Airtac MICJ Adjustable Mini Cylinder MICJ20X160-30S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X160-30S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 160mm 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 MICJ20X160-30S
Trim the forward stop by up to 30 mm on site without swapping hardware using this stainless steel round-body mini cylinder. The MICJ20X160-30S delivers a 157 N push force at 0.5 MPa and features a needle-set air cushion at both ends to absorb high-speed impact. Because the barrel and rod are stainless, the unit resists mild corrosion and washdown environments.
The external screw adjusts the extend end position only (usable forward travel 130-160 mm), while the retract stroke remains full. It uses the ISO 6432 mounting interface for easy bracket drops, and the -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG sensors. The 1/8" port and M8x1.25 male rod thread keep airflow and mounting standard. Based on the 0.5 MPa push rating, expect a safe working load around 94 N, or a vertical lift of about 8 kg with a 2:1 margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X160-30S Is Used
Light Part Ejection
Dial in a precise 145 mm ejection point with the 30 mm stop screw while the dual air cushions absorb the impact of fast 157 N push strokes.
Diverting Mechanism
Use the built-in magnet with DMSG sensors to confirm arm position when diverting small packages, relying on the 8 kg vertical lift margin.
Carton Forming Stop
Adjust the forward end position on the fly to handle slight carton height variations, letting the needle cushion soak up the high-speed stop.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X160-30S the Right Cylinder?
If you need less push, the smaller Ø16 bore yields 100.5 N at 0.5 MPa but lacks the air cushion feature; if you need more, stepping up to the Ø25 bore provides 245.3 N. This Ø20 model shines when you need fast, repeatable set-position moves, as the 30 mm extend adjuster lets you dial in the exact forward stop while the dual cushions decelerate the load. It will not hold a load on air loss—the piston drifts—so add an external rod lock or pilot check valve for suspended loads. Mount via LB, FA, or TC (SDB is not offered on this adjustable variant), and use CMSG/DMSG/EMSG switches since the -S magnet is present.
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 MICJ20X160-30S FAQ
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 max force is 32 kgf at 1.0 MPa. It uses a 1/8" air port.
An external screw shortens the extend stroke by up to 30 mm (retract is full). Needle valves adjust the air cushions at both ends to decelerate high-speed moves. The cushion only decelerates and is not a brake; the piston drifts on air loss, so use an external rod lock for holding.
