About the Airtac MIJ Adjustable Cylinder MIJ32X400-75S
Dial in a precise forward end position on-site with the AirTAC MIJ32X400-75S, a round-body stainless mini cylinder featuring a 75 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from a 400 mm nominal down to 325 mm, absorbing setup tolerances or covering multiple stop points with one part number. Retract remains a full 400 mm. The Ø32 bore delivers 402.2 N of push force at 0.5 MPa, yielding a computed safe working load of about 241 N or a 20.5 kg vertical lift with a 2:1 margin.
Built with a riveted stainless-steel barrel and Ø12 mm rod, this double-acting unit resists mild corrosion and washdown environments. It uses fixed TPU bumper pads to decelerate the stroke end and operates at 30-800 mm/s. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG position switches. Air connects via a 1/8" port, and the male rod thread is M10x1.25. Note that Ø32 is a non-ISO-6432 size.

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 MIJ32X400-75S Is Used
Diverter Gate Positioning
Sets a precise 325-400 mm extend reach to deflect packages on a conveyor, using the 402.2 N thrust to push varying carton weights without overtravel.
Multi-Stop Machining Feed
Allows a single cylinder to feed raw stock to two distinct machining depths by dialing the external stop nut between cycle setups.
Pallet Changeover Stop
Absorbs mechanical tolerances on pallet staging lines by fine-tuning the forward stop position on the fly, handling loads safely within its 241 N working limit.
Is the Airtac MIJ Adjustable Cylinder MIJ32X400-75S the Right Cylinder?
When sizing this model, the 402.2 N push force at 0.5 MPa handles moderate actuation, but if your application requires less energy, stepping down to the Ø25 bore provides 245.3 N. If you need to move heavier fixtures, the Ø40 bore supplies 628.3 N. The 75 mm adjuster is ideal for fine-tuning the extend endpoint during changeovers without machining new hard stops. For vertical or suspended loads, remember the piston will drift on air loss; the stop screw sets the end position but is not a mid-stroke lock, so fit an external pilot check valve or rod lock if you need to hold the load. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is unavailable on this adjustable variant).
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 MIJ32X400-75S FAQ
This double-acting cylinder uses a 1/8" air port. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 75 mm (usable extend 325-400 mm); retract remains full stroke. The screw is an end-position stop, not a mid-stroke lock. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors.
