Abstract: A plastic part, especially a bearing part, specifically a cage for receiving rolling bodies of a bearing. The body of the plastic part is essentially made of a radiation-crosslinkable plastic material. Pigments that undergo a visible change during the irradiation are mixed in with the plastic material. Also, a method is disclosed for producing a plastic part, especially a bearing part, specifically a cage for receiving rolling bodies of a bearing the plastic part that has a body made of a radiation-crosslinkable plastic material.

Abstract: A round table bearing, which has a radial, axial roller bearing for mounting a first bearing ring part relative to a second bearing ring part, and a squeeze-film damper which is connected parallel to the radial, axial bearing. The squeeze-film damper has a basic damper component which is coaxial to the bearing ring parts and which is fastened, together with a rolling element of the bearing ring part which contacts the radial, axial roller bearing, to a rotary table base part.

Abstract: A method for producing a cage of a rolling bearing, for receiving a rolling body. The body of the cage is a plastic material that can be cross-linked by radiation, and is provided with rolling bodies later during the method. The body of the cage is fitted with the rolling bodies only once the structure of the cage has been exposed to the radiation. Also, a cage is disclosed for receiving rolling bodies of a rolling bearing, which has a body consisting of a plastic material.

Abstract: The radial antifriction bearing has an outer bearing ring, an inner bearing ring and roller bodies, which are arranged between the bearing rings, are held at uniform distances from one another in the peripheral direction by a bearing cage. The roller bodies are discs that each have two parallelly arranged lateral surfaces which are symmetrically flattened from a spherical basic shape. In order to prevent edge stresses between the discs and the raceways, at least the raceway in the inner bearing ring, on its outer edge areas, transition into a logarithmically decreasing profile.

Abstract: A tensioner for a traction drive includes a cylinder arranged in a housing at a distance to a housing wall to thereby define an interior space which contains hydraulic fluid. A piston is received in the cylinder for back-and-forth movement and bounds a pressure chamber containing hydraulic fluid. The piston has a cylinder-distal end which is operatively connected to a spring-biased tension roller supported on a traction member. Formed between the piston and the cylinder is a leakage gap, and a reservoir for hydraulic fluid is provided in an area of the leakage gap to prevent ingress of air into the pressure chamber, when the traction drive is at a rest.

Abstract: The multiple-row angular contact antifriction bearing has an outer bearing ring, an inner bearing ring, and roll bodies, which are arranged at least in two rows next to one another between the bearing rings. The roll bodies are ball discs having two lateral surfaces that are symmetrically flattened from a spherical basic shape whose raceways are arranged inside the bearing rings, abutting against one another so that the respectively adjacent roll bodies of each row have their lateral surface pointing toward one another and arranged directly next to one another on a transversal axis situated at a right angle to the pressure angle axes. These lateral surfaces also provide mutual guide surfaces.
