About the Airtac MICJ Adjustable Mini Cylinder MICJ25X400-10S
Trim the forward stop by up to 10 mm on site without swapping cylinders, and let the adjustable air cushion at both ends soak up high-speed shock. The AirTAC MICJ25X400-10S is a double-acting, round-body stainless-steel mini cylinder that lets you dial in the exact extend position and control the impact. The external screw shortens the extend end only, giving a usable forward range of 390-400 mm, while the retract stroke remains full.
Built with a stainless barrel and rod for mild washdown resistance, this Ø25 bore unit conforms to the ISO 6432 mounting interface for standard mini brackets. It delivers 245.3 N of push force at 0.5 MPa, translating to a safe working load of about 147 N or a 12.5 kg vertical lift with a 2:1 margin. The 1/8" port and built-in -S magnet support CMSG, DMSG or EMSG sensors for position feedback.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X400-10S Is Used
Adjustable Clamping Press
Dial in the 390-400 mm forward clamp position on the fly to seat varied parts, relying on the 245.3 N push force and end cushioning to prevent impact damage.
High-Speed Divertor
Sort packages at up to 800 mm/s using the 1/8" ported actuator; the adjustable air cushion absorbs the shock of rapid stops while the magnet confirms positioning.
Vertical Lift Gate
Lift roughly 12.5 kg of gate material with a 2:1 safety margin, tweaking the extend stop by up to 10 mm to fine-tune the closed seal without replacing hardware.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X400-10S the Right Cylinder?
When sizing this 25 mm bore, stepping down to a Ø20 MICJ drops the 0.5 MPa push force to 157 N, while stepping up to a Ø32 raises it to 402 N. Choose this model when you need those 245 N of push force combined with a precise, field-adjustable extend stop and high-speed cushioning. The needle cushion decelerates the piston near the end of travel but does not lock or hold the load. If your application must hold position on air loss, add an external rod lock or pilot check valve. Mount via LB foot, FA flange or TC trunnion (SDB is not available), and use the -S magnet with CMSG, DMSG or EMSG switches.
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 MICJ25X400-10S FAQ
This double-acting cylinder uses a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10 mm for a 390-400 mm range, while a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. The -S magnet enables CMSG/DMSG/EMSG sensors. The cushion only decelerates and does not lock; use an external rod lock to hold a load on air loss.
