About the Airtac MICJ Adjustable Mini Cylinder MICJ20X40-10S
Dial in a precise forward stop on-site with the AirTAC MICJ20X40-10S, a stainless-steel round-body mini cylinder featuring a 10 mm extend-stroke adjuster and variable air cushions at both ends. The external screw trims the extend end position down to 30 mm without swapping cylinders, while the needle cushions soak up high-speed shock. Driven by a 1/8" port and an Ø8 rod, this double-acting actuator delivers 157 N of push force at 0.5 MPa.
Built with a mildly corrosion-resistant stainless barrel and rod, it conforms to the ISO 6432 mounting interface for straightforward bracket drops. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for position feedback. With a safe working load around 94 N, it easily moves roughly 8 kg vertically with a 2:1 safety margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X40-10S Is Used
Light Part Clamping
Clamp delicate aluminum housings securely. The 10 mm extend adjuster lets you dial in the exact 35 mm forward stop, while the air cushion prevents harsh impacts on the part.
Package Diverting
Push light cartons off a conveyor line. Delivering 157 N of push force, this cylinder handles roughly 8 kg loads safely and retracts fully to clear the belt path.
Fill Station Gating
Control the flow of empty bottles into a fill station. The built-in magnet works with DMSG sensors to verify gate position, and the cushions absorb high-speed cycling shock.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X40-10S the Right Cylinder?
When sizing this 20 mm bore, dropping down to a 16 mm variant limits you to 100.5 N of push force at 0.5 MPa, whereas stepping up to a 25 mm bore yields 245.3 N. The MICJ20X40-10S hits the sweet spot for fast, settable-position moves, letting you tune the 30-40 mm extend window and use the dual-end cushions to prevent endcap impact. Remember that the stop screw sets the end position but does not act as a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for suspended loads.
Mount using standard LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not offered on this adjustable variant). Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for precise stroke confirmation.
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 MICJ20X40-10S FAQ
This 20 mm bore cylinder uses a 1/8" port and an Ø8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, or 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 10 mm on-site, giving a usable 30-40 mm forward range. The needle-adjustable air cushions at both ends only decelerate the piston near the stroke end to absorb shock; they do not lock or hold the load. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
