Ammortizzatori miniaturizzati ACE regolabili (MA50EUM-B)

Adjustable
Energy capacity 3.5 Nm/Cycle to 100 Nm/Cycle
Stroke 8 mm to 40 mm
The miniature shock absorbers from the MA30 to MA900 series can be adjusted and precisely adapted to your requirements. For example, the MA150 displays the rolling diaphragm technology from the MC150 to MC600 family and offers all of the advantages of this technology, such as use in pressure chambers. Thanks to long strokes (including 40 mm on the MA900) lower reaction forces result, which provide a soft damping characteristic.
All variations of these units are maintenance-free, ready-to-install machine elements and have an integrated positive stop. They provide the best service where application data changes, where the calculation parameters are not clear or where maximum flexibility in the possible usage is required.
The adjustable miniature shock absorbers from ACE can be used to meet precisely the customer‘s application and are therefore found everywhere in mechanical engineering and many other applications.

• Energy capacity: 3.5 Nm/Cycle to 100 Nm/Cycle
• Impact velocity range: 0.15 m/s to 4.5 m/s. Other speeds on request.
• Operating temperature range: 0 °C to 66 °C
• Mounting: in any position
• Positive stop: Integrated
• Adjustment: Hard impact at the start of stroke, adjust the ring towards 9 or PLUS. Hard impact at the end of stroke, adjust the ring towards 0 or MINUS
• Material: Outer body, Accessories: steel corrosion-resistant coating; Piston rod: hardened stainless steel
• Damping medium: oil, temperature stable
• Application field: linear slides, pneumatic cylinders, swivel units, handling modules, machines and plants, finishing and processing centres, automatic machinery, tool machines, locking systems
• Note: If precise end position datum is required consider use of the stop collar type AH. Shock absorber is preset at delivery in a neutral position between hard and soft.
• Safety instructions: 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: Nickel-plated or other special options available to special order. Models without rod end button.

Adjustable
Energy capacity 170 Nm/Cycle to 6,780 Nm/Cycle
Stroke 23.1 mm to 150 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 series. 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 series 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.
These adjustable industrial shock absorbers are used in all areas of mechanical engineering - e.g. in automation, integrated in linear carriages or pivoting units and also for gantries.

• Energy capacity: 170 Nm/Cycle to 6,780 Nm/Cycle
• Impact velocity range: MA: 0.15 m/s to 5 m/s. ML: 0.02 m/s to 0.46 m/s. Other speeds on request.
• Operating temperature range: -12 °C to +66 °C. Other temperatures on request.
• Mounting: In any position
• Positive stop: Integrated
• Adjustment: Hard impact at the start of stroke, adjust the ring towards 9 or PLUS. Hard impact at the end of stroke, adjust the ring towards 0 or MINUS.
• 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)
• Application field: Linear slides, Swivel units, Turntables, Portal systems, Machines and plants, Tool machines, Machining centres, Z-axes, Impact panels
• Note: A noise reduction of 3 to 7 dB is possible when using the special impact button (PP). For emergency use only applications and for continuous use (with additional cooling) it is sometimes possible to exceed the published max. capacity ratings. In this case, please consult ACE.
• Safety instructions: 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.

The calculation and selection of the most suitable damper should be carried out or be approved by ACE.
