Airtac MICJ Adjustable Mini Cylinder MICJ20X200-30S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X200-30S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 200mm 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 MICJ20X200-30S
Trim the forward stop by up to 30 mm on site without swapping hardware using the AirTAC MICJ20X200-30S. This double-acting round-body mini cylinder pairs that extend adjustability with a needle-set variable air cushion at both ends, letting you dial in the exact 170 to 200 mm forward position while soaking up high-speed shock. The stainless-steel barrel and rod resist mild corrosion and washdown environments.
Built to the ISO 6432 mounting interface, this Ø20 bore drops into standard mini brackets and clevises. It pushes with 157 N and pulls with 131.9 N 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 1/8" port and included piston magnet enable CMSG, DMSG or EMSG switches for precise end-of-stroke detection.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-30S Is Used
Light Part Ejection
Pushes light molded parts out of a fixture with 157 N of force, using the 30 mm extend trim to hit the exact drop zone without repositioning the cylinder.
Pallet Diverter
Diverts small packages on a line at speed; the dual adjustable air cushions absorb the shock of the 200 mm extend stroke to prevent bounce.
Flap Folding
Folds carton flaps cleanly using the 8 kg vertical lift capacity, dialing in the forward stop to avoid crushing the box.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-30S the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm version drops the 0.5 MPa push force to 100.5 N, while moving up to a 25 mm bore increases it to 245.3 N. Choose this model when you need fast, repeatable set-position moves where the 30 mm extend trim and dual air cushions prevent harsh impacts at the end of travel. The stop screw sets the forward end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for suspended loads.
Mount using LB foot, FA flange or TC trunnion brackets (SDB pivot-block is not available on this adjustable variant). Because this SKU includes the -S magnet, you can mount CMSG, DMSG or EMSG sensors directly for position feedback.
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 MICJ20X200-30S FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa it pushes with 219.8 N and pulls with 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. This 20 mm bore cylinder uses a 1/8" air port.
An external stop screw shortens the extend stroke by up to 30 mm, letting you set the forward end position on site. Needle-set variable air cushions at both ends decelerate the piston near stroke end to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
