Airtac MICJ Adjustable Mini Cylinder MICJ20X250-100S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X250-100S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 250mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments.

About the Airtac MICJ Adjustable Mini Cylinder MICJ20X250-100S
Trim the forward stop by up to 100 mm on site without swapping hardware using this stainless steel round-body mini cylinder. The external screw sets the extend end position from 150 to 250 mm, while the needle-set air cushions at both ends soak up high-speed shock. It is a double-acting unit with a built-in magnet for position sensing.
The Ø20 mm bore runs on a 1/8" port and delivers 157 N of push force at 0.5 MPa. That translates to a safe working load of roughly 94 N, or about 8 kg of vertical lift with a 2:1 safety margin. The stainless barrel and rod resist mild washdown corrosion, and the body drops into standard ISO 6432 mini-cylinder brackets.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X250-100S Is Used
Variable Stroke Clamping
Dial in the 100 mm extend trim to clamp parts of different heights on a single fixture, using the 157 N push force to secure components during machining.
High-Speed Diverting
Rapidly extend and retract across the 250 mm stroke to sort items on a line, relying on the dual air cushions to absorb impact at fast cycling speeds.
Adjustable Push-off
Set the exact forward position to push varying box sizes off a packaging station, lifting or shifting loads up to 8 kg safely with the 2:1 margin.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X250-100S the Right Cylinder?
At 0.5 MPa this 20 mm bore gives 157 N push and 131.9 N pull. If you need less force, the smaller Ø16 bore in the MICJ line provides 100.5 N push; if your load is heavier, step up to the Ø25 bore for 245.3 N push. The adjustable stop plus dual cushions shine when you need fast, repeatable set-position moves without end-of-stroke slamming.
The stop screw sets the extend endpoint but is not a mid-stroke lock, and the piston will drift if air pressure drops. Use an external rod lock or pilot check valve for held loads. For mounting, choose LB foot, FA flange, or TC trunnion (SDB is not offered on this adjustable variant). The -S magnet enables CMSG, DMSG, and EMSG 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 MICJ20X250-100S FAQ
This 20 mm bore cylinder has a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 100 mm on site, giving a usable forward range of 150 to 250 mm; retract remains full. Needle valves adjust the air cushions at both ends to decelerate the piston before impact. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG sensors.
