Airtac MIJ Adjustable Cylinder MIJ20X75-30STC
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X75-30STC 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 MIJ20X75-30STC
Trimming the forward end by up to 30 mm via an external stop screw, this double-acting mini cylinder lets you dial in a 45 to 75 mm extend position without swapping parts. The Ø20 mm round-body stainless steel barrel and rod shrug off mild washdown environments while conforming to the ISO 6432 mounting interface for standard mini brackets.
Delivering 157 N of push force at 0.5 MPa, it provides a safe working load of roughly 94 N or a 2:1 margin vertical lift of about 8 kg. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG sensors, and the 1/8" port feeds the 30-800 mm/s speed range. Fixed TPU bumper pads decelerate the stroke end.

Where the Airtac MIJ Adjustable Cylinder MIJ20X75-30STC Is Used
Staged Part Ejection
Use the adjustable 45-75 mm extend to push parts of varying widths off a belt without changing the cylinder, utilizing the 157 N push force for reliable transfers.
Carton Flap Folding
Fine-tune the forward stop on-site to fold different carton depths perfectly, leveraging the 94 N safe working load to crease light cardboard cleanly.
Multi-Height Sorting
Dial in the exact extend position to deflect components down specific chutes during changeovers, using the TC trunnion to handle side loads accurately.
Is the Airtac MIJ Adjustable Cylinder MIJ20X75-30STC the Right Cylinder?
When sizing this bore, step down to the MIJ16 (100.5 N push @0.5 MPa) for lighter tasks, or move up to the MIJ25 (245.3 N push @0.5 MPa) if you need more thrust. The 30 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with one SKU. The TC trunnion mount fits standard clevises, though the SDB pivot-block is not offered on this adjustable variant.
Remember that the stop screw sets the extend endpoint but acts as no mid-stroke lock; the piston will drift if air pressure drops. For holding a suspended load vertically, install an external rod lock or pilot-operated check valve. The included magnet enables position sensing, which a non-S SKU cannot accept.
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 MIJ20X75-30STC FAQ
It features a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on-site, while retract remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors; a non-S SKU cannot take a sensor.
