About the Airtac MIJ Adjustable Cylinder MIJ32X80-30S
Dial in your forward end position on site with the AirTAC MIJ32X80-30S, a double-acting round-body mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 80 mm nominal length down to 50 mm without swapping parts, absorbing mechanical tolerances or handling multiple setup jobs under one SKU. Retract travel remains full length, and the stop screw functions only as an end-position setter, not a mid-stroke lock.
Built with a stainless-steel barrel and rod for mild corrosion and washdown resistance, this riveted unit delivers 402.2 N of push force at 0.5 MPa. That translates to a safe working load of roughly 241 N, or a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. The bore uses a 1/8" port and a 12 mm rod, and because this is a -S model, the built-in piston magnet supports CMSG, DMSG and EMSG sensors for position detection. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.

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 MIJ32X80-30S Is Used
Staged Part Ejection
Use the 30 mm extend adjustment to tune the ejection stroke precisely as product sizes change on the line, relying on the 402.2 N push force to clear heavy components reliably.
Tolerance Take-Up Clamping
Absorb mechanical variances in multi-part fixtures by dialing the forward stop in 1 mm increments, applying up to 241 N of safe working clamping force without over-stroking.
Adjustable Diverting Gate
Set the exact extend position needed to route different carton sizes on a sorting conveyor, leveraging the 20.5 kg vertical lift capacity to actuate heavier guide arms.
Is the Airtac MIJ Adjustable Cylinder MIJ32X80-30S the Right Cylinder?
When sizing this 32 mm bore, step down to the MIJ25 (245.3 N push @0.5 MPa) for lighter duties, or move up to the MIJ40 (628.3 N push @0.5 MPa) if your payload exceeds the 241 N safe working load calculated here. The 30 mm external adjuster is ideal for changeover jobs where you need to tune the extend endpoint to slightly different stops without machining new mounts. Choose LB foot, FA flange or TC trunnion mounting, noting that the SDB pivot block is not offered on this adjustable variant.
Remember that a standard pneumatic cylinder does not hold position on air loss; the piston will drift if pressure drops, as the TPU bumper only softens the end stop and does not act as a brake. If your load must remain fixed during a failure, install an external rod lock or pilot-operated check valve. The included -S magnet allows direct mounting of CMSG, DMSG or EMSG switches.
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 MIJ32X80-30S FAQ
This 32 mm bore cylinder uses a 1/8" port and a 12 mm rod. At 0.5 MPa it provides 402.2 N push and 345.6 N pull force. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 30 mm on site, setting the forward end position without affecting the full retract stroke. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG or EMSG sensors. The stainless build offers mild washdown resistance.
