shock absorbers and oil brakes

Development and production are carried out by SCHNETZ

Shock absorbers and oil brakes ensure reliable and smooth deceleration of moving masses. During any movement, unwanted shocks and vibrations occur, which, without proper damping or braking, can lead to rapid wear or damage to the affected system. Industrial shock absorbers reduce impacts, lower operational noise, and contribute to the sustainable protection of industrial equipment by preventing heavy impacts and excessive rebound.

hydraulic shock absorbers

Hydraulic shock absorbers are used for a variety of purposes. Our range includes a wide selection of products suitable for diverse requirements. Options range from self-adjusting shock absorbers with stroke-controlled throttle functions—offering either a rapidly increasing damping force curve with a short stroke or a gently increasing damping force curve with a long stroke—to shock absorbers with manually adjustable damping hardness.


Our products are generally suitable for linear applications, while, for instance, the DYSD shock absorber is designed for rotary applications.

Hydraulic Cushioning Cylinders

Hydraulic cushioning cylinders are the ideal choice for ensuring a slow, consistent braking speed over the entire stroke. The braking speed can be individually adjusted, allowing optimal adaptation to the specific industrial application. Slow feed speeds are possible, reaching as low as 0.1 m/s.
