Airtac MICJ Adjustable Mini Cylinder MICJ20X50-10S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X50-10S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 50mm 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 MICJ20X50-10S
Dial in a precise forward stop on-site with the AirTAC MICJ20X50-10S, a double-acting stainless-steel mini cylinder featuring a 10mm adjustable extend stroke. An external stop screw lets you shorten the extend end position from 40 to 50mm without swapping hardware, while a needle-set adjustable air cushion at both ends absorbs high-speed impact. The Ø20mm round-body design uses the standard ISO 6432 mounting interface for easy bracket interchange.
Built with a stainless barrel and rod for mild washdown resistance, this unit pushes 157N and pulls 131.9N at 0.5 MPa. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches. It yields a safe working load of roughly 94N, meaning it can vertically lift about 8kg with a 2:1 safety margin. Air flows through a 1/8" port, and the M8x1.25 male rod thread handles the linkage.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X50-10S Is Used
Sorting Diverter
Pushes lightweight packages on a belt line; the 10mm extend stop tunes the push distance on the fly while the air cushion silences the high-speed impact.
Clamp Press
Holds an 8kg workpiece fixture against a machining bed. The 157N push force secures the part, and the needle cushion prevents bounce.
Flap Folder
Folds carton flaps at speed. The external screw dials the exact 45mm forward reach to match box dimensions without reprogramming the motion controller.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X50-10S the Right Cylinder?
When sizing this 20mm bore, stepping down to the 16mm version drops the 0.5 MPa push force to 100.5N, whereas moving up to the 25mm bore raises it to 245.3N. Choose this model when you need rapid set-position moves where the adjustable 10mm extend stop and dual-end cushions prevent end-of-stroke banging. The stop screw sets the forward endpoint but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve for held loads.
Mounting options include LB foot, FA flange, and TC trunnion, plus CA, U, R, or CM back covers (SDB pivot-block is unavailable on this adjustable variant). Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for precise end-position 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 MICJ20X50-10S FAQ
It delivers 157N push and 131.9N pull at 0.5 MPa, and 219.8N push / 184.7N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
An external screw shortens the extend stroke by up to 10mm (usable range 40-50mm); retract remains full. Needle valves adjust the air cushion at both ends to decelerate the piston near stroke ends. It does not hold position on air loss, and the -S magnet enables CMSG/DMSG/EMSG sensors.
