Airtac MICJ Adjustable Mini Cylinder MICJ25X75-40S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X75-40S 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 MICJ25X75-40S
Tune the forward stop on site without swapping hardware: the AirTAC MICJ25X75-40S uses an external screw to shorten the extend end position by up to 40 mm, giving a usable forward range of 35-75 mm. Retract remains full stroke. This double-acting round-body mini cylinder pairs that settable stop with an adjustable air cushion at both ends, soaking up high-speed shock so you control both the impact and the final position.
Built with a stainless-steel barrel and Ø10 mm piston rod, it resists mild corrosion and washdown while dropping into standard ISO 6432 mini-cylinder brackets. The 1/8" port feeds a bore that pushes 245.3 N at 0.5 MPa. For practical sizing, expect a safe working load near 147 N, which moves about 12.5 kg vertically with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for position feedback.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-40S Is Used
Adjustable Clamping Press
Dial in the exact 35-75 mm extend reach for clamping aluminum extrusions, relying on the 245.3 N push force and dual air cushions to absorb the high-speed impact.
Variable Stroke Divertor
Shift light cartons on a washdown line using the stainless construction, fine-tuning the forward stop up to 40 mm to handle different box sizes without changing cylinders.
Product Sorting Gate
Use the CMSG sensor to confirm position and the adjustable end-stop to precisely time the stroke when kicking varying product widths off a packaging belt.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-40S the Right Cylinder?
When sizing this 25 mm bore, step down to the 20 mm variant if your load is lighter—it pushes 157 N at 0.5 MPa—or step up to the 32 mm bore (402.2 N at 0.5 MPa) if you need more thrust. Choose this model when you need rapid, repeatable set-position moves; the external stop screw dials in the extend end, while the needle-set air cushions decelerate the piston at high speed. Note that the stop screw and cushion only manage end-of-stroke impact—they do not lock the piston mid-stroke. If you need to hold a load on air loss, install an external rod lock or pilot check valve. For mounting, use LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not offered on this adjustable variant), and rely on the -S magnet for CMSG, DMSG, or EMSG switches.
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 MICJ25X75-40S FAQ
This double-acting cylinder has a 1/8" air port. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, and a theoretical maximum of 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 40 mm on site, while a needle valve adjusts the air cushion at both ends to decelerate the piston at high speed. The cushion and stop screw do not lock the piston mid-stroke; the cylinder drifts on air loss, so use an external rod lock for holding. The -S magnet enables CMSG, DMSG, and EMSG sensors.
