An improved design and method is disclosed that uses a novel nesting linear slide which incorporates machine tool slides or ways into a structural member. The design simplifies the fabrication and assembly of components requiring accurate sliding alignment, such as milling machine bases, saddles, tables and columns. Due to the use of the single piece, which replaces multiple pieces in the prior art, fabrication and assembly costs are also significantly lower. The invention also enables a method of construction utilizing the novel single shape component which simplifies the assembly of machines requiring sliding surfaces with accurate alignment. The invention essentially comprises a single structural element that includes both male and female sliding members. By nesting two of the single structural elements it is possible to create sliding joints for machine tool bases, saddles, tables, and columns, as well as a wide variety of other sliding joints, in an extremely cost-effective manner. The linear slide includes a deformable element that allows for accurate alignment with no play and creates a strongly supported sliding joint.

A bearing assembly for a cam follower assembly for a ram assembly for a metal can production necker includes two or more bearings. Each of the bearing includes an inner ring positioned within an outer ring and a plurality of rolling elements positioned therebetween. The bearing assembly includes a tire press fit on the outer rings of the bearings. The tire has an elongate body portion that extends between a first radially inward projecting shoulder and a second radially inward projecting shoulder. A radially inward facing surface extends between the first radially inward projecting shoulder and the second radially inward projecting shoulder. The first radially inward projecting shoulder extends further radially inward than the second radially inward projecting shoulder.

A turbomachine having an axial stop member arranged to restrain axial movement of a bearing assembly of the turbomachine, the axial stop member having a bore defined by a radially inner surface of the axial stop member which forms a close radial fit with a shaft of the turbomachine, or a member mounted on the shaft to rotate with the shaft, an anti-rotation formation engageable with a complimentary formation provided on an outer race of the bearing assembly so as to rotationally fix the outer race relative to the axial stop member and wherein the axial stop member further comprises a lubricating fluid directing member and a lubricating fluid outlet, the lubricating fluid directing member being arranged to receive lubricating fluid that is flung radially outward from said axis, due to the rotation of the shaft, and to direct the lubricating fluid to the lubricating fluid outlet.

An exhaust-gas turbocharger (1) with a bearing housing (2), a bearing cartridge (8) inserted into the bearing housing (2), a shaft (7) which is mounted in the bearing cartridge (8) and which extends in an axial direction, a bearing housing cover (9) which is connected to the bearing housing (2), a turbine wheel (5) which is arranged on the shaft (7), and a compressor wheel (6) which is arranged on the shaft (7), wherein the bearing housing cover (9) is connected directly to the bearing cartridge (8) in order to secure the bearing cartridge (8) in the axial direction and against rotation.

A bearing housing may include a main body integrated with a bearing receiving portion. A bearing retention stop may extend from the main body and include a plurality of access cutouts for facilitating the removal of a bearing from the bearing housing without causing damage to the bearing.

A bearing structure includes: a bearing hole formed in a bearing housing, a semi-floating metal bearing accommodated in the bearing hole and having a pin hole formed therein; a through-hole formed in the bearing housing and facing the pin hole in the semi-floating metal bearing; a regulating member which is inserted into the through-hole and in which a fixed portion is pressed onto an inner surface of the through-hole for the regulating member to be fixed to the bearing housing at a fixed position where a distal end portion is inserted into the pin hole; a regulating hole opened at a base end in the insertion direction of the regulating member and extending at least to the fixed portion toward the distal end side; and a pressing member provided in the regulating hole to expand the regulating hole by pressing an inner surface of the regulating hole.

A shaft assembly includes a yoke. The yoke defines a first bore and a second bore. The first bore extends from a first face towards a second face along a first axis. The first bore has a key that extends towards the first axis. The second bore extends from a third face towards a fourth face along a second axis that is disposed transverse to the first axis. The third face and the fourth face each extend between the first face and the second face.

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.

Provided is a journal foil air bearing for supporting a load applied along a radial direction of a rotating shaft rotating about a centerline, the journal foil air bearing including a first top foil disposed to face an outer circumferential surface of the rotating shaft and surround the rotating shaft, a second top foil disposed to surround the first top foil, a bump foil provided as an elastically deformable member and disposed to surround the second top foil, a base foil disposed to surround the bump foil, and at least one separation preventer provided on the first top foil to restrain the first top foil from being separated along a longitudinal direction of the rotating shaft, wherein the separation preventer protrudes a preset length toward the second top foil and is restrained by the second top foil from moving in the longitudinal direction of the rotating shaft. According to the present invention, because the first top foil does not escape in the longitudinal direction of the rotating shaft during operation, the performance of the bearing may not be reduced and serious secondary damage due to the contact between the escaped first top foil and other components may not be caused.

A cam follower assembly includes a ball bearing having an outer ring and an inner assembly which includes two or more segments. The inner assembly is disposed in the outer ring with a full complement of balls disposed therebetween. The outer ring and inner assembly each include a race having a gothic arch cross sectional configuration that causes the balls to roll on two portions of each race.
