Airtac MIJ Adjustable Cylinder MIJ20X80-10S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X80-10S is a genuine double acting, adjustable stroke 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 MIJ Adjustable Cylinder MIJ20X80-10S
Dial in your forward end position on-site with the AirTAC MIJ20X80-10S, a round-body stainless steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 10 mm without swapping parts. Built as a double-acting unit with a Ø20 mm bore and 80 mm nominal stroke, it delivers 157 N of push force at 0.5 MPa, yielding a safe working load of roughly 94 N or a 2:1 margin vertical lift of about 8 kg. The retract stroke remains full length, while fixed TPU bumper pads decelerate the piston at the ends.
This riveted construction cylinder uses a Ø8 mm piston rod, an M8x1.25 male rod thread, and a 1/8" air port. Because the bore falls within the Ø8-Ø25 range, it conforms to the ISO 6432 mounting interface for standard mini brackets and clevises. The included -S piston magnet supports CMSG, DMSG, and EMSG position switches, allowing you to track the adjustable forward end electronically.

Where the Airtac MIJ Adjustable Cylinder MIJ20X80-10S Is Used
Tolerance Take-Up Gauging
Use the 10 mm extend adjustment to compensate for part stacking variations, delivering a consistent 157 N push to seat components without re-engineering the fixture.
Staged Feed Diverter
Fine-tune the forward stop on the fly to push mixed-size cartons accurately onto downstream lanes using the same cylinder setup.
Vertical Lift Stop
Lift approximately 8 kg of stock vertically and tweak the extend end by up to 10 mm to avoid over-traveling into upper tooling.
Is the Airtac MIJ Adjustable Cylinder MIJ20X80-10S the Right Cylinder?
When sizing this unit, step down to the MIJ16 (100.5 N push @0.5 MPa) for lighter loads or up to the MIJ25 (245.3 N push @0.5 MPa) if you need more thrust. The 10 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering several closely spaced stop points with a single part number. Remember that the stop screw sets the forward end position but acts purely as an end stop, not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve if you must hold a suspended load. Mount via LB foot, FA flange, or TC trunnion, noting that the 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 MIJ Adjustable Cylinder MIJ20X80-10S FAQ
This double-acting cylinder uses a 1/8" air port and generates 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 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 10 mm on-site, while the retract stroke remains full length. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors.
