About the Airtac MICJ Adjustable Mini Cylinder MICJ25X100-50S
Dial in exact forward stops on-site with the AirTAC MICJ25X100-50S, a double-acting round-body stainless steel mini cylinder. An external screw trims the extend stroke by up to 50 mm, giving you a usable forward range of 50 to 100 mm, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. The stainless barrel and piston rod resist mild corrosion and washdown environments. Built to the ISO 6432 mounting interface, it drops into standard mini brackets and accepts CMSG, DMSG, or EMSG switches via the integrated -S piston magnet.
Delivering 245.3 N of push force at 0.5 MPa, this bore handles meaningful workloads. The computed safe working load sits around 147 N, translating to a vertical lift of roughly 12.5 kg with a 2:1 safety margin. It operates at speeds of 30-800 mm/s, uses a 1/8" port, and features an M10x1.25 male rod thread. The external stop sets the end position but does not lock mid-stroke; for load holding on air loss, install an external rod lock or pilot check valve.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X100-50S Is Used
Adjustable Clamping Press
Clamp parts securely using the 245.3 N push force, tuning the 50 mm extend stop to accommodate varying material thicknesses without changing tooling.
High-Speed Divert Gate
Rapidly route boxes on a conveyor at up to 800 mm/s, relying on the dual adjustable air cushions to absorb shock at the extend and retract ends.
Variable Stroke Sealing Head
Apply consistent downward pressure for carton sealing, using the external screw to shorten the forward stroke for different package heights.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X100-50S the Right Cylinder?
When sizing this 25 mm bore, compare it directly to adjacent options. Stepping down to the 20 mm bore drops your 0.5 MPa push force to 157 N, whereas stepping up to the 32 mm bore raises it to 402.2 N. Choose this model when you need the 245.3 N thrust combined with on-the-fly extend adjustments and high-speed cushioning. The 50 mm adjuster window is ideal for tuning fast set-position moves without machining spacers.
Mounting options include LB foot, FA flange, and TC trunnion, plus CA, U, R, or CM back covers. Note that the SDB pivot block is not available on this adjustable-stroke variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for position detection. Remember that the air cushion only decelerates near the stroke end—it is not a mid-stroke brake.
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 MICJ25X100-50S FAQ
This double-acting cylinder delivers 245.3 N push and 206.1 N pull at 0.5 MPa, and 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a 1/8" air port and a 10 mm piston rod with an M10x1.25 male thread.
The external stop screw shortens the extend stroke by up to 50 mm on-site, while the needle-set adjustable air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The -S suffix indicates a built-in piston magnet, allowing the use of CMSG, DMSG, or EMSG sensors for position detection.
