About the Airtac MICJ Adjustable Mini Cylinder MICJ16X125-40S
Dial in the forward stop on site with the AirTAC MICJ16X125-40S, a stainless-steel round-body mini cylinder that shortens the extend stroke by up to 40 mm via an external screw. It pairs this settable end position with an adjustable air cushion at both ends to soak up high-speed shock. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position feedback.
It uses an M5×0.8 port, an M6x1.0 male rod thread, and conforms to the ISO 6432 mounting interface for easy bracket drops. The stainless barrel and rod resist mild washdown corrosion.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 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 MICJ Adjustable Mini Cylinder MICJ16X125-40S Is Used
Micro-Dispense Head
Trims the extend out by 40 mm to hit a precise fluid dispense depth, while the cushion absorbs the 30-800 mm/s approach shock.
Carton Flap Tapper
Stainless build handles mild washdown, while the adjustable forward stop dials the tap distance without swapping hardware.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X125-40S the Right Cylinder?
For lighter moves, the MIJ bumper-only series lacks this air cushion, making the MICJ16 the minimum bore for tuned shock absorption here. Use this Ø16 model when you need fast, settable extend positions between 85 and 125 mm.
The stop screw and cushion only decelerate near the stroke end; they do not lock the piston mid-stroke. Add an external rod lock or pilot check valve if you must hold a vertical load on air loss. Mount via LB, FA, or TC brackets (SDB is not offered), and route air through the M5×0.8 port.
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 MICJ Adjustable Mini Cylinder MICJ16X125-40S FAQ
This double-acting cylinder pushes at 100.5 N and pulls at 86.4 N at 0.5 MPa. At 0.7 MPa, push is 140.7 N and pull is 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. It uses an M5×0.8 air port and a 6 mm piston rod.
An external screw shortens the extend stroke by up to 40 mm on site, giving a usable forward range of 85-125 mm; retract remains full. A needle-set adjustable air cushion at both ends absorbs end-of-stroke shock but does not lock the piston. The -S means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
