About the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-50S
Trim the forward stop by up to 50 mm on site without swapping hardware using this AirTAC adjustable-stroke mini cylinder. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for exact position detection, while the stainless steel round barrel and rod shrug off mild washdown corrosion.
Delivering 157 N of push force at 0.5 MPa, this double-acting ISO 6432 unit handles a safe working load of roughly 94 N, or about 8 kg of vertical lift with a 2:1 margin. A needle-set variable air cushion at both ends absorbs high-speed impact, and the 1/8" port ensures rapid cycling across the 30 to 800 mm/s speed range.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-50S Is Used
Adjustable Sorting Diverter
Dial in the extend stroke up to 50 mm to route packages of varying sizes on a conveyor without changing the actuator, using the dual air cushions to absorb high-speed impacts.
Vertical Lift Gate
Lift roughly 8 kg of gate payload with a 2:1 safety margin, relying on the 157 N push force and the -S magnet for precise top-position confirmation.
Press Fit Stopper
Set a repeatable forward end position for pressing light components, letting the adjustable cushion decelerate the tooling smoothly before contact.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-50S the Right Cylinder?
If you need less push, the smaller MIJ bumper-only bore lacks this cushioning, making the Ø20 a better choice for smooth stops. For heavier dynamics, stepping up to the Ø25 bore yields 245 N of push at 0.5 MPa. The external stop screw sets the extend end position from 30 to 80 mm 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 to hold a suspended load.
Mount this ISO 6432 mini cylinder using standard LB foot, FA flange, or TC trunnion brackets (SDB pivot blocks are not compatible with this adjustable variant). Select CMSG, DMSG, or EMSG switches to leverage the installed -S magnet.
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 MICJ20X80-50S FAQ
This double-acting cylinder pushes 157 N and pulls 131.9 N at 0.5 MPa, and pushes 219.8 N while pulling 184.7 N at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa. It features a 1/8" air port and an Ø8 mm piston rod with an M8x1.25 male thread.
An external screw shortens the extend stroke by up to 50 mm on site, while the needle-set variable air cushion at both ends decelerates the piston near the ends to soak up high-speed shock. The installed -S magnet allows the use of CMSG, DMSG, or EMSG reed and electronic sensors for position feedback.
