Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75S 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 MICJ25X300-75S
Trimming the forward stop by up to 75 mm on site, the AirTAC MICJ25X300-75S lets you dial in a 225-300 mm extend position without swapping hardware. This double-acting round-body mini cylinder pairs that external stop screw with a needle-adjustable air cushion at both ends, soaking up high-speed shock at the end of travel.
Built with a stainless-steel barrel and Ø10 mm piston rod, it handles mild washdown and delivers 245.3 N of push force at 0.5 MPa. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the 1/8" port and ISO 6432 mounting interface drop directly into standard mini brackets. For a safe working load, expect around 147 N, which moves about 12.5 kg vertically with a 2:1 margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75S Is Used
Adjustable Cut-off Saw
Dials the 300 mm extend down by 75 mm to set a precise stop for a cutting blade, using the air cushion to absorb the impact of the high-speed thrust move.
Variable Position Diverter
Pushes packages with 245.3 N of force at 0.5 MPa while allowing operators to tweak the extend endpoint on the line without changing the cylinder mounting.
Vertical Lift Gate
Lifts a 12.5 kg gate with a 2:1 safety margin, relying on the needle cushion to soften the end-of-stroke shock during rapid vertical actuation.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-75S the Right Cylinder?
When sizing this 25 mm bore, dropping down to a 20 mm MICJ cuts the 0.5 MPa push force to 157 N, while stepping up to a 32 mm bore raises it to 402 N. Choose this 25 mm model when you need roughly 147 N of safe working force combined with a dial-in forward stop for fast, settable-position moves. The adjustable air cushion handles the deceleration at high speed, but remember the piston drifts on air loss—the stop screw sets the end position, it is not a mid-stroke lock, so add an external rod lock or pilot check valve to hold a suspended load.
Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot-block is not offered on this adjustable variant). Because this SKU includes the -S magnet, you can fit CMSG, DMSG or EMSG sensors directly into the slot.
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 MICJ25X300-75S FAQ
This 25 mm bore cylinder uses a 1/8" air port and a male M10x1.25 rod thread. At 0.5 MPa it provides 245.3 N push and 206.1 N pull; at 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 75 mm on site, giving a usable forward range of 225-300 mm (retract remains full stroke). A needle-set air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
