About the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-50STC
Dial in the forward stop on-site without swapping cylinders: the MICJ40X60-50STC uses an external screw to shorten the extend stroke by up to 50 mm, giving a usable 10-60 mm forward range, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. Built as a double-acting, round-body stainless-steel mini cylinder, it pairs a 1/4" port with a 16 mm rod and M12x1.25 male thread.
The 40 mm bore generates 628.3 N of push force at 0.5 MPa, translating to a safe working load of about 377 N or a 32 kg vertical lift with a 2:1 margin. The stainless barrel and rod resist mild corrosion and washdown, and the built-in magnet (-S) supports CMSG, DMSG and EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-50STC Is Used
Pallet Diverter
Pushes 30 kg pallets onto a side lane using the 628.3 N thrust, relying on the 50 mm extend adjustment to hit the exact divert position without retooling.
Carton Flap Folder
Folds heavy corrugated flaps at high speed; the adjustable air cushion absorbs the shock before the end of the stroke, protecting the 16 mm rod and the packaging.
Vertical Lift Gate
Raises a 32 kg access gate using a 2:1 safety margin on the 0.5 MPa push force, using the TC trunnion to pivot smoothly while the magnet enables position sensing.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-50STC the Right Cylinder?
For lighter loads, the Ø32 bore provides 402.2 N push at 0.5 MPa; if you need more power, there is no larger MICJ bore, so you would step to a different heavy-duty series. Choose this Ø40 model when you need fast, settable-position moves up to 800 mm/s where the adjustable cushion can tame the impact. The TC trunnion mount fits this body, but the SDB pivot-block is not available on this adjustable variant.
Remember that the stop screw sets the end position but is not a mid-stroke lock. A plain cylinder does not hold its load on air loss or when the valve is centered, as the piston drifts and the cushion only decelerates near the stroke end. For a held load, install an external rod lock or a pilot-operated check valve.
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 MICJ40X60-50STC FAQ
This 40 mm bore cylinder has a 1/4" port and generates 628.3 N push / 527.8 N pull at 0.5 MPa, and 879.6 N push / 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 50 mm (usable 10-60 mm), while the needle-set air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The cushion is not a brake or mid-stroke lock, and the piston will drift on air loss. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
