Airtac MICJ Adjustable Mini Cylinder MICJ20X75-20S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X75-20S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm 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 MICJ20X75-20S
Dial in the forward stop on-site without swapping cylinders: the MICJ20X75-20S uses an external screw to shorten the extend end position by up to 20 mm, giving a usable forward range of 55-75 mm. This double-acting, round-body stainless-steel mini cylinder pairs that set-position flexibility with an adjustable air cushion at both ends to soak up high-speed shock.
Built with a stainless barrel and piston rod for mild washdown resistance, it conforms to the ISO 6432 mounting interface for Ø20 bores. It delivers 157 N of push force at 0.5 MPa, translating to a safe working load of about 94 N or a vertical lift of roughly 8 kg with a 2:1 margin. The -S suffix means a built-in piston magnet is present, ready for CMSG, DMSG or EMSG position sensing.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-20S Is Used
Light Part Ejection
Ejecting molded plastic parts at speed, using the 20 mm extend trim to hit the exact knockout position while the dual air cushions absorb the end-of-stroke impact.
Carton Flap Folding
Folding packing carton flaps on the fly, where the 157 N push force handles the cardboard resistance and the external screw dials in the fold depth without changing brackets.
Sorter Diverter Arm
Actuating a diverter arm on a conveyor, relying on the built-in magnet for DMSG sensors to confirm home position and the adjustable cushion to prevent bounce at 800 mm/s.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-20S the Right Cylinder?
Size this bore against its neighbors: a smaller Ø16 MICJ yields 100.5 N push at 0.5 MPa, while stepping up to Ø25 provides 245.3 N. Choose the Ø20 when your payload is around that 8 kg vertical lift mark and you need precise end-position tuning. The external stop screw and needle-valve cushions shine in fast set-position moves where you must tune out impact shock.
Remember that the stop screw sets the end position but is not a mid-stroke lock; the cylinder will drift on air loss, so fit an external rod lock or pilot check valve if you must hold a load. Mount via LB foot, FA flange or TC trunnion (the SDB pivot block is not offered on this adjustable variant). Air ports are 1/8".
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 MICJ20X75-20S FAQ
This double-acting cylinder has a 1/8" air port and an M8x1.25 male rod thread. At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (retract remains full), while a needle valve adjusts the air cushion at both ends to decelerate the piston near the ends. The cushion only decelerates and is not a brake; the cylinder drifts on air loss, so use an external rod lock to hold a load. The -S suffix enables CMSG, DMSG and EMSG sensors.
