About the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-75S
Dial in a precise forward stop without swapping hardware using the AirTAC MICJ20X300-75S. This double-acting round-body mini cylinder features an external screw that shortens the extend stroke by up to 75 mm on site, giving a usable forward range of 225-300 mm, while an adjustable air cushion at both ends soaks up high-speed shock.
Built with a stainless-steel barrel and rod for mild washdown resistance, the Ø20 bore conforms to the ISO 6432 mounting interface. It delivers 157 N of push force at 0.5 MPa, translating to a safe working load of roughly 94 N or a 2:1 vertical lift of about 8 kg. The -S suffix means a built-in piston magnet is present for CMSG, DMSG or EMSG sensors, and the 1/8" port ensures standard pneumatic plumbing.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-75S Is Used
Adjustable Clamping Press
Securely clamps 8 kg metal parts at high speed, using the 75 mm extend trim to dial in the exact contact position and the air cushion to prevent impact marking.
Variable Stopper Gate
Acts as a pneumatic stop on a packaging line, extending 225-300 mm to halt cartons of varying sizes while absorbing the kinetic shock of fast-moving items.
Vertical Lift Diverter
Diverts lightweight totes upward against gravity, leveraging the 157 N push force and the stainless construction to handle mildly humid warehouse environments.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-75S the Right Cylinder?
When sizing this unit, compare it directly against adjacent bores: the smaller Ø16 lacks air cushions (MIJ bumper type, 100.5 N push @0.5 MPa), while the larger Ø25 steps up significantly to 245.3 N push @0.5 MPa. Choose the Ø20 when your payload is around 8 kg and you need fine-tuned deceleration.
The external stop screw and needle valves are designed for fast set-position moves, but note this cylinder does not hold position on air loss—the piston drifts, and the cushion only decelerates near the end of travel. For a held load, add an external rod lock or pilot check valve. Mount via LB foot, FA flange or TC trunnion (SDB pivot-block is not available on this adjustable variant), and match your CMSG/DMSG/EMSG switches to the -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 MICJ20X300-75S FAQ
This Ø20 mm double-acting cylinder uses a 1/8" air port and an M8x1.25 male rod thread. 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 stop screw shortens the extend end position by up to 75 mm on site, while the retract stroke remains full. The adjustable air cushions at both ends use needle valves to decelerate the piston near the ends, soaking up high-speed shock. The -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG sensors.
