Airtac MICJ Adjustable Mini Cylinder MICJ20X300-10S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X300-10S 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 MICJ20X300-10S
Trim the forward stop by up to 10 mm on site without swapping hardware using this AirTAC adjustable-extend mini cylinder. The external screw trims the extend end only (yielding a 290-300 mm usable forward stroke), while a needle-set variable air cushion at both ends soaks up high-speed shock. It is a double-acting, stainless-steel round-body build that resists mild corrosion and washdown.
Fitted with a built-in piston magnet (-S), it supports CMSG, DMSG, and EMSG reed or electronic sensors. The Ø20 mm bore features an M8x1.25 male rod thread and a 1/8" air port. Delivering 157 N of push force at 0.5 MPa, it provides a safe working load of roughly 94 N, or about an 8 kg vertical lift with a 2:1 margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-10S Is Used
Precision Cut-off Stop
Dial in the 10 mm extend stop to set an exact 295 mm blade drop for repetitive material slicing, using the dual air cushions to absorb the high-speed impact at the end of travel.
Divertor Arm Positioning
Perfect for a fast conveyor routing arm: the 157 N push force easily pivots light packages, while the built-in magnet works with DMSG sensors to confirm the extend position.
Carton Flap Tucking
Tuck flaps on moving boxes at speed; the stainless round-body construction handles mild washdown, and the needle-set cushion prevents jarring stops that could tear cardboard.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X300-10S the Right Cylinder?
When sizing this unit, consider the next bore up: the Ø32 delivers 402 N of push at 0.5 MPa for heavier loads, while the smaller Ø16 (which is bumper-only in the MIJ series) provides 100 N. This Ø20 model hits a solid middle ground for fast, settable-position moves where you need to dial in the exact forward stop and rely on the dual-end cushions to decelerate smoothly.
It uses the ISO 6432 mini-cylinder mounting interface, dropping into standard brackets and clevises (LB foot, FA flange, or TC trunnion; note that SDB pivot-blocks are not available on this adjustable variant). Remember that the stop screw sets the end position but is not a mid-stroke lock, and a plain cylinder drifts on air loss—use an external rod lock or pilot check valve if you need 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 MICJ20X300-10S FAQ
This Ø20 mm double-acting cylinder features a 1/8" air port and an Ø8 mm piston rod. 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 10 mm on site (retract remains full). Needle valves adjust the variable air cushion at both ends to decelerate the piston near stroke end. The -S denotes a built-in magnet for CMSG, DMSG, or EMSG sensors.
