A semicircular tube-shaped bearing has a bearing main body formed from a resin, an inner circumferential surface that slides over an opposing shaft, and an outer circumferential surface contacting a housing. The semicircular tube-shaped bearing may have a laminated structure including a resin layer and includes at least a portion of the inner circumferential surface, and a reinforcing layer that is in close contact with the resin layer. In this case, the bearing main body has a resin layer that includes the inner circumferential surface, and a reinforcing layer that is in close contact with the resin layer. The reinforcing layer has a higher rigidity than the resin layer, and raises the rigidity of the resin layer by being in close contact with the resin layer. The material forming the reinforcing layer is a metal such as iron, aluminum, or stainless steel.

An end fitting connector assembly includes an end fitting having a first end, a second end and a through opening that extends in a direction that is transverse to an end fitting axis extending through the first and second ends and in which the through opening is defined by a peripheral wall. An elastically deformable race fitted into the through opening of the end fitting includes an exterior surface that engages the peripheral wall and an interior surface configured to provide snap fitting engagement with a spherical ball mount. At least one feature retaining the race within the end fitting creates an increased disassembly force, which may prevent disassembly without employing a release tool or release feature. The interior and exterior surfaces of the race can include spherical surfaces for conforming to the spherical ball and the peripheral wall of the end fitting.

A bearing device includes a first bearing for a first roller; a second bearing for a second roller; a bearing holder for the first and second bearings, wherein when the first bearing is mounted in the holder, a peripheral surface of the first roller is projected out of the holder through an opening of the holder, and the second roller is provided in the second bearing contacting the first roller in the holder; a contact portion for determining a relative position between the first and second bearings by contacting the first bearing with the first bearing mounted in the holder; and a moving mechanism for moving the second bearing toward the opening with dismounting of the first bearing, and for holding the second bearing in a position in which at least a part of a peripheral surface of the second roller projects out of the holder through the opening.

A sliding element with one substrate and at least one layer of a sliding layer material applied to the substrate is described. The sliding layer material can consist of a sliding coating with at least one cross-linkable bonding agent or at least one high-melting thermoplastic material or which consists of a material with a matrix of at least one high-melting thermoplastic material or at least one duroplastic material. This sliding layer material contains Fe.sub.2O.sub.3 with a preferred proportion 0.1 to 15% by volume.

A split bearing cage for a rolling-element bearing assembly includes a first bearing cage segment and a second bearing cage segment each having two side ring sections axially spaced apart by a plurality of bridges. Adjacent pairs of the bridges define rolling-element receiving pockets for receiving rolling elements of the rolling-element bearing assembly and for holding the rolling elements spaced apart from each other and for guiding the rolling elements. The first bearing cage segment is connected to the second bearing cage segment via a swivel joint that may be formed of a bolt element on a first end of the first bearing cage segment and an at least partial eyelet on the first end of the second bearing cage segment.

A driveshaft assembly for a compressor includes an unloader assembly and a driveshaft. The unloader assembly includes an unloader and a counterweight. The unloader assembly is rotationally supported by a bearing. The unloader includes a flank surface that is slidably engaged with a flank surface on the driveshaft.

A engine connecting includes a large diameter end portion mounted to a crank of a crankshaft of an engine to be rotatable, a small diameter end portion into which a piston pin is inserted and which supports the piston pin to be rotatable, and a connecting portion connecting the large diameter end portion and the small diameter end portion at a longitudinal end portions thereof. The connecting portion has a plate-shape widened in a wide width direction thereof to be perpendicular to a center axis of the crank shaft, the connecting portion is provided with four vertical reinforcing portions projecting in four directions so as to extend in a longitudinal direction of the connecting rod from the small diameter end portion to the large diameter end portion.
