About ACE Stoßdämpfer GmbH
ACE Stoßdämpfer GmbH, headquartered in Langenfeld (NRW), is a specialist in motion control solutions and belongs to the Expert Brands of the Stabilus Group. The product portfolio covers damping technology (small, industrial and heavy industrial shock absorbers, TUBUS structural dampers, SLAB shock absorption plates), speed control (gas pressure and gas traction springs, hydraulic brake cylinders, door dampers, feed oil brakes, rotary dampers), vibration technology (vibration-isolating plates, rubber-metal isolators, air spring elements) as well as safety products (safety shock absorbers, clamping elements, viscoelastic shock absorbers). Products are manufactured, among other things, from steel (tenifer hardened, hard chrome plated, zinc plated) as well as from elastomers such as co-polyester and mixed-cell PUR; damping plates are cut and finished by water jet and knife cutting, slitting, sawing and drilling. Fields of application include automation and production technology, mechanical and plant engineering, intralogistics, medical technology, agricultural machinery, shipbuilding and aircraft construction, energy technology as well as conveying technology. Since 2026, ACE has been manufacturing shock absorbers regionally in Germany to an increasing extent; customers worldwide are served via sales partners in 45 countries.
