About the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-20
Dial in a precise forward stop on-site with the AirTAC MICJ20X80-20, a double-acting stainless-steel round-body mini cylinder. An external screw trims the extend end position by up to 20 mm, giving a usable forward range of 60 to 80 mm without swapping hardware. The retract stroke remains the full 80 mm. A needle-set variable air cushion at both ends absorbs high-speed shock, letting you set the exact position and control the impact.
Built with a stainless barrel and rod for mild washdown resistance, this Ø20 bore model pushes with 157 N at 0.5 MPa. It yields a safe working load of roughly 94 N, moving about 8 kg vertically with a 2:1 margin. It uses the ISO 6432 mounting interface for standard mini brackets and features a 1/8" port. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-20 Is Used
Light Parts Ejection
Ejects small molded components at speed, using the 20 mm extend trim to hit the exact drop point while the dual air cushions absorb the impact of the 8 kg load.
Package Diverter
Pushes light cartons off a belt with 157 N of push force at 0.5 MPa, relying on the adjustable forward stop to accommodate varying box widths without retooling.
Film Feed Tensioning
Feeds packaging film in a 60 to 80 mm window, using the on-site extend adjustment to fine-tune the stroke length and the needle cushions to prevent snapping at high speeds.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-20 the Right Cylinder?
When sizing, step down to the Ø16 bore for lighter loads (100.5 N push at 0.5 MPa) or up to the Ø25 bore for heavier tasks (245.3 N push at 0.5 MPa). Choose this Ø20 model for fast, settable-position moves where the 20 mm extend trim and dual adjustable air cushions prevent harsh end-strikes. Mount via LB foot, FA flange, or TC trunnion; the SDB pivot-block is not available on this adjustable variant.
Remember the stop screw sets the end position but is not a mid-stroke lock. The air cushion only decelerates near the stroke end. If you need to hold a load on air loss, add an external rod lock or pilot-operated check valve, as the piston will drift.
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 MICJ20X80-20 FAQ
This double-acting cylinder delivers 157 N push and 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa. It features a 1/8" air port and an M8x1.25 male rod thread.
An external screw shortens the extend end position by up to 20 mm on-site, letting you set the forward stop without changing the cylinder. The needle-set variable air cushion at both ends decelerates the piston near the ends to soak up high-speed shock. This SKU has no magnet, so it cannot take position sensors; the -S variant is required for CMSG/DMSG/EMSG switches.
