Airtac MICJ Adjustable Mini Cylinder MICJ20X250-75S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X250-75S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 250mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments.

About the Airtac MICJ Adjustable Mini Cylinder MICJ20X250-75S
Dial in the forward stop without swapping hardware: the AirTAC MICJ20X250-75S uses an external screw to shorten the extend end by up to 75 mm on site, giving a usable forward range of 175-250 mm. This double-acting, round-body stainless-steel mini cylinder pairs that set-position flexibility with an adjustable air cushion at both ends to soak up high-speed shock.
Driven by a 20 mm bore and a 1/8" port, it delivers 157 N of push force at 0.5 MPa, translating to a safe working load of about 94 N or a 2:1 vertical lift capacity near 8 kg. The stainless barrel and piston rod resist mild corrosion and washdown, and the built-in magnet (-S) supports CMSG, DMSG and EMSG position sensing. It conforms to the ISO 6432 mounting interface for straightforward bracket integration.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X250-75S Is Used
Tuned Clamping Press
Clamp parts securely using the 157 N push force, dialing the extend stroke down by 75 mm to accommodate varying material thicknesses without changing tooling.
High-Speed Divertor
Rapidly route packages on a line at up to 800 mm/s, relying on the adjustable air cushions to absorb end-of-stroke shock and prevent bounce.
Vertical Lift Gate
Raise and lower an 8 kg access gate, using the external stop screw to set the precise open height limit for the workflow.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X250-75S the Right Cylinder?
When sizing this unit, consider the force bracket: stepping down to a 16 mm bore drops the 0.5 MPa push force to 100.5 N, while moving up to a 25 mm bore raises it to 245.3 N. The 75 mm extend trim and dual cushion needles are ideal for fast, repetitive set-position moves where you need to tune the forward impact without re-engineering the cell.
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 suspended loads. Mount via LB foot, FA flange or TC trunnion (the SDB pivot block is not offered on this adjustable variant), and use CMSG/DMSG/EMSG switches with the -S magnet.
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 MICJ20X250-75S FAQ
This 20 mm bore cylinder features a 1/8" 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 force of 32 kgf at 1.0 MPa.
The external screw shortens the extend stroke only by up to 75 mm, while the needle-set air cushion at both ends decelerates the piston near stroke ends to absorb shock. The -S indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors; the cushion decelerates but does not lock or hold the load.
