Airtac MICJ Adjustable Mini Cylinder MICJ25X250-30
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X250-30 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 250mm 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 MICJ25X250-30
Trim the forward stop by up to 30 mm on site without swapping hardware using this AirTAC MICJ25X250-30 round-body mini cylinder. The external screw adjusts the extend end position (usable range 220-250 mm), while a needle-set variable air cushion at both ends soaks up high-speed shock. Retract remains at the full 250 mm stroke.
Built with a stainless-steel barrel and Ø10 mm piston rod for mild washdown resistance, it conforms to the ISO 6432 mounting interface for standard mini brackets. Delivering 245.3 N of push force at 0.5 MPa, it yields a safe working load of about 147 N, moving roughly 12.5 kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors; the 1/8" port feeds the double-acting chambers.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-30 Is Used
Adjustable Cut-off Gate
Sets a precise 220-250 mm forward stroke to position a diverter gate, using the 30 mm external screw to fine-tune the stop while the dual air cushions absorb the impact of fast 245 N moves.
Product Transfer Pusher
Pushs lightweight cartons between belts; the needle-set cushion decelerates the 250 mm extend before contact, and the stainless build resists humid washdown environments.
Vertical Drop Placer
Lowers a 12 kg component safely using a 2:1 force margin, relying on the adjustable forward stop to set the exact release height without re-mounting the cylinder.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-30 the Right Cylinder?
When sizing this 25 mm bore against adjacent models, stepping down to the Ø20 MICJ drops the 0.5 MPa push force to 157 N, whereas moving up to the Ø32 MICJ raises it to 402 N. Choose this Ø25 variant when you need approximately 245 N of thrust combined with on-the-fly extend tuning to dial in a precise 220-250 mm forward position before the dual air cushions decelerate the load.
Because this is a non-magnet SKU, position sensing via CMSG/DMSG/EMSG switches is not possible without the -S variant. Mount using LB foot, FA flange, or TC trunnion (SDB pivot-block is not offered on this adjustable type). The stop screw and cushions only manage end-of-stroke impact; they do not hold the load on air loss, so add an external rod lock or pilot check valve for vertical safety.
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 MICJ25X250-30 FAQ
This double-acting cylinder delivers 245.3 N push and 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. Its theoretical maximum force is 50 kgf at 1.0 MPa, and it uses a 1/8" air port.
An external screw shortens the extend stroke by up to 30 mm (retract stays full), and a needle-set variable air cushion at both ends decelerates the piston near the ends to soak up high-speed shock. The stop screw is not a mid-stroke lock, and the cylinder will drift on air loss—use an external rod lock to hold a suspended load. This non-S SKU also lacks a magnet for sensors.
