About the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-20
Trim the forward stop by up to 20 mm on site without swapping hardware using the AirTAC MICJ25X75-20. This double-acting round-body mini cylinder pairs that extend adjuster with a needle-set variable air cushion at both ends to soak up high-speed shock.
Built with a stainless-steel barrel and Ø10 mm rod for mild washdown resistance, it conforms to the ISO 6432 mounting interface and uses a 1/8" port. Delivering 245.3 N of push force at 0.5 MPa, it yields a safe working load of about 147 N, or roughly a 12.5 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-20 Is Used
Dial-In Clamping
Securely clamp varied parts using the 20 mm extend adjuster to set exact forward positions, relying on 245 N of push force for a firm grip.
High-Speed Diverting
Rapidly route lightweight boxes on a belt line; the dual adjustable air cushions absorb the shock of fast 75 mm strokes at the end of travel.
Carton Stopper
Halt corrugated cartons precisely at a packing station, fine-tuning the stop screw on site to accommodate different package widths without changing cylinders.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-20 the Right Cylinder?
When sizing within the MICJ family, step down to the Ø20 bore for 157 N push @0.5 MPa if your load is lighter, or step up to the Ø32 bore for 402 N push @0.5 MPa when you need more thrust. The Ø25 hits a solid middle ground, and its 20 mm extend stop screw is ideal for fast set-position moves where you need to dial in the forward endpoint precisely.
The adjustable air cushion only decelerates the piston near the stroke end; it is not a mid-stroke lock or brake. If the application must hold a load on air loss, add an external rod lock or pilot-operated check valve. For mounting, use LB foot, FA flange or TC trunnion brackets (the SDB pivot block is not offered on this adjustable variant).
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 MICJ25X75-20 FAQ
This 25 mm bore cylinder uses a 1/8" port and a 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 stop screw shortens the extend stroke by up to 20 mm (usable extend 55-75 mm), while retract remains full. Needle valves adjust the variable air cushion at both ends to decelerate the piston near stroke end. This SKU has no magnet and cannot take sensors; the -S variant adds a magnet for CMSG/DMSG/EMSG switches.
