About the Airtac MIJ Adjustable Cylinder MIJ32X40-40H
Dial in your forward end position on-site with the AirTAC MIJ32X40-40H, a round-body stainless steel mini cylinder featuring a 40mm adjustable extend stroke. An external stop screw lets you shorten the forward travel by up to 40mm to absorb setup tolerances, meaning one part number can cover several intermediate stop points without swapping hardware. The retract stroke remains full length, and the screw strictly sets the end position rather than acting as a mid-stroke lock.
Built with a stainless-steel barrel and rod for mild washdown resistance, this double-acting unit pushes with 402.2N at 0.5 MPa. The bore is 32mm, the port is 1/8", and this -H variant utilizes Viton seals for elevated temperature environments. Note that because this SKU lacks the -S magnet, it cannot accept position sensors.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 MIJ32X40-40H Is Used
Tooling Changeover
Fine-tune the forward stop during quick tooling changes, using the 40mm adjuster to match new part depths without swapping cylinders.
Heat-Seal Positioning
Set precise sealing jaw depth on packaging equipment; the Viton seals withstand high ambient temperatures near heat sources.
Is the Airtac MIJ Adjustable Cylinder MIJ32X40-40H the Right Cylinder?
The 40mm adjustment window is highly useful for changeover jobs where you need to tune the extended reach without machining new hard stops. Keep in mind that a standard cylinder drifts on air loss; the TPU bumper pads only decelerate the stroke end, so install an external pilot check valve if you must hold a vertical load. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is not offered on adjustable-stroke models).
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 MIJ32X40-40H FAQ
It has a 1/8" port. At 0.5 MPa it pushes 402.2N and pulls 345.6N. At 0.7 MPa it pushes 563N and pulls 483.8N. The theoretical maximum force is 82 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 40mm on-site; retract remains full. It is double-acting with fixed TPU bumpers. It cannot hold position on air loss and this non-S SKU cannot take sensors.
