Airtac MICJ Adjustable Mini Cylinder MICJ20X20-20S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X20-20S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 20mm 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 MICJ20X20-20S
Trim the forward stop by up to 20 mm on-site without swapping hardware using the AirTAC MICJ20X20-20S. This double-acting, round-body stainless-steel mini cylinder pairs that external extend adjuster with a variable air cushion at both ends, letting you dial in the exact set position and soak up high-speed shock simultaneously. The stainless barrel and piston rod resist mild corrosion and washdown environments. Because this is an -S SKU, it includes a built-in piston magnet for CMSG, DMSG, or EMSG position switches. It uses the ISO 6432 mounting interface and features a 1/8" port.
At 0.5 MPa, the Ø20 bore generates 157 N of push force and 131.9 N of pull force. This translates to a safe working load of about 94 N, or roughly an 8 kg vertical lift with a 2:1 safety margin. The extend adjustment screw sets the end position but does not function as a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X20-20S Is Used
Light Part Ejection
Pushes small plastic or aluminum parts out of a machining fixture with a safe 94 N working load, using the 20 mm extend adjustment to hit the exact drop point.
Package Diverting
Sorts light cartons on a conveyor at high speed; the dual adjustable air cushions absorb the shock at stroke ends to prevent bounce.
Sensor-Confirmed Clamping
Holds a delicate component in place for a secondary operation, using the built-in magnet with a DMSG switch to verify the clamp position before the tool descends.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X20-20S the Right Cylinder?
If you need less force, the smaller Ø16 bore yields 100.5 N of push at 0.5 MPa but lacks the dual cushion feature, making this Ø20 model the better choice for high-speed impacts. If your application exceeds the 157 N push force, step up to the Ø25 bore, which provides 245.3 N. This adjustable-stroke variant accepts LB foot, FA flange, and TC trunnion mounts, but the SDB pivot-block is not available. The -S magnet enables CMSG, DMSG, and EMSG sensors for precise end-of-stroke confirmation.
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 MICJ20X20-20S FAQ
This Ø20 mm cylinder features a 1/8" port and an M8x1.25 male rod thread. It delivers 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 stop screw shortens the extend stroke by up to 20 mm on-site, while the retract stroke remains full. A needle-set variable air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The cushion only decelerates and does not lock the load.
