A sealing arrangement on piston rods with a rod guided in a cylindrical compressed-gas space, particularly on piston rods of high-pressure pneumatic springs or gas-filled shock absorbers, with at least one seal disposed on the piston rod for sealing the compressed-gas space toward the outside, with a guide for the piston rod and with a lubricant space. The lubricant space is provided with an insert that is capable of absorbing the lubricant in sponge-like fashion.
