MA30 to 900 series


ACE's MA30, MA35, MA50, MA150, MA225, MA600 and MA900 family of miniature shock absorbers can be precisely adjusted and adapted to individual requirements. For example, the MA150 is equipped with the rolling diaphragm technology of the MC150 to MC600 family and offers all the advantages of this technology, such as its use in pressure chambers. Thanks to long strokes (up to 40 mm on the MA900), reaction forces are reduced, resulting in smooth damping.

All variants of these units are ready-to-install and maintenance-free, and are equipped with an integrated fixed stop. They provide the best service when data is changing, calculation parameters are unclear or maximum flexibility of use is required.

ACE's adjustable miniature dampers can be used to adapt precisely to the customer's application and are therefore widely used in mechanical engineering and many other applications.

Capacity: 3.5 Nm/Cycle to 100 Nm/Cycle
Impact speed: 0.15 m/s to 4.5 m/s (other speeds on request)
Operating temperature : 0 °C to 66 °C
Mounting: your choice
Fixed stop: integrated
Adjustment: Hard impact at the beginning of the stroke, setting of the ring towards 9 or PLUS. Hard impact at the end of the stroke, setting of the ring towards 0 or LESS.
Materials: Outer body, accessories: Corrosion-resistant coated steel; piston rod: Stainless steel, hardened and tempered.
Damping fluid: oil, temperature stable

Note: If an accurate end position marker is required, consider the use of the type AH limit stop. The shock absorber is preset on delivery in a neutral position between soft and hard.

Safety instructions: External materials in the immediate environment can attack the sealing components and shorten the service life. Please contact us for proposals of suitable solutions. Do not paint the
shock absorbers due to heat emission.

On request: nickel plated or other special options available on special order. Models without rod stop.
