Abstract
A piston assembly includes a body and a piston. The body has a first cylindrical cavity. The first cylindrical cavity has an inner wall and a diameter. The piston is shiftably guided in the first cylindrical cavity. The piston has a piston sealing which is arranged at the piston. The piston sealing seals the piston against the inner wall of the first cylindrical cavity and generates sealing forces in a radial direction. The inner wall of the first cylindrical cavity absorbs the sealing forces. The piston sealing is arranged to be stored free from the sealing forces until the piston assembly is used.

A piston assembly comprising:
- a body comprising a first cylindrical cavity, the first cylindrical cavity comprising an inner wall and a diameter;
- and
- a piston which is configured to be shiftably guided in the first cylindrical cavity, the piston comprising a piston sealing which is arranged at the piston, the piston sealing being configured to seal the piston against the inner wall of the first cylindrical cavity and to generate sealing forces in a radial direction,
- wherein,
- the inner wall of the first cylindrical cavity is configured to absorb the sealing forces, and
- the piston sealing is arranged to be stored free from the sealing forces until the piston assembly is used.
A tribological system comprising:
- two bodies which rub against each other in a contact range,
- wherein,
- at least one of the two bodies comprises, at least in the contact range, a thermoplastic elastomer or a thermoplastic material,
- the thermoplastic elastomer or the thermoplastic material comprises a paraffin, and
- the at least one of the two bodies is stored in air or in an oxygen comprising gas so that the paraffin moves to a surface of the at least one of the two bodies.
