Abstract: A bearing unit (1) for a suspension strut (2) of a motor vehicle (3), has at least the following components: a guide ring (4) having a guide axis (5) for a wheel spring (6); a cap (7) with a damper holder (8) for a damper block (9); a bumpstop holder (10) for a bumpstop (11); an axial bearing (12) with a bearing pitch circle (13) for supporting the guide ring (4) on the cap (7) and for low-friction rotation about the guide axis (5) relative to the cap (7). The bumpstop holder (10) is formed integrally by the cap (7).

Abstract: A method of heat treatment of wire including cooling the wire stock immediately after the stock leaves the rolling heat region to a temperature below the starting temperature of martensite formation and, thereafter, forming wire coils.

Abstract: A method of cooling steel sections which are hot from rolling by means of shock-like cooling following the rolling process so as to form a martensitic surface layer, and by subsequently autogenously tempering this surface layer by means of core heat to obtain a tough-resistant structure with an austenitic remaining cross-section, wherein the method is used in connection with types of steel which, with uncontrolled cooling in air, would directly transform from the austenitic phase into martensite because of their alloying elements from the group Cr, Mn, Mo, Ni and other suitable elements.
