Airtac MICJ Adjustable Mini Cylinder MICJ25X75-75
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X75-75 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 75mm 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 MICJ25X75-75
Dial in the forward stop on site without swapping cylinders: the MICJ25X75-75 uses an external screw to shorten the extend stroke by up to 75 mm, while a needle-set air cushion at both ends soaks up high-speed shock. This stainless-steel round-body mini cylinder delivers 245.3 N of push force at 0.5 MPa, yielding a safe working load of about 147 N or a 12.5 kg vertical lift with a 2:1 margin.
Built with a stainless barrel and rod for mild washdown resistance, it conforms to the ISO 6432 mounting interface for standard mini brackets. It uses a 1/8" port and an M10x1.25 male rod thread. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors; order the -S variant if you need position detection.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-75 Is Used
Divert Gate Actuation
Sets a precise 40 mm extend stroke to flick a divert gate on a packaging line, using the air cushion to absorb the impact of high-speed routing without slamming.
Light Press Seating
Provides a safe 147 N working load to gently seat a bearing or plug, trimming the forward stop on site to hit the exact depth without re-machining stops.
Carton Flap Folding
Folds cardboard flaps at speed, relying on the stainless construction for dusty environments and the adjustable extend to avoid crushing the box.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-75 the Right Cylinder?
This 25 mm bore hits 245.3 N push at 0.5 MPa. If you need less force, the 20 mm bore offers 157 N; if you need more, step up to the 32 mm bore for 402 N. The 75 mm extend adjuster plus dual air cushions make it ideal for fast, settable-position moves, but the stop screw only sets the end position—it is not a mid-stroke lock. The piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB, FA or TC (SDB is not available here).
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 MICJ25X75-75 FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a 1/8" port.
An external screw shortens the extend stroke by up to 75 mm, and a needle valve adjusts the air cushion at both ends to decelerate the piston near the end of travel. The cushion only decelerates; it is not a brake. This SKU has no magnet, so it cannot take sensors—the -S version is required for CMSG/DMSG/EMSG switches.
