About the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-100
Dial in a precise forward stop on-site with the AirTAC MICJ20X300-100, a stainless-steel round-body mini cylinder featuring a 100 mm extend-stroke adjuster. The external stop screw trims the forward end position down from the 300 mm nominal maximum to any point between 200 and 300 mm, while the retract stroke remains full length. A needle-set variable air cushion at both ends absorbs high-speed impact, letting you set the position and control the end-of-stroke shock simultaneously.
Built with a corrosion-resistant stainless barrel and Ø8 mm rod, this double-acting ISO 6432 mounting-interface unit pushes with 157 N of force at 0.5 MPa (219.8 N at 0.7 MPa). It yields a safe working load of roughly 94 N, capable of vertically lifting about 8 kg with a 2:1 safety margin. The 1/8" port feeds the 30-800 mm/s speed range. Note this SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-100 Is Used
Variable-Length Ejector
Tunes the extend stroke from 200 to 300 mm to push varied box sizes off a belt without repositioning the cylinder, using the air cushion to halt the 8 kg load smoothly.
Adjustable Flap Folder
Sets a precise forward stop to fold carton flaps of differing heights at high speed, relying on the needle cushion to absorb impact at the end of the 219.8 N push.
Light-Press Positioning
Dials in the exact extend end-point for pressing small components, leveraging the 100 mm adjustment window and mild washdown resistance of the stainless steel build.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-100 the Right Cylinder?
For lighter tasks, the Ø16 bore provides 100.5 N push at 0.5 MPa but lacks the 100 mm adjuster window of this unit; for heavier loads, stepping up to the Ø25 bore yields 245.3 N. Choose this Ø20 model when you need fast, settable-position moves and repeatable forward stops without swapping cylinders. The adjustable air cushion is strictly for deceleration near the end of travel—it is not a mid-stroke lock or brake. If the application requires holding a load on air loss, install an external rod lock or pilot-operated check valve, as the piston will drift.
Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot-block is not available on adjustable-stroke variants). Back covers CA, U, R, and CM are offered. Because this specific SKU is non-magnetic, it cannot support position sensing; order the -S variant if you require 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 MICJ20X300-100 FAQ
This double-acting cylinder uses a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 100 mm on-site (usable range 200-300 mm), while the retract stroke remains fixed. A needle-set variable air cushion at both ends decelerates the piston near the end of travel to absorb high-speed shock. This SKU has no magnet, so it cannot accept sensors; the -S variant is required for CMSG/DMSG/EMSG switches.
