A bearing and seal arrangement for joints in heavy duty vehicles includes two spherical bearing each having an outer ring surrounding an inner member with lubricious liner disposed therebetween. One of the spherical bearings has a seal receiving area having an axially extending width that is greater than that of the other spherical bearing. The spherical bearings are aligned coaxially with one another. One seal receiving areas has a flexible double lipped annular seal and a scraper seal positioned therein. The scraper seal is positioned axially outward from the flexible double lipped annular seal. The other seal receiving area has a boot seal positioned therein.

Bottom bearings may be configured to bear the weight of a vertical shaft. In some implementations, a bottom bearing may include a first half-cylinder including a first shoulder and a first inside surface. The bottom bearing may also include a second half-cylinder including a second shoulder and a second inside surface. The first shoulder and second shoulder are configured to bear the weight of the vertical shaft by exerting an upward force on a sleeve affixed to the vertical shaft. A method of manufacturing a bottom bearing may include the steps of forming a cylinder from an ultra-high-molecular-weight (UHMW) polyethylene, wherein the cylinder includes a shoulder, an inside surface, and a central axis. The method may further include cutting the cylinder along the central axis to form the first half-cylinder and the second half-cylinder.

A kit of replacement parts and a method are used to replace a roller on a defective pin including a washer and a retaining pin. The invention is particularly useful in conjunction with roll-off trucks and trailers. The method includes the steps of removing the retaining pin, washer and roller from the defective pin, placing a new sleeve over the defective pin, placing a new roller over the new sleeve, placing a new washer over the sleeve, and installing a new retaining component to maintain the position of the new sleeve, roller and washer. In accordance with one embodiment, the new retaining component is a retailing pin used to replace an old retaining pin. According to an alternative embodiment, the new retaining component is a snap retaining ring. The sleeve is preferably hardened, and the defective pin may have a nominal O.D. of 2 inches.

A slide-bearing assembly capable of enabling sliding of a load-carrying surface relative to a load-supporting structure, such that the slide-bearing assembly may include a first arrangement of at least one substantially nonmetallic elongate bearing element capable of extending along a first load-carrying surface and a second arrangement of at least two substantially nonmetallic elongate bearing elements capable of extending longitudinally in series along a second load-carrying surface parallel to the first load-carrying surface such that the second load-carrying surface is in non-coextensive supportive relationship with the first load-carrying surface.

The socket assembly includes a housing with an inner bore which extends along an axis from a first end to an second end. A ball portion of a ball stud is received in the inner bore, and with a shank portion of the ball stud projects through the second end. A backing bearing is disposed in the inner bore and has a bearing surface which is in surface-to-surface contact with an outer surface of the ball portion for enabling relative rotation between the housing and the ball stud. The backing bearing also has a lubricant opening which extends therethrough and a plurality of lubricant wells which are spaced around the bearing surface from one another for holding a lubricant. The backing bearing lubricant grooves which are formed into the bearing surface and extend from the lubricant opening to the lubricant wells for filling the lubricant wells with lubricant.

One aspect of the disclosure relates to a sliding member. The sliding member includes: a first sliding portion having a first lubricant placed between first parts of a first friction sliding mechanism; and a second sliding portion having a second lubricant placed between second parts of a second friction sliding mechanism. The first sliding portion has a lubricant feed port from which the first lubricant is fed, and the second sliding portion has no lubricant feed port from which the second lubricant is fed. The first lubricant contains base oil and an additive. The second lubricant contains base oil and an additive containing conductive carbon. The second lubricant contains a relatively larger amount of conductive carbon than the first lubricant.

A trunnion bearing includes an inner ring having exterior and interior surfaces; and an outer ring having interior and exterior surfaces. A portion of the inner ring is disposed in the outer ring. A lubricious liner is disposed between the inner ring and the outer ring. The trunnion bearing includes a bushing disposed in the inner ring. The bushing has a lubricant reservoir formed therein to dispense a lubricant therefrom.

Bottom bearings may be configured to bear the weight of a vertical shaft. In some implementations, a bottom bearing may include a first half-cylinder including a first shoulder and a first inside surface. The bottom bearing may also include a second half-cylinder including a second shoulder and a second inside surface. The first shoulder and second shoulder are configured to bear the weight of the vertical shaft by exerting an upward force on a sleeve affixed to the vertical shaft. A method of manufacturing a bottom bearing may include the steps of forming a cylinder from an ultra-high-molecular-weight (UHMW) polyethylene, wherein the cylinder includes a shoulder, an inside surface, and a central axis. The method may further include cutting the cylinder along the central axis to form the first half-cylinder and the second half-cylinder.

A Suspension Bearing Lubricating System, lubricating moving parts engaging with pivoting suspension component bearings used in street motorcycles, dirt bikes, all-terrain vehicles and various other machines. The Suspension Bearing Lubricating System comprises of a bolt hollowed internally and capped with a grease fitting (or form of lubrication receptacle) or a bolt which is hollow at both ends but solid in the center and a specialized bushing allowing for the flow of grease. Lubricant will be inserted via a lubricant receptacle; lubricant will travel into the bolt then out of holes in the shaft of the bolt which will allow passage of lubricant into bushing if applicable. Once lubricant reaches specialized bushing it will travel into integrated grooves to holes in the bushing then out, directly in contact with the suspension component bearings.

Provided is a slide bearing of lower cost that is capable of preventing the intrusion of dust, muddy water, etc. and has good sliding performance. In a ring-shaped space (5) formed by assembling an upper case (2) with a lower case, a ring-shaped outer dust seal part (42), which bends with one end (420) contacting the upper case (2) and the other end (421) contacting the lower case, is disposed on the outside of a ring-shaped thrust bearing part (40), and the outer dust seal part (42) is connected to the thrust bearing part (40) by connecting parts (43) that extend radially outward from the outside of the thrust bearing part (40), integrating the two as a dust seal-integrated center plate (4). Disposed between the thrust bearing part (40) and the upper case (2) is a ring-shaped lubrication sheet (6), which has surfaces (62, 63) that slide on the mating surfaces facing same.
