About the Airtac MICJ Adjustable Mini Cylinder MICJ20X20-10S
Dial in a precise forward stop on-site with the AirTAC MICJ20X20-10S, a double-acting round-body mini cylinder featuring an external screw that shortens the extend stroke by up to 10 mm. The usable extend range becomes 10-20 mm, letting you set the exact end position without swapping hardware. A needle-adjustable air cushion at both ends soaks up high-speed shock, ensuring smooth deceleration rather than a hard impact.
Built with a stainless-steel barrel and piston rod, this riveted construction resists mild corrosion and washdown environments. The Ø20 mm bore delivers 157 N of push force at 0.5 MPa, translating to a safe working load of about 94 N or a vertical lift of roughly 8 kg with a 2:1 safety margin. It uses a standard 1/8" port and conforms to the ISO 6432 mounting interface for easy bracket interchangeability. The -S suffix indicates a built-in piston magnet, ready for CMSG, DMSG, or EMSG position sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X20-10S Is Used
Dial-In Clamping Press
Use the 10 mm extend adjustment to set an exact clamping depth on delicate parts, relying on the 157 N push force to secure components without crushing them.
High-Speed Diverter Arm
Tune the needle air cushions to absorb shock during rapid 30-800 mm/s sorting movements, preventing bounce when the arm reaches its forward stop.
Washdown Flap Opener
Leverage the stainless steel construction and 1/8" port to actuate packaging flaps in mildly corrosive environments, lifting roughly 8 kg safely.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X20-10S the Right Cylinder?
When sizing this actuator, the 157 N push force at 0.5 MPa suits light-duty positioning tasks. If you need less force, the smaller Ø16 bore provides 100.5 N push, while stepping up to the Ø25 bore yields 245.3 N for heavier loads. The adjustable extend stop and dual air cushions are ideal for fast, repeatable set-position moves where you must tune out end-of-stroke shock. For mounting, use LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not available on this adjustable variant).
Remember that the stop screw sets the forward end position only; it is not a mid-stroke lock. The cylinder does not hold a load on air loss—the piston will drift. For suspended loads, integrate an external rod lock or pilot-operated check valve. Because this is the -S variant, you can directly mount CMSG, DMSG, or EMSG sensors for position feedback.
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 MICJ20X20-10S FAQ
This Ø20 mm bore cylinder uses a 1/8" air port. At 0.5 MPa it provides 157 N push and 131.9 N pull force. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10 mm (usable range 10-20 mm), setting the forward end position without affecting full retract. Needle valves adjust the air cushion at both ends to decelerate the piston near stroke end. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. The cushion decelerates but does not lock the load.
