The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X75-30S 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.
Dial in a precise forward end position on-site with the AirTAC MIJ20X75-30S, a round-body stainless steel mini cylinder featuring a 30mm adjustable extend window. An external stop screw lets you shorten the forward stroke from its 75mm nominal length down to 45mm without swapping parts, absorbing mechanical tolerances during setup. Because the adjuster trims the extend end only, the retract stroke remains full. The -S suffix equips this unit with a piston magnet for position sensing.
Built with a riveted stainless barrel and rod for mild washdown resistance, this double-acting actuator delivers 157N of push force at 0.5MPa. 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. For a stable vertical lift, expect it to move about 8kg safely with a 2:1 margin, yielding a safe working load near 94N.

| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Trim the extend stroke by up to 30mm on the fly to deflect varying carton sizes off a belt without changing the cylinder mount.
Absorb part-to-part variance during clamping by fine-tuning the forward stop, applying the 157N thrust precisely where needed.
Set distinct forward end positions for different pallet heights, safely lifting around 8kg vertically during automated loading.
When sizing this 20mm bore against neighboring options, step down to the MIJ16 (100.5N push @0.5MPa) for lighter clamping, or up to the MIJ25 (245.3N push @0.5MPa) if you need heavier thrust. The 30mm external stop screw is ideal for changeover jobs where one cylinder must cover several intermediate stops. Mount via LB foot, FA flange, or TC trunnion (SDB pivot block is not offered on this adjustable variant). Pair the built-in magnet with CMSG, DMSG, or EMSG switches for electronic or reed sensing. Remember that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve to hold a suspended load.
Quick checklist
This 20mm bore cylinder uses a 1/8" port. At 0.5MPa it provides 157N push and 131.9N pull. At 0.7MPa it provides 219.8N push and 184.7N pull. The theoretical maximum force is 32kgf at 1.0MPa.
An external stop screw shortens the extend stroke by up to 30mm (usable range 45-75mm); the retract stroke remains full. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. Fixed TPU bumper pads decelerate the stroke ends.
