About the Airtac MICJ Adjustable Mini Cylinder MICJ40X20-10S
Trim the forward stop by up to 10 mm on site without swapping cylinders using the AirTAC MICJ40X20-10S. This Ø40 round-body stainless-steel mini cylinder pairs an external extend stop screw with a needle-adjustable air cushion at both ends, letting you dial in the exact 10-20 mm forward position while soaking up high-speed shock.
The stainless barrel and piston rod resist mild corrosion and washdown environments. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing. Note that Ø40 is a non-ISO-6432 size, offering a larger bore in a compact riveted format.

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 MICJ40X20-10S Is Used
High-Speed Diverting
Uses the adjustable air cushion to decelerate the Ø40 piston smoothly at the end of a fast 20 mm stroke, preventing impact damage when routing heavy goods.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X20-10S the Right Cylinder?
For lighter push requirements, the Ø32 bore provides 402.2 N at 0.5 MPa, while the Ø40 shown here is the largest available MICJ size at 628.3 N. The adjustable extend stop and dual air cushions are ideal for fast, repetitive moves where you need to set a precise end position and decelerate smoothly without slamming.
Remember that the stop screw sets the end position but does not lock the piston mid-stroke; the cylinder will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot-block is not available on this adjustable variant).
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 MICJ40X20-10S FAQ
Its theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10 mm, and a needle valve adjusts the air cushion at both ends to absorb high-speed shock. The -S magnet enables CMSG/DMSG/EMSG sensors. The cushion only decelerates near the end of stroke; it does not lock the piston, so the cylinder will drift on air loss.
