About the Airtac MIJ Adjustable Cylinder MIJ40X500-75
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-75, a round-body stainless-steel mini cylinder featuring a 75 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 500 mm nominal length down to 425 mm, absorbing setup tolerances without swapping parts. The retract stroke remains full length. Built with a stainless-steel barrel and Ø16 mm piston rod, this riveted construction resists mild corrosion and washdown environments.
It runs at speeds from 30-800 mm/s and relies on fixed TPU bumper pads to decelerate the stroke end. Note this Ø40 size is a non-ISO-6432 round-body unit, and because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG 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 Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 MIJ40X500-75 Is Used
Variable Depth Carton Sealing
Fine-tune the forward stroke down from 500 mm to match different box depths on the fly, using the fixed TPU bumpers to soften the end impact during high-speed packaging changeovers.
Adjustable Pallet Stops
Deploy the 40 mm bore as an adjustable pallet stop gate where the exact forward position needs 25 to 75 mm of tolerance take-up to accommodate varying pallet overhang.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-75 the Right Cylinder?
When sizing this 40 mm bore, moving down to an MIJ32 drops the 0.5 MPa push force to 402.2 N, while stepping up is impossible as this is the largest available MIJ diameter. The 75 mm external stop screw is ideal for changeover jobs where you need one part number to cover several staged feed distances. Just remember the screw only trims the extend end; it does not act as a mid-stroke lock or brake.
This cylinder does not hold its load on air loss, as the piston will drift when valve pressure is centered or lost. To suspend a vertical load safely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit. For mounting, you can utilize LB foot, FA flange, or TC trunnion brackets, along with CA, U, R, or CM back covers, but the SDB pivot-block is not available 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 MIJ40X500-75 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 75 mm (usable range 425-500 mm); retract remains full. The screw sets the end position but is not a mid-stroke lock. The cylinder will drift on air loss, so use a pilot check valve for holding. Also, this non-magnet SKU cannot take sensors.
