Industrial Shock Absorbers
MA4525EUM

High energy absorption and progressive adjustment

Adjustable
Energy capacity 425 Nm/cycle
Stroke 23.1 mm

Adjustable and unique: These industrial shock absorbers from ACE, which can be precisely adjusted both at the front and rear, also contribute towards the success of the MAGNUM range. Equipped with excellent sealing technology, an annealed guide bearing and integrated positive stop, they are robust and durable.

These dampers absorb 50 % more energy than their predecessors but are built even more compactly. The larger range of effective loads also opens up various options in design and assembly. This makes the ML range especially suitable for effective loads of 300 kg to 500,000 kg. Where work is done with changing application data and wherever flexibility is required, they make the best option.

Material Outer body: nitride hardened steel; Piston rod: hard chrome plated steel; Rod end button: hardened steel and corrosion-resistant coating; Return spring: zinc plated or plastic-coated steel; Accessories: steel with black oxide finish or nitride hardened

Damping medium Automatic Transmission Fluid (ATF)

Note

A noise reduction of 3 dB to 7 dB is possible when using the special impact button (PP). For emergency use only applications and for continous use (with additional cooling) it is sometimes possible to exceed the published max. capacity ratings. In this case, please consult ACE.

Safety information

External materials in the surrounding area can attack the seal components and lead to a shorter service life. Please contact ACE for appropriate solution suggestions. Do not paint the shock absorbers due to heat emission.

On request

Special oils, nickel-plated, increased corrosion protection, mounting inside air cylinders or other special options are available on request.
