Abstract: Disclosed is a casting mold comprising at least two adjoining molds that enclose a hollow space, the cavity, which is accessible from the outside via at least one inlet duct and into which liquid casting material can be injected or pressed, and at least one vent opening that extends from the cavity to the outer surface of a mold, points approximately in the direction in which the hardened cast part is removed from the mold, and is closed by a pin-type breather. The face of the breather facing the cavity is perforated by small air holes which are permeable to air while retaining the liquid casting material and which are connected to the outer surface of the breather.

Abstract: Roller bearing with a segmented cage for guiding the roller bodies, said cage comprising an inner ring on which a plurality of roller bodies can roll, and which can also roll on an outer ring which is concentric to the inner ring, a cage consisting of a plurality of webs which are distributed in a uniform manner over the periphery and which are aligned so as to be parallel to each other and to the longitudinal axis of the cage, and a plurality of lateral plates for joining the webs, two webs and two lateral faces being firmly connected to one another to form a cage segment, which forms a pocket for guiding a roller body and all cage segments are connected to one another in pairs to form an inherently closed cage.
