rolling-element rolling passage formed by the inner-ring-side rolling-element rolling surface and the outer-ring-side rolling-element rolling surface. The inner ring or the outer ring is configured to have combination of a press-worked part having a contour shape formed by pressing work, and a removal-processed part including at least the inner-ring-side rolling-element rolling surface or the outer-ring-side rolling-element rolling surface formed by removal processing. Such a configuration makes it possible to provide a slewing bearing having a structure that can be manufactured at low cost while maintaining a certain performance.

A manufacturing method for a sliding bearing including half members, obtained by splitting a cylinder in half in a direction parallel with an axial direction, arranged in an upper and lower direction, may include a first step including forming a narrow groove extending in the circumference direction on an axial direction end of one of the half members on a lower side, on a downstream side in a rotation direction, a second step including performing shot blasting on a surface of the narrow groove; and a third step including forming coating layers on a surface of the half member. The coating layers may be formed only on an upstream-side end and a downstream-side end as parts of the narrow groove.
