About the Airtac MICJ Adjustable Mini Cylinder MICJ25X50-50
Dial in the exact forward stop on site with the AirTAC MICJ25X50-50, a stainless-steel round-body mini cylinder featuring a 50 mm adjustable extend stroke. An external stop screw trims the extend end position down to zero, while the retract stroke remains full. Built with a 10 mm piston rod and a 1/8" port, it delivers 245.3 N of push force at 0.5 MPa.
This double-acting unit pairs its on-site stroke adjustment with a variable air cushion at both ends to soak up high-speed shock. The stainless barrel and rod resist mild corrosion and washdown environments. It uses the ISO 6432 mounting interface for standard mini brackets. With a 2:1 safety margin, it provides a safe vertical lift of about 12.5 kg. Note this SKU lacks a magnet and cannot take sensors; the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X50-50 Is Used
Sorting Diverter
Pushes light packages at high speed onto a secondary line, using the 50 mm extend adjustment to dial in the exact push distance and the air cushion to prevent end-of-stroke slamming.
Carton Flap Folder
Folds corrugated flaps prior to sealing. The 245 N push force handles stiff cardboard, while the adjustable forward stop ensures precise folding without crushing the carton.
Light Press Fit
Seats small bearings or pins. The 12.5 kg safe vertical lift provides steady force, and the needle-set cushion decelerates the tool head to avoid damaging delicate components.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X50-50 the Right Cylinder?
This 25 mm bore provides a safe working load of roughly 147 N (60% of the 0.5 MPa push force). If you need less force, the smaller 20 mm bore offers 157 N push, and if you need more, the 32 mm bore provides 402 N. The adjustable stop screw and dual cushions shine in fast set-position moves where you must tune the impact and end point without swapping cylinders. For mounting, use LB foot, FA flange, or TC trunnion (SDB is not available). Remember the stop screw sets the end position but is not a mid-stroke lock; if air is lost, the piston drifts. Use an external rod lock or pilot check valve to hold a load.
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 MICJ25X50-50 FAQ
This 25 mm bore cylinder uses a 1/8" port. 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 screw shortens the extend stroke by up to 50 mm on site, while needle valves adjust the air cushions at both ends to absorb high-speed shock. The cylinder is double-acting. This SKU has no magnet and cannot take sensors; the -S variant is required for CMSG/DMSG/EMSG switches. The stop screw is not a mid-stroke lock, and the piston will drift if air pressure is lost.
