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 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.
