Airtac MIJ Adjustable Cylinder MIJ20X75-20STC
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X75-20STC is a genuine double acting, adjustable stroke 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 MIJ Adjustable Cylinder MIJ20X75-20STC
Dial in your forward travel precisely with the AirTAC MIJ20X75-20STC, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 20 mm on site, giving a usable forward range of 55 to 75 mm without swapping parts. The retract stroke remains full length. Because the barrel and piston rod are stainless, the unit resists mild corrosion and washdown environments.
At 0.5 MPa, this Ø20 bore generates 157 N of push force and 131.9 N of pull force, yielding a safe working load of about 94 N or a vertical lift capacity near 8 kg with a 2:1 margin. It conforms to the ISO 6432 mounting interface for standard mini brackets and uses a 1/8" port with an M8x1.25 male rod thread. The built-in magnet (-S) supports CMSG, DMSG, or EMSG sensors, while fixed TPU bumper pads absorb end-of-stroke impacts.

Where the Airtac MIJ Adjustable Cylinder MIJ20X75-20STC Is Used
Staged Ejection Diverter
Trim the 75 mm extend stroke by up to 20 mm to push parts of varying sizes onto a secondary belt without repositioning the cylinder mount.
Carton Flap Tucking
Fine-tune the forward end position to tuck flaps on different box heights, using the 157 N push force to cleanly fold light cardboard.
Sensor Probe Placement
Dial in the exact forward stop for delicate testing probes, ensuring the rod touches the target without overtravel on delicate components.
Is the Airtac MIJ Adjustable Cylinder MIJ20X75-20STC the Right Cylinder?
When sizing this actuator, consider the adjacent bores: the smaller Ø16 MIJ provides 100.5 N push at 0.5 MPa, while the larger Ø25 MIJ offers 245.3 N. The Ø20 hits a practical middle ground at 157 N. The 20 mm adjustment window is highly useful for taking up mechanical tolerances or staggering part ejection during setup. You can utilize the TC trunnion mount for pivoting, though the SDB pivot block is not offered on this adjustable variant.
Remember that the external stop screw sets the forward end position but acts purely as a physical stop, not a mid-stroke lock. If your application must hold a load vertically during air loss, the piston will drift. You must integrate an external rod lock or pilot-operated check valve for secure load holding.
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 MIJ20X75-20STC FAQ
This double-acting cylinder uses a 1/8" port. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa, push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm, but the retract stroke remains full length. The -S in the model code indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors.
