About the Airtac MIJ Adjustable Cylinder MIJ32X25-20S
Dial in a precise forward end position on the fly with the AirTAC MIJ32X25-20S, a round-body stainless mini cylinder built for double-acting service. An external stop screw lets you shorten the extend stroke by up to 20 mm directly on the machine, covering a usable forward range of 5 to 25 mm without swapping parts. Retract travel remains at the full 25 mm. The riveted stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion and washdown environments.
This Ø32 bore delivers substantial output, pushing with 402.2 N and pulling with 345.6 N at 0.5 MPa. For sizing a light vertical lift, expect to move about 20.5 kg safely with a 2:1 margin. It runs on a 1/8" port with an M10x1.25 male rod thread. Because this is a larger bore, it is a non-ISO-6432 round-body design. The -S suffix means a piston magnet is installed, ready to accept CMSG, DMSG or EMSG sensors for position feedback.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MIJ Adjustable Cylinder MIJ32X25-20S Is Used
Press Fit Dialing
Trim the 20 mm extend stroke to seat delicate bearings precisely, leveraging the 402.2 N push force without over-traveling into the part.
Variable Stop Gate
Adjust the forward stop on the fly to handle mixed carton sizes on a line, using the 345.6 N pull force to retract the gate reliably.
Staged Forming Push
Set intermediate forward positions for folding carton flaps before final sealing, taking up mechanical tolerances across different material thicknesses.
Is the Airtac MIJ Adjustable Cylinder MIJ32X25-20S the Right Cylinder?
When sizing this actuator, note that stepping down to a Ø25 MIJ bore drops the 0.5 MPa push force to 245.3 N, while stepping up to a Ø40 MIJ bore raises it to 628.3 N. The 20 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds during changeovers, letting one SKU cover several intermediate stops. The stop screw sets the forward end position but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve if you must hold a suspended load.
Mounting options include LB foot, FA flange and TC trunnion brackets, plus CA, U, R and CM back covers (the SDB pivot block is not offered on this adjustable variant). Speeds span 30-800 mm/s, and fixed TPU bumper pads absorb the end-of-stroke impact. Add reed or electronic switches via the built-in magnet to confirm your dialed-in position.
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 MIJ32X25-20S FAQ
At 0.5 MPa this Ø32 bore cylinder pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a 1/8" air port and an M10x1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 20 mm on site, giving a usable forward range of 5 to 25 mm, while retract remains at the full 25 mm. The screw only sets the end position and is not a mid-stroke lock. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors.
