About the Airtac MICJ Adjustable Mini Cylinder MICJ20X90-10S
An external stop screw trims the forward end position by up to 10 mm on this 20 mm bore round-body mini cylinder, letting you dial in the extend stop from 80 to 90 mm without swapping units. Needle-adjustable air cushions at both ends absorb high-speed impact, so you can set the position and control the deceleration in one compact stainless package.
With a 157 N push force at 0.5 MPa, this double-acting cylinder moves about 8 kg vertically with a 2:1 safety margin. The stainless barrel and rod resist mild corrosion, and the built-in -S magnet enables CMSG, DMSG, or EMSG position sensors. Ports are 1/8" PT or G, and the M8x1.25 male rod thread suits standard ISO 6432 mini-cylinder brackets.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X90-10S Is Used
Set-Position Stops
Adjust the forward stop by up to 10 mm on the fly for quick changeovers in packaging guides or fixture stops, without disassembling the cylinder.
High-Speed Indexing
The adjustable cushion at both ends lets you tune deceleration on fast 90 mm indexing moves, protecting light payloads up to 8 kg from end-of-stroke shock.
Washdown Zone Pushers
Stainless barrel and rod resist mild washdown exposure while the 157 N push handles light pusher duties in food or pharmaceutical secondary packaging.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X90-10S the Right Cylinder?
This 20 mm bore unit delivers 157 N push and 131.9 N pull at 0.5 MPa. If you need more force, step up to the 25 mm bore MICJ25X90-10S with 245.3 N push; if space is tighter, the 16 mm bore MICJ16X90-10S offers 100.5 N push. The 10 mm adjustable stroke suits fast set-position moves where you repeatedly change the forward stop.
Remember, the stop screw sets the extend end position only - it is not a mid-stroke lock. For holding loads on air loss, add an external rod lock or pilot-operated check valve. The -S magnet enables CMSG/DMSG/EMSG sensors. SDB pivot-block mounting is not available on this adjustable-stroke model; use LB foot, FA flange, or TC trunnion.
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 MICJ20X90-10S FAQ
At 0.5 MPa, push is 157 N and pull is 131.9 N. At 0.7 MPa, push is 219.8 N and pull is 184.7 N. Theoretical maximum force is 32 kgf at 1.0 MPa. Safe working load is about 94 N (60% of the 0.5 MPa push force).
The external stop screw shortens the extend end by up to 10 mm, giving a usable extend of 80-90 mm; retract is always full. The adjustable air cushions at both ends use needles to control deceleration near stroke end. The -S magnet enables CMSG, DMSG, or EMSG sensors. This is not a mid-stroke lock - for holding loads, use an external rod lock.
