Airtac MICJ Adjustable Mini Cylinder MICJ20X75-75
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X75-75 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 75mm 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 MICJ20X75-75
Trim the forward stop by up to 75 mm on site without swapping cylinders, and let the needle-set air cushions soak up high-speed shock at both ends. The AirTAC MICJ20X75-75 is a double-acting, round-body stainless-steel mini cylinder that merges an adjustable extend stroke with variable impact control.
Built to the ISO 6432 mounting interface for Ø20 bores, it drops into standard mini brackets and clevises. The stainless barrel and rod resist mild corrosion and washdown. Generating 157 N of push force at 0.5 MPa, it handles a safe working load of roughly 94 N, or lifts about 8 kg vertically with a 2:1 margin. This SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors. Pneumatic supply connects via a 1/8" port.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-75 Is Used
Adjustable Sorting Diverter
Dial in the 75 mm extend stop to route small packages on a conveyor, using the dual air cushions to absorb shock during rapid 157 N switching cycles.
Light Part Clamping
Securely hold an 8 kg workpiece against a machining stop, fine-tuning the forward position on-site without swapping hardware.
Lab Dispense Head
Lower a dispensing nozzle precisely in washdown environments; the stainless build resists mild corrosion while the needle cushion decelerates the fast approach.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-75 the Right Cylinder?
When sizing this 20 mm bore, step down to the 16 mm version (100.5 N push @0.5 MPa) for lighter tasks, or up to the 25 mm bore (245.3 N push @0.5 MPa) if your load exceeds the 94 N safe working threshold. The 75 mm extend adjuster and dual air cushions excel in fast, settable-position moves where you must dial in the exact forward stop and control end-of-stroke impact.
The external screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve to hold a suspended load. Choose LB foot, FA flange, or TC trunnion mounts, as the SDB pivot-block is unavailable here. Because this is a non-magnet SKU, position sensing is not supported.
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 MICJ20X75-75 FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. Air supply connects via a 1/8" port.
An external screw shortens the extend stroke by up to 75 mm, while needle-set air cushions at both ends decelerate the piston near stroke end. The cylinder does not hold position on air loss, so use an external rod lock for suspended loads. This non-S SKU lacks a magnet, meaning CMSG, DMSG, or EMSG sensors cannot be fitted.
