About the Airtac MIJ Adjustable Cylinder MIJ10X125-40S
Dial in a precise forward end position on-site with the AirTAC MIJ10X125-40S, a round-body stainless steel mini cylinder. An external stop screw lets you shorten the extend stroke by up to 40 mm, giving a usable forward range of 85 to 125 mm without changing the part number. Retract remains at the full 125 mm. Built with a riveted stainless barrel and rod, it resists mild corrosion and handles washdown environments.
Driven by filtered air at 0.15 to 1.0 MPa, this double-acting Ø10 mm bore generates 39.3 N of push force at 0.5 MPa. That translates to a safe working load of about 24 N, or vertically lifting roughly 2 kg with a 2:1 safety margin. It features an M5x0.8 port, a Ø4 mm rod, and conforms to ISO 6432 mounting dimensions. The included -S magnet enables CMSG, DMSG, or EMSG sensors for position detection.

Where the Airtac MIJ Adjustable Cylinder MIJ10X125-40S Is Used
Light-Actuation Clamps
Sets a precise forward clamp position on delicate subassemblies, using the 40 mm adjuster to dial in the exact 24 N safe working load without over-traveling.
Changeover Feed Stops
Handles product family changeovers on a single line by shifting the extend stop between 85 and 125 mm, accommodating different part widths instantly.
Lab Dispense Positioning
Provides repeatable forward positioning for low-force fluid dispensing heads, relying on the stainless build for mild chemical resistance and the -S magnet for timing.
Is the Airtac MIJ Adjustable Cylinder MIJ10X125-40S the Right Cylinder?
Choose this Ø10 bore when you need 39.3 N of push at 0.5 MPa; step up to the Ø12 if you require 56.5 N, or down to the Ø8 for lighter 25.1 N tasks. The 40 mm adjustment window is perfect for taking up mechanical tolerances during setup or covering multiple stop positions in changeover jobs. Remember that the stop screw only trims the extend end and does not lock the piston mid-stroke. The cylinder drifts on air loss, so fit an external rod lock or pilot check valve if you need to hold a load vertically.
This SKU includes the -S piston magnet for position sensing. Mounting options include LB foot, FA flange, and TC trunnion brackets, plus CA, U, R, or CM back covers. Note that the SDB pivot block is not available on this adjustable-stroke 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 MIJ10X125-40S FAQ
At 0.5 MPa it provides 39.3 N push and 33 N pull. At 0.7 MPa it provides 55 N push and 46.1 N pull. The theoretical maximum force is 8 kgf at 1.0 MPa. The air port is M5x0.8.
An external screw shortens the extend stroke by up to 40 mm on-site, but retract remains the full 125 mm. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors. Fixed TPU bumper pads decelerate the stroke ends.
