Airtac MICJ Adjustable Mini Cylinder MICJ25X75-50
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X75-50 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 75mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-50
Dial in a precise forward stop on-site with the AirTAC MICJ25X75-50, a stainless-steel round-body mini cylinder that shortens the extend stroke by up to 50 mm via an external screw. Usable extend ranges 25-75 mm, while retract remains full. A needle-adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact without swapping hardware.
Built with a 25 mm bore and 10 mm rod, it delivers 245.3 N of push force at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown, and the 1/8" port conforms to the ISO 6432 mounting interface for standard mini brackets. This yields a safe working load of roughly 147 N, or a vertical lift of about 12.5 kg 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 MICJ25X75-50 Is Used
Adjustable Forming Press
Tune the 50 mm extend stop to set precise stamping depth on mild steel, relying on the 245.3 N push force and air cushions to absorb the impact at the bottom of the stroke.
Variable Transfer Diverter
Shift packages on a conveyor by adjusting the extend endpoint on-site without changing cylinder mounts, using the 12.5 kg vertical lift capacity to route varying box sizes.
Calibrated Sealing Head
Dial in the exact forward position for film sealing jaws, letting the needle cushions soak up high-speed shocks while the stainless body handles washdown.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-50 the Right Cylinder?
For lighter pushes, the Ø20 bore provides 157 N at 0.5 MPa; if you need more power, step up to the Ø32 bore at 402 N. The Ø25 hits a sweet spot, and its 50 mm extend adjuster is ideal for fast set-position moves where you need to tune the forward endpoint on the fly. The dual air cushions only decelerate the piston near the stroke end—they do not lock or hold the load mid-stroke.
Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot-block is not available on this adjustable variant). Because this specific code has no -S suffix, it cannot accept position sensors; add the -S option if your cycle requires CMSG, DMSG, or EMSG switches. If the application must hold a load on air loss, install an external rod lock or pilot check valve, as the piston will drift.
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 MICJ25X75-50 FAQ
This 25 mm bore cylinder uses a 1/8" port and delivers 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 stop screw shortens the extend stroke by up to 50 mm (usable extend 25-75 mm), while needle valves adjust the air cushions at both ends to decelerate high-speed moves. This SKU has no magnet and cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches.
