Airtac MICJ Adjustable Mini Cylinder MICJ20X60-30S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X60-30S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 60mm 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 MICJ20X60-30S
Dial in the forward stop on-site without swapping cylinders: the MICJ20X60-30S uses an external screw to shorten the extend stroke by up to 30 mm, yielding a usable 30-60 mm forward range. 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.
The Ø20 mm bore runs on a 1/8" port and an M8x1.25 male rod thread, delivering 157 N of push force at 0.5 MPa. That translates to a safe working load of roughly 94 N, or a vertical lift of about 8 kg with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors, and the stainless barrel and rod resist mild corrosion in washdown settings.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X60-30S Is Used
Light-Part Ejector
Ejects small molded parts at high speed, using the 30 mm extend stop to tune the push distance and the air cushion to absorb impact without banging.
Transfer Diverter
Pushes lightweight cartons on a conveyor; the 8 kg vertical lift capacity handles the transition smoothly while sensors confirm the extend position.
Flap Tucking Arm
Tucks packing flaps on demand where a fixed 60 mm stroke would over-travel, using the adjustable forward stop to prevent crushing the box.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X60-30S the Right Cylinder?
For lighter jobs, the Ø16 bore drops to 100.5 N push @0.5 MPa, while stepping up to the Ø25 bore yields 245.3 N push @0.5 MPa if you need more muscle. Choose this Ø20 model when you need fast, repeatable set-position moves where the adjustable stop and needle-set cushion prevent end-of-stroke banging. Note that the stop screw only sets the end position—it is not a mid-stroke lock, and the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange or TC trunnion (SDB pivot-block is not offered on this adjustable variant).
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 MICJ20X60-30S FAQ
It has a 1/8" port and delivers 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
The external screw shortens the extend stroke by up to 30 mm (retract remains full), while the adjustable air cushion at both ends decelerates the piston near stroke end to reduce shock. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
