About the Airtac MIJ Adjustable Cylinder MIJ25X20-20S
Dial in a precise forward end position on-site with the AirTAC MIJ25X20-20S, a double-acting round-body mini cylinder featuring a 20 mm adjustable extend stroke. An external stop screw lets you trim the forward travel by up to 20 mm without swapping components, while retract remains full length. Built with a stainless-steel barrel and piston rod, it handles mild corrosion and washdown environments. It uses the ISO 6432 mounting interface for standard mini brackets.
The 1/8" port and M10x1.25 male rod thread ensure solid connections. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly for position detection.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MIJ Adjustable Cylinder MIJ25X20-20S Is Used
Tolerance Take-Up Clamping
Trim the 20 mm extend stroke to absorb part tolerances and deliver a consistent 245.3 N clamping force at 0.5 MPa without repositioning the cylinder body.
Adjustable Transfer Diverter
Fine-tune the forward stop on a conveyor diverter gate on-site, using the 12.5 kg vertical lift capacity to route varying package sizes precisely.
Is the Airtac MIJ Adjustable Cylinder MIJ25X20-20S the Right Cylinder?
The 20 mm external adjuster is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with a single part number. Mount using LB foot, FA flange, or TC trunnion brackets; note that the SDB pivot-block is not available on this adjustable variant.
Remember that the stop screw sets the end position but does not function as a mid-stroke lock. The cylinder will drift on air loss, and the fixed TPU bumper pads only decelerate the stroke end. To hold a load securely, integrate an external rod lock or 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 MIJ25X20-20S FAQ
It uses a 1/8" air port and a Ø10 mm piston rod with an M10x1.25 male thread.
The external stop screw shortens the extend stroke by up to 20 mm on-site, allowing you to set the exact forward position without changing the cylinder; retract remains full. The -S suffix indicates a built-in piston magnet, enabling the use of CMSG, DMSG, or EMSG sensors for position detection.
