Airtac MIJ Adjustable Cylinder MIJ20X30-20TC
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X30-20TC is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 30mm 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 MIJ20X30-20TC
Trim the forward end position by up to 20 mm on site with the AirTAC MIJ20X30-20TC, a double-acting round-body mini cylinder built around a stainless-steel barrel and rod for mild washdown resistance. Because the external stop screw shortens only the extend stroke, you can dial in a 10 to 30 mm forward travel without swapping parts.
At 0.5 MPa this Ø20 bore delivers 157 N of push force and 131.9 N of pull, yielding a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin. It conforms to the ISO 6432 mounting interface, uses a 1/8" port, and relies on fixed TPU bumper pads to decelerate the stroke end.

Where the Airtac MIJ Adjustable Cylinder MIJ20X30-20TC Is Used
Gauge Positioning
Dial in the exact 10 to 30 mm forward travel to push a measurement gauge into contact, absorbing fixture tolerances with 157 N of thrust at 0.5 MPa.
Staged Part Feeding
Use the adjustable extend stop to meter parts onto a belt without re-specifying the cylinder when product heights change, relying on the TC trunnion for stable pivoting.
Light Press Fit
Apply a safe working load of about 94 N to seat small pins or covers, tweaking the forward end position on-site to prevent over-travel.
Is the Airtac MIJ Adjustable Cylinder MIJ20X30-20TC the Right Cylinder?
When sizing this unit against the range, stepping down to a Ø16 bore drops the 0.5 MPa push force to 100.5 N, while moving up to a Ø25 bore raises it to 245.3 N. The 20 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering multiple stop points with one SKU. This non-magnet SKU cannot host CMSG, DMSG, or EMSG sensors, so add the -S variant if you need position detection. The included TC trunnion mount fits standard ISO 6432 brackets, though the SDB pivot block is not offered on this adjustable-stroke type. Remember that the stop screw sets the end position but does not lock the rod mid-stroke; for holding a load on air loss, install an external pilot check valve or rod lock.
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 MIJ20X30-20TC FAQ
This double-acting cylinder pushes with 157 N and pulls with 131.9 N at 0.5 MPa. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N, with a theoretical max of 32 kgf at 1.0 MPa. The air port is 1/8".
An external stop screw shortens the extend stroke by up to 20 mm, letting you set a 10 to 30 mm forward end position while retract remains full. The screw is not a mid-stroke lock, and the fixed TPU bumpers only decelerate the end of travel; the piston will drift on air loss.
