About the Airtac MICJ Adjustable Mini Cylinder MICJ20X30-20S
Dial in a precise forward stop on-site with the AirTAC MICJ20X30-20S, a stainless-steel round-body mini cylinder that lets you shorten the extend stroke by up to 20 mm via an external screw. The built-in magnet enables position sensing, while adjustable air cushions at both ends soak up high-speed shock. It delivers a solid 157 N push force at 0.5 MPa, yielding a safe working load of roughly 94 N or a vertical lift capacity of about 8 kg with a 2:1 margin.
Built with a corrosion-resistant stainless barrel and rod, this double-acting unit conforms to the ISO 6432 mounting interface for straightforward bracket integration. It features an 8 mm piston rod, an M8x1.25 male rod thread, and a 1/8" air port. The cushion needle ensures smooth deceleration near stroke end, though it acts purely as a shock absorber rather than a mid-stroke lock.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X30-20S Is Used
Dial-In Clamping Press
Securely clamps delicate electronic housings, using the 20 mm extend adjustment to set the exact forward stop and the air cushion to prevent impact damage at fast cycle speeds.
Dynamic Divert Gate
Routes lightweight packages on a line by extending a 94 N working load, relying on the adjustable stop to fine-tune the gate angle without swapping hardware.
Vertical Flap Folder
Folds carton flaps at high speed, using the needle-set cushion to decelerate the 8 kg vertical lift smoothly before the end of stroke, avoiding jarring stops.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X30-20S the Right Cylinder?
When sizing this 20 mm bore, compare it directly against adjacent options: the smaller 16 mm bore provides 100.5 N push at 0.5 MPa, while stepping up to the 25 mm bore yields 245.3 N. Choose this model when you need 157 N of push force combined with on-the-fly extend position tuning and high-speed cushioning. The external screw adjusts the forward end position only and does not function as a mid-stroke lock; if your application must hold a load vertically during air loss, install an external pilot check valve or rod lock.
Mounting flexibility includes LB foot, FA flange, and TC trunnion styles, but note the SDB pivot block is not offered on this adjustable variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for precise end-of-stroke detection.
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 MICJ20X30-20S FAQ
This 20 mm bore cylinder features a 1/8" air port and delivers 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm, while the needle-set air cushion at both ends decelerates the piston near stroke end. The -S suffix means a magnet is included for CMSG/DMSG/EMSG sensors. The cushion only absorbs shock and does not lock the piston; the cylinder will drift on air loss, so use an external rod lock for holding.
