About the Airtac MICJ Adjustable Mini Cylinder MICJ20X150-20
Trim the forward stop by up to 20 mm on site without swapping hardware using this stainless steel round-body mini cylinder. The external screw shortens the extend end position from 150 mm down to 130 mm, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. As a double-acting actuator, it delivers a push force of 157 N and a pull force of 131.9 N at 0.5 MPa.
Built with a 20 mm bore, an 8 mm piston rod, and a 1/8" port, the riveted stainless construction resists mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for standard mini brackets. This non-magnet SKU cannot host sensors, but the -S variant enables CMSG, DMSG, and EMSG switches. Expect a safe working load around 94 N, which moves about 8 kg vertically with a 2:1 margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X150-20 Is Used
Adjustable Stop Diverter
Fine-tune the 20 mm extend stop to position a diverter gate precisely, using the dual air cushions to absorb shock during high-speed 157 N routing shifts.
Precision Transfer Pusher
Push light parts off a belt at 0.5 MPa, trimming the forward stroke on site to match varying product widths without swapping the cylinder.
Carton Flap Tucker
Tuck flaps at 219.8 N push at 0.7 MPa, relying on the needle-set air cushion to prevent end-of-stroke impact while hitting a dialed-in forward position.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X150-20 the Right Cylinder?
When sizing this 20 mm bore actuator, step down to the 16 mm version if your push requirement falls below 100.5 N at 0.5 MPa, or step up to the 25 mm bore for 245.3 N if the load exceeds the 157 N available here. The 20 mm extend adjustment window is ideal for fast set-position moves where you need to dial in the exact forward stop and rely on the dual air cushions to decelerate the payload smoothly.
Because this is a non-magnet SKU, it cannot take a magnetic sensor; choose the -S suffix if you need CMSG, DMSG, or EMSG switches. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable variant). Remember that the stop screw sets the end position but is not a mid-stroke lock; the cylinder will drift on air loss, so add an external rod lock or pilot check valve for held loads.
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 MICJ20X150-20 FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa it pushes with 219.8 N and pulls with 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (usable extend 130-150 mm), while a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. This non-magnet SKU cannot take sensors. The cushion only decelerates and the stop screw sets the end position; neither acts as a mid-stroke lock, so the piston drifts on air loss.
