Abstract: A system includes a component to be machined, the component having a plastic base body having an outer diameter and a longitudinal axis and at least one clamping auxiliary structure, and a clamping element configured to clamp the component using the clamping auxiliary structure. The clamping element includes at least one clamping jaw having at least one counter-clamping auxiliary structure that is configured to engage the clamping auxiliary structure and to fix the component in an interference-fit manner in the axial direction with respect to the clamping element. Also a machining method using the system.

Abstract: A device for holding a workpiece that includes a first clamping element and at least one second clamping element, wherein the first clamping element and the second clamping element each include on an end side extending in a radial plane a first engagement structure and at least one second engagement structure at different radial positions configured to engage at a first time an end side of a first workpiece having a first diameter and at a second time an end surface of a second workpiece of a second diameter different than the first diameter for holding the workpiece by moving the first clamping element and the second clamping element in the radial direction.

Abstract: A self-aligning roller bearing having inner and outer bearing ring elements and at least one row of roller elements disposed in between. The inner bearing ring element having a retaining flange provided on a first axial side of the roller bearing being configured for preventing the roller elements from falling out from the roller bearing. The roller bearing having a first sealing ring element located at the first axial side for sealing the first axial opening, the first sealing ring being rotatable in relation to the inner bearing ring and seals against a sealing mating surface of the inner bearing ring. The retaining flange has at least one filling slot configured for allowing the roller elements to be inserted in-between the inner and the outer bearing ring elements during assembly of the roller bearing, and the sealing mating surface being axially outside the at least one filling slot.

Abstract: A device for selectively moving a first or second tool relative to a workpiece on a lathe, the device including a first and a second tool providing system, each of the tool providing systems including a guide rail having a length direction, a slide slidably mounted on the guide rail, the slide being shiftable from a waiting position to a work position, a tool retainer on the slide, a block fixed relative to the guide rail, a first lever pivotably mounted to the block, a second lever having a first end pivotably mounted to the block and a second end pivotably mounted to the slide, and a linear actuator having a rod pivotably connected to the first lever, the rod extending in a direction not parallel to the length direction of the guide rail and being shiftable from a first position to a second position.

Abstract: A seal assembly includes a base body having a seal element and a retainer radially spaced from the seal element. The retainer includes a support surface facing the seal element, and a support ring abuts on the support surface of the retainer. The support ring has a first end and a second end circumferentially spaced from the first end, and a portion of the first end extends into a recess of the second end to connect the first end to the second end. Also a method of manufacturing the seal assembly.
