The present invention provides a split inner ring for an adjustable guide blade arrangement, having a ring segment arrangement with at least two ring segments (1, 2) and a bearing bush arrangement with at least one bearing bush (5) for mounting an adjustable guide blade (4) of the guide blade arrangement, in which a ring segment and another ring segment of the ring segment arrangement can be joined together by the bearing bush arrangement.

The present invention discloses a self-lubricating fabric, a method for producing the self-lubricating fabric, and use of the self-lubricating fabric. Warp yarns or weft yarns of the fabric are composite yarns formed from fluorinated resin yarns and other yarns. The surface area of the other yarns on one surface of the fabric takes up 0 to 30% of the total surface area of the composite yarns, and the ratio of the section diameter of the other yarns to the section diameter of the fluorinated resin yarns in the composite yarns is 0.12 to 0.80. The self-lubricating fabric is characterized by low friction coefficient, excellent wear resistance property and high laminating strength, as well as simple production process, low cost and zero pollution to the environment. The fabric with low friction coefficient can be applied to mechanical moving parts, and is especially suitable for use in environment of low speed, high load and high or low temperature.

A bearing can include a generally cylindrical sidewall, a flange extending radially from the generally cylindrical sidewall, and a feature extending radially from the generally cylindrical sidewall at a location disposed a distance from the flange. An assembly can include the beating and a structure having an opening with a relief portion adapted to receive the feature.

In a method for producing a vehicle seat fitting, in which a plain bearing bush (28) is pressed in the axial direction into a receptacle of a first fitting part (11), wherein the pressed-in plain bearing bush (28) has a radially protruding securing region (28b), the securing region (28b) is formed before or after the pressing-in operation by material of the plain bearing bush (28) being displaced uncut, and the wall thickness (b) of the plain bearing bush (28) being less than 1.5 mm.

A method is provided for producing an angular bearing cage from a sleeve-like blank. In order to significantly reduce the manufacturing costs compared to known solutions even for small series, the method comprises the following steps of: Step A: providing a sleeve-like blank extending along an axis. Step B: rolling a wall section to be formed of the blank while changing the angle of the wall section to be formed relative to the axis of the blank. Step C: introducing rolling element pockets into the rolled wall section. A corresponding device and a correspondingly produced rolling bearing cage or angular bearing cage are also provided.
