Airtac MICJ Adjustable Mini Cylinder MICJ20X100-75S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X100-75S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 100mm 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 MICJ20X100-75S
Trim the forward stop by up to 75 mm on site without swapping hardware using this stainless-steel round-body mini cylinder. The MICJ20X100-75S pairs that external extend adjuster with a needle-set variable air cushion at both ends to soak up high-speed shock, letting you dial in the exact 25-100 mm forward position while controlling impact. Driven by a 1/8" port and an 8 mm rod, it delivers 157 N of push force at 0.5 MPa.
The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for precise end-of-stroke sensing. Conforming to the ISO 6432 mounting interface for easy bracket drops, the stainless barrel and rod shrug off mild washdown corrosion. Expect a safe working load around 94 N, which translates to lifting roughly 8 kg vertically with a 2:1 safety margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X100-75S Is Used
Adjustable Forming Stop
Dial in a precise 25-100 mm extend strike on a light stamping or forming press, relying on the dual air cushions to absorb the high-speed impact at the end of each cycle.
Variable Transfer Diverter
Act as a routing gate on a packaging line, adjusting the extend length on the fly to accommodate different carton sizes while lifting roughly 8 kg of product safely.
Washdown Pusher Arm
Push bins or totes into a washdown station where the stainless barrel resists mild corrosion, using the magnet for CMSG position confirmation at the retracted home spot.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X100-75S the Right Cylinder?
At 0.5 MPa this 20 mm bore generates 157 N push and 131.9 N pull. If your payload is lighter, the 16 mm bore offers 100.5 N push; if you need more muscle, step up to the 25 mm bore for 245.3 N push. Choose this adjustable-stroke variant when a machine cycle needs a fast set-position move and on-site tuning of the extend endpoint without machining new spacers.
The stop screw sets the extend end position but is not a mid-stroke lock, and the air cushion only decelerates near the stroke end, so the piston will drift if air pressure drops. For vertical or suspended loads that must hold position on air loss, add an external rod lock or pilot-operated check valve. Mount via LB foot, FA flange or TC trunnion (SDB pivot-block is unavailable here), and route your reed or electronic sensors along the groove.
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 MICJ20X100-75S FAQ
This 20 mm bore cylinder uses a 1/8" port. At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 75 mm (usable range 25-100 mm), while retract remains full. Needle valves adjust the variable air cushion at both ends to decelerate the piston near the ends. The -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG sensors.
