Airtac MICJ Adjustable Mini Cylinder MICJ20X300-20
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X300-20 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 300mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-20
Dial in a precise forward stop on-site with the AirTAC MICJ20X300-20, a stainless-steel round-body mini cylinder that shortens the extend stroke by up to 20 mm via an external screw. You get a usable forward range of 280-300 mm, letting you set exact end positions without swapping hardware. It pairs this settable stop with a needle-adjustable air cushion at both ends to soak up high-speed shock.
Built with a corrosion-resistant stainless barrel and rod, this double-acting ISO 6432 unit uses an M8x1.25 male rod thread and a 1/8" port. It delivers 157 N of push force at 0.5 MPa, yielding a safe working load of about 94 N or a vertical lift of roughly 8 kg with a 2:1 margin. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-20 Is Used
Divert Gate Actuation
Sets a precise 285 mm extend stroke to nudge light packages onto a branch line, using the dual air cushions to absorb impact at 800 mm/s.
Light Press Assembly
Pushes a 9 kg jig into place with 157 N of force, relying on the 20 mm external stop to fine-tune the contact position without reprogramming.
Film Feed Tensioning
Extends to a dialed-in forward stop to maintain consistent packaging film tension, while the stainless construction resists mild washdown moisture.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-20 the Right Cylinder?
When sizing this 20 mm bore, compare it directly against adjacent bores: the smaller Ø16 pushes 100.5 N at 0.5 MPa, while the larger Ø25 pushes 245.3 N. Choose the MICJ20X300-20 when your fast, repetitive moves need both a dialed-in forward stop and shock absorption. The external screw and needle cushions only trim the extend end position and decelerate near stroke end—they do not lock the piston mid-stroke. If the load must hold position on air loss, add an external rod lock or pilot check valve.
Mount this cylinder using LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not available on this adjustable variant). Because this non-S SKU has no magnet, position sensing is impossible here; upgrade to the -S variant if your application requires CMSG, DMSG, or EMSG switches.
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 MICJ20X300-20 FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 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 screw shortens the extend stroke by up to 20 mm on-site, giving a 280-300 mm forward range. Needle valves adjust the air cushions at both ends to decelerate the piston before impact. This SKU has no magnet, so it cannot accept position sensors.
