A friction bearing composite material comprises a metal base layer, a porous support layer applied thereto, and a low friction layer made from PTFE forming a bearing surface for a bearing partner. The low friction material forming the sliding surface also fills the pores in the support layer and comprises at least 60 vol. % PTFE and 10-25 vol. % zinc sulphide. In order to achieve a high wear resistance with a low coefficient of friction, the low friction material further comprises 1.5-3.5 vol. % carbon fibers and 1-7 vol. % PFA.

Friction bearing composite material with a metal base layer

A hinge housing has a flange bearing bush pressed into a transverse bearing opening. A bearing pin is swively inserted in the flange bearing bush. The plain bearing is a ready-to-install unit in that the cylindrical bush part of the flange bearing bush inserted in the bearing opening is deformed radially outwards and radially inwards by axially upsetting the front face and rests on the inner wall of the bearing opening and against the circumferential surface of the bearing pin without play. The front face is recessed behind the surface of the hinge housing part. One side of the plain bearing has an axial bearing element that exteriorly rests radially against the surface area of the hinge housing part surrounding the bearing opening and radially interiorly against an axial step of the bearing pin. The bearing pin is secured in a position in the axial direction.

Plain bearing

The invention relates to a slide bearing comprising with a bearing opening ( ) pertaining to a hinge-housing component ( ) and a flange bearing box ( ) pressed into said bearing opening ( ), whereby a bearing pin ( ) can be inserted and rotated therein. Said flange bearing box ( ) has a crimped projection ( ) which projects radially inwards in the direction of the periphery. In order to create a slide bearing which can be preassembled, said slide-bearing is formed such that said crimped projection ( ), when viewed from a longitudinal section of the box forms as a curved region ( ) in the wall of said flange bearing box ( ) in the vicinity of the axial end of the bearing opening ( ) and said curved region ( ) projects into the flange ( ) of the box ( ) in such a way that a space (h) is created between the opening ( ) and of the bearing outer side which faces the flange bearing box ( ) in the region of the curved profile prior to insertion of the bearing pins ( ). The curved region ( ) of the flange bearing box ( ) can be radially deformed radially in an outward direction.

Slide bearing and method for the production thereof

A wrapped plain bearing bush having a bush width which varies in the peripheral direction. The bush is characterized in that it is wrapped from a strip-shaped band section which is provided with a variable over the length of the section while still in its flat state and which is wrapped in such a way that the wrapped bush does not need to be subjected to any further cutting of the width; but, instead, has its definitive, variable bush width after wrapping on the bush mold.

Wrapped plain bearing bush

A roll-formed sliding surface bearing bushing is circular in an installed state and has a butt joint which extends throughout the width of the bushing and is closed in an installed state. To ensure a backlash-free bearing arrangement, the bushing has on its outside peripheral surface a trapezoidal profile, which includes an angle of 1.degree. to 30.degree. with the plane which contains the longitudinal axis of the bushing.

Roll-formed bushing for sliding surface bearings

In order to improve a bush-like antifriction bearing element for mounting a shaft, a pivot or other revolving component so that penetration of dirt into the bearing as well as out of the bearing, the antifriction bearing element is made pot-shaped so that the end of the antifriction bearing element remote from the end for insertion of the shaft, the pivot or the like, is defined by a bottom portion.

Bush-like antifriction bearing element

A sliding surface bearing for two components of a planar swivel joint for doors and flaps, which are contacting each other and are connected by a bolt, consists of a sliding material clamped into the bore of a component with press fit. To avoid the abrasion of lacquer a collar bushing is provided on both sides of the bore.
