About the Airtac MICJ Adjustable Mini Cylinder MICJ25X80-50
Trim the forward stop by up to 50 mm on site without swapping hardware using this AirTAC MICJ25X80-50 stainless round-body mini cylinder. The external screw shortens the extend end position (usable extend 30-80 mm) while the retract stroke remains full, and an adjustable air cushion at both ends soaks up high-speed shock. The 1/8" port and M10x1.25 male rod thread feed a 25 mm bore that delivers 245.3 N of push force at 0.5 MPa.
Built with a stainless-steel barrel and piston rod for mild washdown resistance, this double-acting unit conforms to the ISO 6432 mounting interface for standard mini brackets. It provides a safe working load of roughly 147 N, moving about 12.5 kg vertically with a 2:1 margin. Note this SKU lacks a magnet and cannot take sensors; the -S variant is required for CMSG, DMSG or EMSG switches.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X80-50 Is Used
Adjustable Clamping
Dial in the exact 30-80 mm extend reach to clamp irregular parts securely using 245.3 N of force without retooling fixtures.
Gate Diversion
Absorb the impact of fast-acting conveyor sorting arms using the dual adjustable air cushions to prevent end-cap wear.
Product Pushing
Push lightweight cartons off a line at speed, relying on the 147 N safe working load and fine-tuned forward stop.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X80-50 the Right Cylinder?
When sizing this 245.3 N push class, stepping down to the 20 mm bore drops thrust to 157 N, while moving up to the 32 mm bore increases it to 402 N. Choose this 25 mm model when you need moderate force paired with a fast, settable forward position. The adjustable stop screw and needle-set cushion excel in rapid positioning, but remember the screw only sets the end position—it is not a mid-stroke lock. For load holding on air loss, install an external rod lock or pilot check valve, as the piston will drift. Mount via LB foot, FA flange or TC trunnion (SDB is unavailable), and select the -S version if you need position sensing.
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 MICJ25X80-50 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 screw shortens the extend stroke by up to 50 mm, while a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. The cushion only decelerates and the screw sets the end position; neither acts as a mid-stroke lock, so the piston drifts on air loss. This non-S SKU cannot take sensors.
