Abstract: A plain bearing arrangement for a shaft loaded with a circumferential radial force, having a bearing ring arranged in a rotationally fixed manner in a housing component and having a first running surface formed on the inner circumference, and a second running surface formed on the outer circumference of the shaft or on the outer circumference of a sleeve arranged on the shaft, the second running surface being mounted in a sliding manner on the first running surface, wherein a device for axially feeding a lubricant to an end side of the shaft is provided, and at least one axially extending, radially open groove that is axially open in a direction of the end side of the shaft is formed in the second running surface.

Abstract: A plain bearing assembly of a rotational element on a bearing pin, the assembly including a bearing bolt, a bearing sleeve, which is non-rotatably mounted on the pin and which has a first bearing surface formed on its outer circumference, a rotational element which is rotatably mounted on the bearing sleeve and which has a second bearing surface that is formed on its inner circumference and that is slidingly mounted on the first bearing surface. The bearing pin has at least one lubricant channel opening onto the outer side of the pin and the bearing sleeve has a radial groove formed on its inner circumference, which groove communicates with the radial lubricant channel, and at least one opening branching off radially from the radial groove and opening towards the rotational element. The rotational element has a radial groove formed on its inner circumference and communicating with the opening and the first bearing surface is harder than the second bearing surface.

Abstract: A slip-free rolling bearing (1) is provided, in the outer ring (3) of which there is formed an encircling groove (7). The rolling bodies (2) of this rolling bearing are surrounded, in the manner of an envelope circle, by a central ring (8) and are in physical contact therewith. To ensure permanent drive of the rolling bodies, the central ring is inserted into the groove so as to be radially free but is fixed rotationally fixedly in said groove, wherein a radial depth of the groove is greater than a thickness of the central ring. The rotational fixing of the central ring in the groove of the outer ring is effected by a spring element.

Abstract: A locking unit of a camshaft adjuster (1) for an internal combustion engine is provided, in which a locking pin (19) establishes a positive connection between a driving element and a driven element of the camshaft adjuster (1). The driving element and/or the driven element are formed by a plastic part. An insert (26) against which the locking pin (19) rests and which is supported relative to the plastic part in the area of an inner and outer contour is inserted into the plastic part. Providing large area support of the contours makes it possible to use plastic as a material in spite of the great stress that occurs, particular attention being paid to a good introduction of force into the plastic part.

Abstract: A lip-type shaft seal is made of elastic material with a Shore A hardness of ≦75, includes a radial sealing lip, which has a sealing edge to bear against a rotating component and terminates in a axial sealing lip, which has a sealing edge to rests in installed state against a contact surface. The axial sealing lip extends at an angle of ≧35° in relation to a symmetry axis of the shaft seal, when the axial sealing lip has not been installed yet and is under no tension, and extends from the sealing edge of the radial sealing lip at a length of ≧1.4 mm. When the shaft seal is installed, the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm.
