Airtac MICJ Adjustable Mini Cylinder MICJ20X25-20S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X25-20S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 25mm 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 MICJ20X25-20S
Trim the forward stop by up to 20 mm on site with the AirTAC MICJ20X25-20S, a stainless round-body mini cylinder that pairs an adjustable extend stroke with needle-set air cushions at both ends. Driven by a 1/8" port and an 8 mm rod, it delivers 157 N of push force at 0.5 MPa, yielding a safe working load of roughly 94 N or a 2:1 vertical lift capacity of about 8 kg.
Because this is an -S variant, the built-in piston magnet supports CMSG, DMSG, and EMSG switches for exact position detection. The stainless steel barrel and rod shrug off mild washdown corrosion, and the body drops directly into standard ISO 6432 mini-cylinder brackets without relying on non-standard footprints.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X25-20S Is Used
Adjustable Diverter Gate
Dial in the 5 to 25 mm extend stroke to deflect packages on a conveyor, using the dual air cushions to absorb the impact of high-speed routing without slamming.
Light Press Assembly
Apply up to 94 N of safe working force to seat small components, tweaking the forward stop on the fly to accommodate different part heights without changing tooling.
Washdown Sorting Pusher
Leverage the stainless construction and 8 kg vertical lift capacity to push cartons in humid packing zones, confirming each stroke with CMSG or DMSG sensors.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X25-20S the Right Cylinder?
When sizing this 20 mm bore, dropping down to a 16 mm version reduces the 0.5 MPa push force to 100.5 N, while stepping up to a 25 mm bore raises it to 245.3 N. Choose this 20 mm model when you need fast set-position moves where the adjustable forward stop and dual air cushions tame high-speed impact without requiring cylinder swaps.
The external screw trims the extend end position only and is not a mid-stroke lock; the cylinder will drift on air loss, so add an external rod lock or pilot check valve for suspended loads. Mount it via LB foot, FA flange, or TC trunnion (the SDB pivot block is excluded here), and rely on the -S magnet for electronic or reed sensor 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 MICJ20X25-20S FAQ
This 20 mm bore cylinder uses 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 stop screw shortens the extend stroke by up to 20 mm (usable range 5-25 mm), while needle valves adjust the air cushions at both ends to decelerate the piston near stroke end. The -S indicates a built-in magnet for CMSG, DMSG, or EMSG position switches.
