A novel steering tube assembly is provided having a steering tube with a first end and a second end. An upper plate assembly is coupled to the first end of the steering tube and a drive gear plate is coupled to the second end of the steering tube. A bearing steering tube plate is coupled to the steering tube at a location between the first end and the second end. The bearing steering tube plate has a first surface and a second surface. A bearing support is coupled to the first surface of the bearing steering tube plate and includes a cylindrical portion and a flange portion. A bearing block is coupled to the bearing support and the bearing block comprises a low-friction, non-metallic material.

A casing for a shaft assembly, a shaft assembly, a method of forming a casing, and a drive assembly. The casing may generally include a liner defining a central passage and having a body and an outwardly-extending leg (e.g., extending circumferentially about and/or axially along the body), and a cover extending circumferentially about and axially along the liner.

A slide bearing for a support mount of a motor vehicle includes a first housing part, a second housing part, and a slide bearing device arranged between the two housing parts. In embodiments, the slide bearing device includes at least a first slide body and at least a second slide body. With embodiments, at least a section of the first slide body is made of a hybrid material. A method of producing a slide body and a method of producing a slide bearing are also disclosed.

A head shaft assembly has a center tube, an end tube, a collector sprocket and a collar. The center tube has drive and driven ends. The center tube has a center tube diameter. The end tube has a key extending longitudinally along an outer surface and inner and outer ends. The key defines a key length and the end tube has an end tube diameter. The collector sprocket is mountable to the end tube and rotationally secured to the end tube by the key. The collar is hollow between a first end and a second end. The center tube diameter is substantially the same as the end tube diameter and the drive end is proximate to the inner end. The drive end and the inner end are positioned within the collar between the first end and the second end. The collar fixes the center tube to the end tube.

The present invention provides a dust cover which is provided between an engine room and the driver's seat such that, when a steering shaft provided under a steering wheel of a vehicle is installed passing through a vehicle frame, the steering shaft passes through the dust cover. The dust cover is characterized by comprising: a pair of bearings coupled to the steering shaft; a pair of bearing races provided to surround outer circumferential surfaces of the bearings; a ring-shaped fixing cap forcibly inserted into the bearing races through both sides of an opening by interference fitting, thereby fixing the bearings; and an integrally formed seal part having through-holes to which the bearing races are coupled.

The present invention achieves a high mechanical load capacity of a rod end by means of a component loop that passes around a bearing, where the component may be made of continuous-fiber reinforced composite material with thermoplastic matrix and where the continuous-fiber reinforced composite material with thermoplastic matrix may extend into a threaded stem of the rod end, and the component made of continuous-fiber reinforced composite material with thermoplastic matrix may be enclosed by short-fiber reinforced, long-fiber reinforced, or unreinforced thermoplastic. The threaded stem can be implemented with an external or an internal thread.

To provide a non-oil-impregnated sliding bearing having superior low friction capable of suppressing an increase of a shaft temperature in a continuous use, and a bearing apparatus and an image forming apparatus provided with the sliding bearing. Sliding bearings 5a to 5c support rotation shafts on cylinder inner surface in a rotatable manner. Each of the sliding bearings 5a to 5c is formed of a molded member of a non-oil-impregnated resin composition that does not contain oil. The resin composition contains an injection-moldable ultrahigh molecular weight polyethylene resin as a base resin, a polytetrafluoroethylene resin as an additive, and an acicular inorganic filler having Mohs hardness of 3 or less. The resin composition contains 65 vol % or more of the ultrahigh molecular weight polyethylene resin, 5-25 vol % of the polytetrafluoroethylene resin, and 1-20 vol % of the acicular inorganic filler, based on the whole of the resin composition.

A greaseless pivot center swivel and bearing device is provided. The device includes an outer housing having a sidewall with top and bottom portions, a top plate coupled with the top portion that includes an opening therein, and a bottom plate coupled with the bottom portion that includes an opening therein. The sidewall cooperates with the top and bottom plates to define an interior volume. A plurality of bushing members formed of a low-friction material are positioned within the interior volume and include a surface cylindrically curved about an axis extending between the top and bottom plates of the housing. The cylindrically curved surfaces cooperate with the openings in the top and bottom plates to define a cylindrical passage through the interior volume sized and shaped for receiving a cylindrical tube that rotates therein, e.g., a tube configured to connect with a water supply column of a mechanized irrigation system.
