Industrial shock absorbers are maintenance-free, ready to install hydraulic components. They have an integrated fixed stop. The adjustable version enables precise adjustment to the desired dampening level. After installation, operate and adjust the shock absorber a few times until the desired braking level is achieved. Exceeding the max. energy intake per hour is possible if temporarily disconnected or the shock absorber is cooled with cylinder exhaust air. The installation position is arbitrary.

Individual filled gas springs are excluded from replacement. Gas springs are maintenance-free, self-contained systems that are filled with nitrogen under high pressure. For end-of-travel damping and lubrication, a defined amount of oil is also contained inside. The gas springs contain a nonreturn valve in a threaded pin on the pressurised pipe, which allows the pushing force to be lowered at a later time. Gas pressure springs in the sizes 04/12 and 06/15 must be stored and installed with the piston rod extending downwards. As of size 08/19, storage and installation in any orientation is possible. Keep in mind, however, that end-of-travel damping is effective only when the piston rod extends downwards. As a consequence of the physical properties when filling a gas spring, a tolerance range of ±5 % results for the rated pushing force. Gas springs are filled with nitrogen under high pressure and under no circumstances should they be opened or overloaded.
