Airtac MIJ Adjustable Cylinder MIJ20X75-50S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X75-50S 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 MIJ20X75-50S
Dial in your forward end position on the fly with the AirTAC MIJ20X75-50S, a round-body stainless steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 50 mm. You get a usable forward range of 25-75 mm without changing the actuator, while retract remains at the full 75 mm. This double-acting unit pushes with 157 N and pulls with 131.9 N at 0.5 MPa, yielding a safe working load of about 94 N or a 2:1 vertical lift capacity near 8 kg.
The stainless barrel and piston rod resist mild corrosion and washdown environments. Because this SKU carries the -S suffix, it includes a piston magnet for CMSG, DMSG or EMSG sensors. It conforms to the ISO 6432 mounting interface for easy bracket drops, runs at 30-800 mm/s, and uses a 1/8" port with an M8x1.25 male rod thread. Fixed TPU bumper pads decelerate the stroke ends.

Where the Airtac MIJ Adjustable Cylinder MIJ20X75-50S Is Used
Changeover Diverter
Fine-tune the 50 mm extend stop to shift a guide rail for different product widths on a packaging line without swapping actuators.
Tiered Carton Staging
Use the adjustable forward end to push 8 kg cartons to varying stop points, leveraging the 157 N push force for reliable feeding.
Tolerance Take-Up Press
Dial in the exact 25-75 mm forward position to press lightweight components, absorbing part tolerances with the fixed TPU bumpers.
Is the Airtac MIJ Adjustable Cylinder MIJ20X75-50S the Right Cylinder?
When sizing this 20 mm bore, step down to an MIJ16 (100.5 N push @0.5 MPa) for lighter tasks, or step up to an MIJ25 (245.3 N push @0.5 MPa) if you need more thrust. The 50 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds across changeover jobs. You can mount via LB foot, FA flange or TC trunnion, but note the SDB pivot block is not offered on this adjustable variant.
Remember the stop screw sets the forward end position but acts as no mid-stroke lock. If air pressure drops, the piston drifts and the load moves. To hold a vertical load safely, pair this cylinder with an external rod lock or a pilot-operated check valve.
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 MIJ20X75-50S FAQ
This 20 mm bore 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 the 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 50 mm, giving a usable forward range of 25-75 mm, while retract stays at the full 75 mm. The -S suffix means a piston magnet is built in for CMSG, DMSG or EMSG sensors.
