About the Airtac MIJ Adjustable Cylinder MIJ40X500-40
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-40, a round-body stainless mini cylinder featuring a 40 mm external stop-screw adjustment window. Rather than swapping components to hit a 460-500 mm extend length, you simply turn the external stop nut to trim the forward stroke while retract remains full. Built with a stainless-steel barrel and Ø16 rod, it handles mild corrosion and washdown environments.
Fixed TPU bumper pads decelerate the piston at the stroke ends, operating at speeds of 30-800 mm/s across a -20 to +70 C 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 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 MIJ40X500-40 Is Used
Heavy Diverter Gate
Shifts loaded pallet routing gates on a conveyor line, using the 40 mm stroke adjustment to fine-tune the gate open angle for varying box widths without repositioning the cylinder.
Large Component Seating
Presses bearings or pins into heavy housings on an assembly line, dialing in the exact 460-500 mm extend position to account for material thickness variations on the fly.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-40 the Right Cylinder?
The 40 mm adjustment window is highly useful for taking up mechanical tolerances or accommodating multiple part stops during changeovers without machining new mounts.
Remember that the stop screw sets the end position but acts purely as an end stop, not a mid-stroke lock. If your application must hold a load vertically during air loss, add an external rod lock or pilot check valve. Mount using LB foot, FA flange, or TC trunnion brackets (SDB is not offered here). Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.
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 MIJ40X500-40 FAQ
At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 40 mm on-site, allowing you to set a precise forward end position between 460 and 500 mm. The retract stroke remains full length. This screw is not a mid-stroke lock or brake, so the piston will drift if air pressure is lost.
