About the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-100S
Dial in a precise forward stop on-site with the AirTAC MICJ25X250-100S, a double-acting stainless-steel round-body mini cylinder featuring a 100 mm adjustable extend stroke. An external stop screw trims the forward end position down to a 150 mm usable extend, while the retract stroke remains the full 250 mm. A needle-set variable air cushion at both ends soaks up high-speed shock, letting you set the exact position and control the impact without swapping hardware.
Built with a stainless barrel and piston rod for mild washdown resistance, this Ø25 bore unit pushes with 245.3 N of force at 0.5 MPa (343.4 N at 0.7 MPa). It yields a safe working load of roughly 147 N, moving about 12.5 kg vertically with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors, and the 1/8" port conforms to the ISO 6432 mounting interface for standard mini brackets.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-100S Is Used
Variable Length Diverting
Tunes the extend stroke on the fly to push varying box sizes off a belt without re-mounting hardware, using the 245 N push force to clear parcels efficiently.
Adjustable Carton Sealing
Dials in the exact 150-250 mm forward stop for different flap heights, while the dual air cushions prevent denting the cardboard at high cycling speeds.
Sensor-Checked Clamping
Uses the built-in magnet with a DMSG sensor to verify clamp position on mild-steel parts, relying on the 12.5 kg safe lift margin for secure holding.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-100S the Right Cylinder?
When sizing this unit, step down to the Ø20 bore for lighter loads (157 N push at 0.5 MPa) or step up to the Ø32 bore for heavier cycles (402 N push at 0.5 MPa). The Ø25 hits a solid middle ground, and the 100 mm extend adjuster is ideal for fast set-position moves where you need to tune the forward stop on the fly. The dual adjustable cushions absorb end-of-stroke kinetic energy at speeds up to 800 mm/s.
Remember the stop screw sets the end position but is not a mid-stroke lock; the piston will drift 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 not available on this adjustable variant). The -S magnet enables position sensing with CMSG, DMSG, or EMSG switches.
Quick checklist

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 MICJ25X250-100S FAQ
This double-acting cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 100 mm on-site (usable extend 150-250 mm), while the retract remains full. Needle-set variable air cushions at both ends decelerate the piston near stroke end to absorb shock. The -S magnet enables CMSG, DMSG, and EMSG sensors for position feedback.
