Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 300mm 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 MICJ25X300-75
Dial in a precise forward stop on site with the AirTAC MICJ25X300-75, a stainless-steel round-body mini cylinder that shortens the extend stroke by up to 75 mm via an external screw. This 25 mm bore, double-acting actuator delivers 245.3 N of push force at 0.5 MPa, while needle-adjustable air cushions at both ends soak up high-speed shock to protect your tooling. It uses the ISO 6432 mounting interface for straightforward bracket integration.
The external stop screw sets the extend end position anywhere between 225 mm and the 300 mm maximum, but it is not a mid-stroke lock. This SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors; choose the -S variant if you require position detection. With a 1/8" port and a 1.0 MPa maximum pressure, it provides a safe working load of roughly 147 N, moving about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75 Is Used
Adjustable Stroke Clamping
Secure varying part widths on a single fixture by dialing the extend stop up to 75 mm shorter, using the 245.3 N push force to hold components firmly during machining.
High-Speed Diverting
Rapidly route packages down a line at speeds up to 800 mm/s while the dual adjustable air cushions absorb end-of-stroke impact, preventing premature wear on the diverter arm.
Variable Depth Sealing
Press carton flaps at different depths without changing cylinders, tuning the forward endpoint on site to match box heights while the 1/8" port maintains responsive airflow.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75 the Right Cylinder?
When sizing this 25 mm bore, step down to a 20 mm MICJ if your load requires less than 157 N of push at 0.5 MPa, or move up to a 32 mm bore for 402.2 N when overcoming heavy friction. The adjustable extend stop and dual air cushions shine in fast set-position moves where you must tune the forward endpoint without swapping hardware. Remember that the stop screw and cushions only decelerate the piston near stroke end; they do not hold the load on air loss. For vertical or suspended loads, add an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not offered), and note this non-magnet SKU cannot take a sensor.
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 MICJ25X300-75 FAQ
This 25 mm bore cylinder features 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 75 mm (usable range 225-300 mm), while needle valves adjust the air cushions at both ends to decelerate high-speed impacts. This specific SKU has no magnet and cannot host sensors; adding a magnet (-S) enables CMSG, DMSG, or EMSG switches.
