About the Airtac MICJ Adjustable Mini Cylinder MICJ20X160-40
Dial in a precise forward stop on-site without swapping hardware using the AirTAC MICJ20X160-40. This double-acting stainless-steel round-body mini cylinder features an external screw that shortens the extend end position by up to 40 mm, giving a usable forward range of 120 to 160 mm, while the retract stroke remains full. An adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
Built with a stainless barrel and rod for mild corrosion resistance, it drops directly into standard ISO 6432 mini-cylinder brackets. Delivering 157 N of push force at 0.5 MPa, it yields a safe working load of roughly 94 N, or about an 8 kg vertical lift with a 2:1 safety margin. This non-magnet SKU cannot host CMSG, DMSG, or EMSG sensors, and the 1/8" port keeps airflow compact for fast cycling.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X160-40 Is Used
Adjustable Stop Clamping
Clamp parts of varying widths on a single fixture by dialing the extend stop in up to 40 mm, using the 157 N push force to secure components without retooling.
High-Speed Diverter Gate
Rapidly route boxes on a line at speeds up to 800 mm/s while the dual adjustable air cushions absorb the end-of-stroke shock, preventing gate bounce.
Variable Depth Carton Sealing
Extend the rod to press carton flaps, fine-tuning the forward position on the fly for different box depths while maintaining a consistent 94 N safe working load.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X160-40 the Right Cylinder?
When sizing this 20 mm bore, step down to a 16 mm bore if your load is lighter (100.5 N push at 0.5 MPa), or step up to a 25 mm bore (245.3 N push at 0.5 MPa) if you need more thrust. The 40 mm extend adjuster is ideal for fast set-position moves where you need to tune the forward stop after mounting. Remember that the stop screw and air cushion only decelerate the piston near the end of travel; they do not function as a mid-stroke lock. If the machine loses air, the piston will drift, so fit an external rod lock or pilot check valve to hold a suspended load.
Mount this cylinder using LB foot, FA flange, or TC trunnion brackets, along with CA, U, R, or CM back covers. Note that the SDB pivot block is not available on this adjustable-stroke variant. Because this specific SKU lacks the internal magnet, it cannot accept position sensors; choose 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 MICJ20X160-40 FAQ
This 20 mm bore cylinder has a 1/8" air port and an M8x1.25 male rod thread. 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 40 mm on-site, while the needle-set air cushions at both ends decelerate the piston at high speeds. The cylinder does not hold position on air loss, and because this SKU lacks a magnet, it cannot use sensors; the -S version is required for CMSG, DMSG, or EMSG switches.
