About the Airtac MICJ Adjustable Mini Cylinder MICJ20X225-20
Trim the forward stop by up to 20 mm on site without swapping hardware using this AirTAC adjustable-extend mini cylinder. The external screw sets the extend end position between 205 and 225 mm, while the needle-set air cushions at both ends soak up high-speed shock. It is a double-acting, stainless-steel round-body unit with an 8 mm rod and a 1/8" port.
Delivering 157 N of push force at 0.5 MPa, it handles a safe working load of roughly 94 N or lifts about 8 kg vertically with a 2:1 margin. The Ø20 body conforms to the ISO 6432 mounting interface for standard mini brackets. Because this SKU lacks a magnet, it cannot take CMSG, DMSG, or EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X225-20 Is Used
Dial-In Clamping Stop
Clamp delicate parts by tuning the extend stop down 20 mm, letting the 157 N push force seat the component while the air cushion prevents impact damage.
High-Speed Diverting
Divert light packages on a belt by setting a precise 210 mm extend position and relying on the adjustable cushion to absorb shock at fast cycle speeds.
Vertical Lift Stop
Lift an 8 kg tote by setting the forward stop to clear an obstacle, using the full 225 mm retract and the cushion to soften the landing.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X225-20 the Right Cylinder?
If you need less force, the Ø16 bore provides 100.5 N push at 0.5 MPa; if your load is heavier, the Ø25 bore offers 245.3 N. This Ø20 model is ideal when you need to dial in a precise extend position on the fly and rely on the dual-end air cushions to decelerate smoothly at high speeds. Note that the stop screw only sets the end position—it is not a mid-stroke lock.
For mounting, you can use LB foot, FA flange, or TC trunnion brackets, but SDB pivot blocks are not available on this adjustable variant. If the application requires position sensing, you must select the -S magnet version to use CMSG, DMSG, or EMSG switches. Because a standard cylinder drifts on air loss, add an external rod lock or pilot check valve if you need to hold a suspended load.
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 MICJ20X225-20 FAQ
This Ø20 bore cylinder features a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm, giving a usable forward range of 205-225 mm. Needle valves adjust the air cushions at both ends to decelerate high-speed moves. This cylinder cannot hold a load on air loss and this SKU lacks a magnet for sensors.
