The invention relates to a bearing cover (3) for a split bearing arrangement (1), which in addition to the bearing cover (3) comprises a bearing block (2), wherein the bearing cover (3) comprises clamping surfaces (7), which in the assembled state of the bearing arrangement (1) bear on counter clamping surfaces (8) of the bearing block (2), and the clamping surfaces (7) have a sinter-roughened surface at least in some areas.

Apparatus and methods for achieving a high strength bonded joint between a stub connector and a shaft.

A resin coating layer in a sliding member has a surface shape indicated by a shape line. This shape line is divided into recessed sections and protruding sections by an average line for uneven areas. The inclination R of a straight line connecting the bottom of these recessed sections and the peak of these protruding sections is classified into Ra: R<0.02, Rb: 0.02R0.04, and Rc: 0.04<R. The sliding member comprises a resin coating layer fulfilling Ra+Rb50%.

There is provided a sliding member formed by combining a resin overlay and a soft metal overlay. The sliding member has a soft layer comprising a metallic material with a hardness of less than 40 HV provided under a resin overlay layer comprising a solid lubricant and resin. In the event of contamination by a foreign matter, the soft layer under the resin overlay layer is capable of plastic deformation and the resin overlay layer is capable of partial deformation accompanying the plastic deformation due to the hardness (T1) (m) of the soft layer and the hardness (T2) (m) of the resin overlay layer being such that 0.2T1/T27.0 and 3.0T120.0. Consequently, a foreign matter is desirably embedded and resistance to a foreign matter can be improved. Low friction is maintained by the resin overlay layer even after contamination by a foreign matter.

A thrust sliding bearing 1 includes: a synthetic resin-made upper casing 3 which has a vehicle body-side seat surface 10 for a mounting member 8 on a vehicle body side and an annular lower surface 2; a synthetic resin-made lower casing 5 on which an annular upper surface 4 opposed to the annular lower surface 2 and a spring seat surface 25 for a suspension coil spring 7 are integrally formed, and which is superposed on the upper casing 3 so as to be rotatable about an axis O of the upper casing 3 in an R direction; and a synthetic resin-made thrust sliding bearing piece 6 which is disposed in an annular gap 9 between the annular lower surface 2 and the annular upper surface 4, and has an annular thrust sliding bearing surface 51 which slidably abuts against at least one of the annular lower surface 2 and the annular upper surface 4.

A synthetic resin rolling bearing retainer is to be arranged between an inner ring and an outer ring of a rolling bearing. A plurality of guided portions protruding radially outward from an outer diameter surface of the retainer is provided along a circumferential direction of the outer diameter surface. Each of the guided portions has a guide surface protruding to be in sliding contact with the outer ring, a chamfered portion formed at an edge portion of the guide surface, and a groove portion formed at a portion of the guide surface in an axial direction. The guide surface and the chamfered portion have surface properties where an arithmetic average roughness Ra is 1.0 to 9.8 m and a maximum height Rt is 10.1 to 102.9 m. A parting line is provided radially inside the guide surface.

A bearing article can include a metal substrate having a bronze layer; a PEEK layer; a PTFE composition layer overlying and penetrating the PEEK layer. A method for preparing a bearing article can include providing a metal substrate with a sintered bronze layer, electrostatic spraying a non-fluorinated polymer onto the metal substrate followed by spraying a fluorinated polymer onto the non-fluorinated polymer and heat rolling to form a laminate.

For friction reduction in sliding bearing, it is known to structure the sliding surface (1) by ECM by introducing a plurality of microscopic small indentations (27). According to the invention it is proposed in particular in the same process step to smoothen also the intermediary spaces (6) between the indentations (27), thus to remove the tips of the surface profile.

Technology is described for an antiwetting coating attached to a substrate (e.g., metal substate) on a liquid metal container. In one example, the liquid metal container includes a first enclosure member, a second enclosure member, liquid metal, and an antiwetting coating. The first enclosure member includes a first substrate with a first surface. The second enclosure member includes a second substrate with a second surface. The first enclosure member is positioned proximate to the second enclosure member such that a gap is formed between the first surface and the second surface. The liquid metal positioned within the gap. An antiwetting coating attached to the first surface and/or the second surface. The antiwetting coating includes chromium nitride (CrN), dichromium nitride (Cr.sub.2N), chromium (III) oxide (Cr.sub.2O.sub.3), and/or titanium aluminum nitride (TiAlN) attached to the first surface and/or the second surface.
