A linear guide mechanism includes a housing having an inside housing surface that defines a bore extending through the housing coaxial with a longitudinal axis. A shaft is disposed at least partially in the bore and is reciprocatably and linearly moveable in the bore along the longitudinal axis. The shaft has an exterior shaft surface. A self-lubricating liner is disposed in the bore between the inside housing surface and the exterior shaft surface. The self-lubricating liner has an inside liner surface that is in sliding engagement with the exterior shaft surface of the shaft. The self-lubricating liner has an exterior liner surface.

A bearing laminate can include a metal support layer, a foam layer overlying the metal support layer, the foam layer including a polymeric foam; and a sliding layer overlying the polymeric foam layer, the sliding layer comprising a polymer matrix. Bearing articles made from the bearing laminate can have exceptional damping properties, such as a high damping ratio combined with a low dynamic stiffness.

A sealing device for a bearing unit that includes an inner ring, an outer ring, a plurality of rolling bodies interposed between the inner ring and the outer ring, the sealing device having a radially outer anchoring portion, an intermediate portion, and a radially inner sealing portion distal to the radially outer anchoring portion, the sealing device being made of a single polymer plastic material.

A pillow block assembly for a sand and/or salt spreader includes a housing having a central body and two mounting flanges disposed on opposing sides of the central body, the mounting flanges extending outwardly from the central body, the housing being composed of PBT or a PBT-based composite, the housing having a bore which extends through the central body in a transverse direction; and a bearing positioned within the bore, the bearing includes at least one ball bearing or at least one roller bearing, the bearing being composed of stainless steel and configured to receive a spinner shaft of the sand and/or salt spreader. The PBT or PBT-based composite housing is mountable within an interior of a chute of the sand and/or salt spreader via the mounting flanges.

A ball socket assembly, bearing therefor, and method of construction thereof are provided. The ball socket assembly includes a housing with an inner bore extending between a closed first end region and an open second end region. A fiber-reinforced bearing is disposed in the inner bore. The bearing has a lower portion presenting a lower bearing surface having a first radius of curvature and an upper portion presenting an upper bearing surface having a second radius of curvature that is greater than the first radius of curvature. The lower bearing surface and the upper bearing surface surround a ball cavity in which a spherical ball portion of a ball stud is disposed. The housing second end region is plastically deformed radially inwardly to impart a bias on the bearing upper portion to fix the bearing and the ball portion in the housing. The bias causes the second radius of curvature to be biased substantially equal to the first radius of curvature.

This assembly includes a ball joint assembled in a casing, and receiving an axle capable of sliding and/or rotating therein. The ball joint is formed from the winding of a fabric of small thickness ranging between 20 μm and 150 μm and mixed with a resin comprising fillers. The fabric has the form of strips having a width ranging between 5 mm and 200 mm; the strips being crossed in several layers.

A gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a compressor section, a combustor section, a turbine section, and at least one rotatable shaft. The engine further includes a seal assembly including a seal plate mounted for rotation with the rotatable shaft and a face seal in contact with the seal plate at a contact area. The seal assembly includes an abradable coating adjacent the contact area, and the abradable coating includes magnetic particles.

Provided is a sliding bearing capable of reducing the number of components and reducing costs. This sliding bearing (1) is provided with; an upper case (2); a lower case (3) combined with the upper case (2); and an annular dust seal-integrated center plate (8) that has a dust seal part (6) for covering a gap between the upper case (2) and the lower case (3), is disposed between the upper case (2) and the lower case (3), and enables relative rotation between the upper case (2) and the lower case (3). The dust seal-integrated center plate (8) is integrally formed with the lower case (3).

A thrust bearing having an inner cage having inner cage pockets, with inner rollers in the inner cage pockets, and a first outer cage having a larger diameter than the inner cage and having first outer cage pockets, with first outer rollers in the first outer cage pockets. The inner cage and the first outer cage are axially and radially aligned. A radially extending rim is provided on one circumferential side of one of the inner cage or the first outer cage that faces a facing circumferential side of the other of the inner cage or the first outer cage. First and second radially extending side tabs are provided on the facing circumferential side of the other of the inner cage or the first outer cage that define a circumferentially extending channel therebetween that receives the radially extending rim to connect the cages together.
