ACE Miniature Shock Absorbers self-adjusting

Self-Compensating
Energy capacity 0.68 Nm/Cycle to 9 Nm/Cycle
Stroke 4 mm to 10 mm
Ideal for compact, efficient designs: The MC5 to MC75 series impresses users with their reduced dimensions and their very short overall lengths and low resetting forces after braking.
The outer body of each damper, produced from one solid piece, are filled with temperature stable oil, offer a continuous thread incl. a supplied lock nut and also have an integrated positive stop. These hydraulic machine elements from ACE, are ready for immediate installation and are maintenance-free. A comprehensive range of energy absorption with a wide range of effective weight potential are further benefits in these minature units.
These miniature shock absorbers are perfectly suited to use in applications such as mechanical engineering, medical and electro-technology and robotics.

Self-Compensating, Rolling Diaphragm Technology
Energy capacity 20 Nm/Cycle to 136 Nm/Cycle
Stroke 12 mm to 25 mm
Tried-and-tested and durable: Due to a hermetically sealed rolling diaphragm in each absorber, the MC150 to MC600 product family is suitable for an exceptional high lifetime of use with up to 25 million cycles. The rolling diaphragm technology perfected by ACE ensures complete separation of the damping fluid from the surrounding air. This makes direct installation in a pressure chamber e.g. as end stop damping in pneumatic cylinders up to approx. 7 bar possible.
The rolling diaphragm also benefits the very low return forces of these maintenance-free, ready-to-install absorbers. Progressive energy capacities, with a wide range of effective weight potential make these miniature shock absorbers, complete with an integrated positive stop a winner. Furthermore, the use of a side load adapter allows impact angles of up to 25°.
Miniature shock absorbers capable of universal mounting even inside a cylinder and also available in stainless steel options. They are often used in mechanical and plant engineering, and a multitude of other applications.

• Energy capacity: 20 Nm/Cycle to 136 Nm/Cycle
• Impact velocity range: 0.06 m/s to 6 m/s. Other speeds on request.

Self-Compensating, Stainless Steel, Rolling Diaphragm Technology
Energy capacity 20 Nm/Cycle to 136 Nm/Cycle
Stroke 12 mm to 25 mm
Brilliant in every respect: These high performance miniature shock absorbers in stainless steel are based on the MC150 to MC600 product family and its proven damping technology. This means that these special absorbers offer all of the benefits of the MC standard units such as the proven ACE rolling diaphragm technology for maximum service life and direct installation in a pressure chamber with up to approx. 7 bar.
Thanks to perfectly progressive maximum energy absorption and effective weight potential, their use is augmented even further by the outer body and a complete range of accessories made of stainless steel (material 1.4404).
Miniature shock absorbers made of stainless steel are mainly used in medical and electro-technology, but also in shipbuilding, packaging and chemicals industry and in the food processing. For the latter, they are filled with a special oil in order to fulfil the authorisation conditions (NSF-H1) for this market.
