Abstract
In a cylinder for a hydraulic system, a seal has a sealing bead clamped between a housing of the cylinder and a supporting part which holds the sealing bead in a deformed state by pretensioning. The seal is reliably held in its intended position by the supporting part and, therefore, pressure fluctuations in the pressure space do not cause a relative movement of the seal and wear of the sealing bead.
