Airtac MIJ Adjustable Cylinder MIJ8X40-10STC
The AirTAC Airtac MIJ Adjustable Cylinder MIJ8X40-10STC is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø8mm bore and 40mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIJ Adjustable Cylinder MIJ8X40-10STC
Dial in a precise forward end position on-site with the AirTAC MIJ8X40-10STC, a stainless-steel round-body mini cylinder featuring a 10 mm external stop screw that shortens the extend stroke from its 40 mm nominal length. The double-acting mechanism delivers 25.1 N of push force at 0.5 MPa, yielding a safe working load of roughly 15 N or a 1.3 kg vertical lift with a 2:1 margin.
Built to ISO 6432 mounting interface dimensions, this Ø8 bore unit drops into standard mini brackets and utilizes an M5x0.8 air port with an M4x0.7 male rod thread. The stainless barrel and rod resist mild corrosion, and the -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG sensors.

Where the Airtac MIJ Adjustable Cylinder MIJ8X40-10STC Is Used
Micro-Clamp Actuation
Provides a 15 N safe working load to secure delicate electronic components, using the 10 mm stroke adjuster to dial in the exact clamping depth without crushing parts.
Small Part Diverter
Pushes lightweight plastic caps on a conveyor with 25.1 N of force, fine-tuning the extend stop to accommodate different product widths on the same line.
Staged Feed Stops
Acts as an adjustable physical stop for thin metal strips entering a press, retracting fully while allowing 0 to 10 mm of forward position trimming for setup flexibility.
Is the Airtac MIJ Adjustable Cylinder MIJ8X40-10STC the Right Cylinder?
For lighter duties, the MIJ series lacks a smaller bore than Ø8, making this the starting point for miniature tasks; stepping up to a Ø10 bore increases the 0.5 MPa push force to 39.3 N when this 25.1 N unit is insufficient. The 10 mm adjuster is ideal for taking up mechanical tolerances during setup, letting one part number cover several slightly different forward stops without changing the cylinder.
This model includes a TC trunnion mount, though the SDB pivot-block is not offered on this adjustable variant. Remember that the stop screw sets the end position but does not function as a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve if you need to hold a load vertically.
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 MIJ8X40-10STC FAQ
This double-acting cylinder uses an M5x0.8 air port and generates 25.1 N push / 18.8 N pull at 0.5 MPa, and 35.2 N push / 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 10 mm on-site, but retract remains full and the screw is not a mid-stroke lock. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors.
