Airtac MICJ Adjustable Mini Cylinder MICJ25X25-30S

The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X25-30S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 25mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MICJ Adjustable Mini Cylinder MICJ25X25-30S

Trim the forward stop by up to 30 mm on site without swapping hardware using the AirTAC MICJ25X25-30S. This double-acting, round-body stainless steel mini cylinder pairs that external extend adjuster with a needle-set air cushion at both ends to soak up high-speed shock. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for exact position detection.

Delivering 245.3 N of push force at 0.5 MPa, it yields a safe working load of roughly 147 N, or about 12.5 kg of vertical lift with a 2:1 margin. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Because it falls within the Ø16 to Ø25 range, it conforms to the ISO 6432 mounting interface for standard mini brackets, and the stainless barrel and rod resist mild corrosion in washdown settings.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X25-30S Is Used

tune

Adjustable Diverter Gate

Fine-tune the 25 mm extend stroke by up to 30 mm to position a routing flap exactly, using the 245.3 N push force to shift packages reliably.

conveyor_belt

High-Speed Product Stop

Deploy the needle air cushions to decelerate the impact of rapid 800 mm/s actuation, halting light cartons on a belt without bounce.

precision_manufacturing

Washdown Clamp Station

Leverage the stainless steel construction and 12.5 kg vertical lift capacity to hold metal parts firmly in mildly corrosive machining environments.

Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X25-30S the Right Cylinder?

If you need less force, the Ø20 bore provides 157 N of push at 0.5 MPa; if your application demands more, stepping up to the Ø32 bore yields 402 N. The Ø25 hits a strong middle ground for moderate loads. The 30 mm extend adjustment window is highly useful when you need to dial in a precise forward position on the fly, while the dual air cushions manage the impact of fast 30-800 mm/s moves.

Remember that the stop screw sets the end position but acts as no mid-stroke lock, and the cylinder will drift on air loss—use an external rod lock or pilot check valve for held loads. For mounting, choose LB foot, FA flange or TC trunnion (SDB pivot-block is not offered on this adjustable variant), and leverage the -S magnet for electronic or reed sensors.

Quick checklist

  • ✓ Required force at your working pressure
  • ✓ Stroke and mounting space
  • ✓ Port/thread type (PT / G)
  • ✓ Magnet (-S) for sensors?
  • ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)

Installation & Maintenance Notes

  • check Use clean air filtered to 40µm or finer.
  • check Keep within 0.15 – 1.0 MPa operating pressure.
  • check Avoid side load on the piston rod.
  • check Do not dismantle the riveted front/back covers.
  • check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
  • check Installation by qualified personnel per AirTAC docs.

Airtac MICJ Adjustable Mini Cylinder MICJ25X25-30S FAQ

This double-acting cylinder pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa, and it uses a 1/8" air port.

An external screw shortens the extend end position by up to 30 mm so you can set the forward stop on site, while retract remains full. An adjustable air cushion at both ends decelerates the piston near stroke ends to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
