Airtac MICJ Adjustable Mini Cylinder MICJ20X125-10
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X125-10 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 125mm 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 MICJ20X125-10
Dial in the forward stop on site without swapping cylinders: the AirTAC MICJ20X125-10 uses an external screw to shorten the extend end position by up to 10 mm, giving a usable forward range of 115-125 mm. This stainless-steel, round-body mini cylinder pairs that settable stop with an adjustable air cushion at both ends, soaking up high-speed shock so you control both the impact and the position. It delivers 157 N of push force at 0.5 MPa.
Built with a stainless barrel and rod for mild corrosion and washdown resistance, this double-acting unit runs at 30-800 mm/s and uses a 1/8" port. It yields a safe working load of about 94 N (roughly 60% of the 0.5 MPa push figure), making it suitable for moving vertical loads around 8 kg with a 2:1 margin. It conforms to the ISO 6432 mounting interface for standard mini brackets.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X125-10 Is Used
Precision Component Seating
Trim the extend stroke by up to 10 mm to seat delicate electronic parts perfectly, while the dual air cushions absorb shock during fast 157 N push operations.
Package Diverter Stop
Set an exact 115-125 mm forward stop to deflect light cartons on a line, relying on the stainless construction for washdown resistance in packaging zones.
Vertical Lift Dampening
Lift roughly 8 kg loads vertically and use the adjustable air cushion to decelerate the payload smoothly at the end of the stroke without harsh impacts.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X125-10 the Right Cylinder?
When sizing, step down to the Ø16 bore for lighter 100 N push tasks, or move up to the Ø25 bore if you need 245 N of push at 0.5 MPa. The MICJ20X125-10 shines in fast set-position moves where the 10 mm extend adjuster and needle-set air cushions tame end-of-stroke shock. For mounting, use LB foot, FA flange, or TC trunnion brackets (the SDB pivot-block is not available on this adjustable variant). Because this SKU lacks the -S magnet, it cannot take CMSG, DMSG, or EMSG sensors. Note that 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.
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 MICJ20X125-10 FAQ
This double-acting cylinder uses a 1/8" port and delivers a push of 157 N and a pull of 131.9 N at 0.5 MPa. At 0.7 MPa, push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10 mm, while the needle-set air cushion at both ends decelerates the piston near stroke end to absorb shock. This cylinder has no -S magnet, so it cannot take sensors. The cushion only decelerates and does not lock; the piston drifts on air loss, so use an external rod lock to hold a load.
