About the Airtac MICJ Adjustable Mini Cylinder MICJ20X30-30
Trim the forward stop by up to 30 mm on-site without swapping hardware using this stainless-steel, round-body mini cylinder. The MICJ20X30-30 pairs that adjustable extend stroke with a needle-set air cushion at both ends to absorb high-speed impact, running at 30-800 mm/s on a 1/8" port.
Generating 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. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X30-30 Is Used
Adjustable Stop Clamping
Clamps parts securely with 157 N push force, using the 30 mm extend adjuster to dial in the exact forward stop for varying material thicknesses without changing fixtures.
High-Speed Diverting
Routes small cartons on a conveyor at up to 800 mm/s, relying on the dual adjustable air cushions to decelerate the rod gently and eliminate endcap shock.
Light Press Fit
Performs light-duty press fits for pins or plugs, lifting about 8 kg vertically with a 2:1 safety margin and cushioning the impact at the end of the 30 mm stroke.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X30-30 the Right Cylinder?
For lighter cycles, the Ø16 bore drops to 100.5 N push @0.5 MPa, while heavier setups step up to the Ø25 at 245.3 N. This Ø20 hits a solid middle ground for fast, settable-position moves where the 30 mm extend adjuster and dual air cushions dial in the exact endpoint and decelerate the load smoothly.
The stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve to hold a suspended load. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable here).
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 MICJ20X30-30 FAQ
This double-acting cylinder delivers 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 max of 32 kgf at 1.0 MPa. It features an 8 mm rod, M8x1.25 male rod thread, and a 1/8" air port.
An external screw shortens the extend stroke by up to 30 mm on-site, while a needle valve adjusts the air cushion at both ends to soak up high-speed shock. This SKU has no magnet and cannot take a sensor; you need the -S variant for CMSG/DMSG/EMSG switches.
