About the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20
Trim the forward stop by up to 20 mm on site without swapping hardware using this AirTAC MICJ40X60-20 round-body mini cylinder. The external screw shortens the extend end position, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. This stainless-steel, riveted construction resists mild corrosion and washdown environments.
As a double-acting actuator, it delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. This yields a safe working load of roughly 377 N, moving about 32 kg vertically with a 2:1 margin. The 1/4" port and M12x1.25 male rod thread handle robust flow, and because this SKU lacks a magnet, it cannot accept CMSG, DMSG, or EMSG sensors.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20 Is Used
Heavy Clamping
Dial in the 60 mm extend stroke up to 20 mm shorter to clamp heavy steel billets securely, relying on the 628.3 N push force.
Product Diversion
Absorb the impact of fast 32 kg package diverting using the adjustable air cushion at stroke end, preventing mechanical shock.
Washdown Sealing
Press carton seals in damp environments using the stainless-steel barrel and rod, which resist mild corrosion during washdown cycles.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20 the Right Cylinder?
When sizing this 40 mm bore, step down to the MICJ32 (563.0 N push @0.5 MPa) for lighter loads, or step up to a larger non-mini profile if you exceed the 879.6 N push @0.7 MPa. The 20 mm extend adjuster is ideal for fast set-position moves where you need precise forward placement without machining spacers.
The stop screw sets the end position but is not a mid-stroke lock; the piston drifts on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable), and note that this non-magnet SKU cannot take a sensor.
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 MICJ40X60-20 FAQ
This double-acting cylinder pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical max force is 128.1 kgf at 1.0 MPa. It uses a 1/4" air port.
An external screw shortens the extend stroke by up to 20 mm on site, letting you set the forward stop without swapping cylinders. An adjustable air cushion at both ends decelerates the piston near stroke end to absorb high-speed shock. This SKU has no magnet, so it cannot take sensors.
