About the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-20S
Dial in a precise forward stop on-site with the AirTAC MICJ40X160-20S, a round-body stainless steel mini cylinder featuring a 20 mm adjustable extend stroke. An external stop screw lets you trim the forward end position from 140 to 160 mm without swapping hardware, while the needle-set air cushion at both ends absorbs high-speed impact. As a double-acting actuator, it delivers substantial force, pushing with 628.3 N and pulling with 527.8 N at 0.5 MPa.
Built with a corrosion-resistant stainless barrel and rod, this unit handles mild washdown environments and operates at speeds from 30 to 800 mm/s. The 1/4" port and M12x1.25 male rod thread accommodate robust plumbing and mounting. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG sensors for position feedback.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-20S Is Used
Heavy Package Diverter
Pushes heavy cartons off a main line at high speed, using the 20 mm extend trim to match the diverter angle and the air cushion to prevent end-impact slamming.
Pallet Flap Folding
Folds large cardboard flaps on oversized pallets, dialing in the exact 145 mm forward position needed to clear the load without crushing the box.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-20S the Right Cylinder?
The combination of an adjustable forward stop and dual air cushions makes it ideal for fast, repetitive moves where you need to set a precise endpoint and decelerate heavy loads smoothly. Note that the stop screw only sets the extend end position; it is not a mid-stroke lock. The air cushion merely decelerates the piston near the end of travel and does not function as a brake.
For mounting, you can utilize LB foot, FA flange, or TC trunnion brackets, along with CA, U, R, or CM back covers, but the SDB pivot block is not available on this adjustable variant. If your application requires the load to remain fixed during a loss of air pressure, you must add an external rod lock or a pilot-operated check valve, as the piston will drift. The built-in magnet allows seamless integration of CMSG, DMSG, or EMSG switches for exact positioning.
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 MICJ40X160-20S FAQ
This 40 mm bore cylinder features a 1/4" air port. At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm on-site, while the needle-set air cushion at both ends decelerates the piston near the end of travel to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. The cushion and stop screw do not lock the piston; for holding a load on air loss, use an external rod lock or pilot check valve.
