Airtac MICJ Adjustable Mini Cylinder MICJ20X80-20S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X80-20S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 80mm 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 MICJ20X80-20S
Trim the forward stop on site without swapping hardware: the AirTAC MICJ20X80-20S uses an external screw to shorten the extend stroke by up to 20 mm, giving a usable 60-80 mm forward range while retract remains full. An adjustable air cushion at both ends soaks up high-speed shock so you set the position and control the impact.
Built as a stainless-steel round-body mini cylinder, the riveted barrel and rod resist mild corrosion and washdown. The Ø20 bore runs on a 1/8" port and delivers 157 N push at 0.5 MPa, yielding a safe working load of roughly 94 N or about an 8 kg vertical lift with a 2:1 margin. Because this SKU carries the -S suffix, a built-in piston magnet is ready for CMSG, DMSG or EMSG switches.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-20S Is Used
Dial-in Clamping
Set the exact 60-80 mm extend reach for clamping aluminum housings; the dual air cushions absorb the impact of rapid 157 N moves.
Divert Stopper
Act as an adjustable height gate on a conveyor; tweak the 20 mm stop range on site to match varying carton sizes without changing brackets.
Light Lift Station
Raise 8 kg product trays vertically using the 0.5 MPa push force, relying on the -S magnet to confirm extend and retract positions.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-20S the Right Cylinder?
Size both ways against the 157 N push at 0.5 MPa: step down to the Ø16 bore (100.5 N push) for lighter grips, or up to the Ø25 bore (245.3 N push) if you need more authority. The Ø20 fits the ISO 6432 mini-cylinder mounting interface, dropping into standard brackets and clevises. Use LB foot, FA flange or TC trunnion mounts, but note the SDB pivot-block is not offered on this adjustable variant.
The external stop screw and needle cushions are ideal for fast, settable-position moves, but the cylinder will not hold a load on air loss—the piston drifts and the cushion only decelerates near stroke end. For a suspended load, add an external rod lock or pilot-operated check valve.
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 MICJ20X80-20S FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical max is 32 kgf at 1.0 MPa. The air port is 1/8".
An external screw shortens the extend stroke by up to 20 mm (retract is unaffected), while needle valves tune the adjustable air cushion at both ends to decelerate high-speed moves. The cushion only slows the piston near the end of travel—it is not a mid-stroke lock or brake, so the cylinder drifts on air loss.
