About the Airtac MIJ Adjustable Cylinder MIJ40X500-50
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-50, a round-body stainless mini cylinder featuring a 50mm adjustable extend window. An external stop screw lets you shorten the forward stroke from its 500mm nominal length down to 450mm without changing the unit, absorbing setup tolerances or accommodating multiple part stops from one SKU. The retract stroke remains full.
Built with a stainless-steel barrel and rod for mild corrosion and washdown resistance, this double-acting actuator delivers substantial force, pushing 628.3N and pulling 527.8N at 0.5MPa. It uses a 1/4" port and a 16mm rod with an M12x1.25 male thread. Because this is a non-magnet SKU, it cannot accept CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection. Fixed TPU bumper pads decelerate the stroke ends, operating at speeds of 30-800 mm/s.

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 MIJ40X500-50 Is Used
Heavy Fixture Positioning
Dial in the exact 450-500mm extend reach for large machining fixtures, using the stop screw to compensate for tooling tolerances without remounting the cylinder.
Divertor Gate Actuation
Power a heavy-duty divertor gate on a sorting conveyor, fine-tuning the gate extension by up to 50mm to accommodate different package sizes on the fly.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-50 the Right Cylinder?
The 50mm adjustment window is highly useful for changeover jobs, letting one cylinder cover a range of extend positions. Note that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for holding. Mounting options include LB foot, FA flange, and TC trunnion (SDB pivot-block is not available), with back covers CA, U, R, or CM.
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 MIJ40X500-50 FAQ
This 40mm bore cylinder uses a 1/4" port and a 16mm rod with an M12x1.25 thread. It pushes 628.3N and pulls 527.8N at 0.5MPa, pushes 879.6N and pulls 738.9N at 0.7MPa, with a theoretical max of 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 50mm on-site, setting the forward end position (retract remains full). This SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors; you need the -S variant for sensing. The stop screw is not a mid-stroke lock.
