Airtac MIJ Adjustable Cylinder MIJ8X60-40S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ8X60-40S is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø8mm bore and 60mm 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 MIJ8X60-40S
Dial in a precise forward end position on the spot with this stainless-steel round-body mini cylinder, which uses an external stop screw to shorten the extend stroke by up to 40 mm. The M5x0.8 pneumatic port feeds a 4 mm piston rod to deliver 25.1 N of push force at 0.5 MPa, making it ideal for light-duty routing. Because the rod and barrel are stainless, the riveted construction resists mild corrosion and washdown environments.
This double-acting actuator conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG position sensing. With a practical safe working load of roughly 15 N (about 60 percent of the 0.5 MPa push figure), it provides reliable motion for compact assemblies.

Where the Airtac MIJ Adjustable Cylinder MIJ8X60-40S Is Used
Micro-Clamp Actuation
Provides 25.1 N of push force to secure delicate electronic components, with the 40 mm extend adjustment allowing operators to dial in the exact clamp depth without changing fixtures.
Small-Part Diverter
Sorts lightweight plastic parts on a conveyor using a 1.3 kg vertical lift capacity, fine-tuning the reject stroke on-site to accommodate varying product widths.
Staged Feed Stops
Acts as an adjustable physical stop for a staged feeding mechanism, retracting fully while letting the external screw set precise forward material positioning.
Is the Airtac MIJ Adjustable Cylinder MIJ8X60-40S the Right Cylinder?
For lighter tasks, the MIJ8 is the smallest available bore in this series; stepping up to an MIJ10 increases the 0.5 MPa push force to 39.3 N. The 40 mm adjustment window is highly useful for tolerance take-up during setup, allowing one part number to cover several intermediate stops without swapping hardware. The external screw trims the extend end only, as retract remains a full stroke.
Note 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 for held loads. Mounting options include LB foot, FA flange and TC trunnion (the SDB pivot-block is not available on this adjustable variant). Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.
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 MIJ8X60-40S FAQ
This cylinder uses an M5x0.8 port and a 4 mm rod. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, 35.2 N push and 26.4 N pull at 0.7 MPa, with a theoretical maximum of 5.1 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 40 mm on-site without altering the full retract stroke. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors; a non-S SKU cannot take a sensor.
