About the Airtac MIJ Adjustable Cylinder MIJ40X160-75S
Dial in your forward end position on the fly with the AirTAC MIJ40X160-75S, 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 160 mm down to 85 mm directly on the machine, covering multiple stop distances with a single part number. Retract remains at the full 160 mm. Built with a stainless barrel and rod, it handles mild corrosion and washdown environments better than standard units.
Because this is the -S variant, a built-in piston magnet enables position sensing with CMSG, DMSG, or EMSG switches. Deceleration is handled by fixed TPU bumper pads, as this model does not use adjustable air cushions.

| Stroke | 160 mm |
| Acting type | Double acting, double rod, adjustable stroke |
| Port size | 1/4" |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 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 MIJ40X160-75S Is Used
Multi-Stop Clamping Fixture
Set precise forward clamping positions for different machined parts, relying on the 32 kg vertical lift capacity to hold components securely during secondary operations.
Tiered Carton Pusher
Stage products onto lower and upper conveyor tiers by dialing the external screw, using the fixed TPU bumpers to cushion the heavy 40 mm bore impacts at each stop.
Is the Airtac MIJ Adjustable Cylinder MIJ40X160-75S the Right Cylinder?
When sizing this 40 mm bore, check both ends of the range. The 75 mm external adjuster is highly useful for taking up mechanical tolerances during setup or accommodating multiple part lengths in a changeover fixture without physically swapping cylinders. Mounting options include LB foot, FA flange, and TC trunnion blocks, but note that the SDB pivot block is not available on this adjustable-stroke variant.
Keep in mind that the stop screw only sets the forward end position—it is not a mid-stroke lock. The cylinder will drift if air pressure is lost or the valve is centered, so you must use an external rod lock or pilot-operated check valve if the load needs to be held securely in place.
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 MIJ40X160-75S FAQ
This 40 mm bore cylinder uses a 1/4" port and a 16 mm rod. 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 extend 85-160 mm), but 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 magnet for CMSG, DMSG, or EMSG sensors.
