About the Airtac MICJ Adjustable Mini Cylinder MICJ25X125-50S
Dial in the exact forward stop on-site with the AirTAC MICJ25X125-50S, a double-acting round-body mini cylinder featuring a 50 mm extend-stroke adjuster. An external stop screw lets you trim the usable extend from 125 mm down to 75 mm without swapping hardware, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. The stainless-steel barrel and Ø10 mm piston rod resist mild corrosion and washdown environments.
Built to the ISO 6432 mini-cylinder mounting interface, this Ø25 bore drops into standard brackets and delivers 245.3 N of push force at 0.5 MPa (206.1 N pull). With a 2:1 safety margin, it provides a safe vertical lift of about 12.5 kg. The -S suffix means a piston magnet is installed, ready for CMSG, DMSG or EMSG position switches. Air connects via a 1/8" port.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X125-50S Is Used
Package Diverter Stop
Tunes the extend stop up to 50 mm to catch varying carton sizes on a conveyor, using the 245.3 N push force to halt 12 kg boxes smoothly.
Film Roll Tensioner
Adjusts the forward reach precisely for different wrap diameters while the dual air cushions absorb the high-speed impact of the rod reaching the new end position.
Light Press Assembly
Delivers a repeatable 245.3 N press stroke for seating small bearings, with the extend screw allowing quick depth changes without swapping the cylinder.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X125-50S the Right Cylinder?
When sizing this bore, step down to a Ø20 model for roughly 157 N push at 0.5 MPa, or step up to a Ø32 for 402 N if this 245.3 N unit is undersized. The 50 mm extend adjuster plus dual air cushions shine in fast set-position moves where you need to tune the forward impact without re-engineering the cell. Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot block is not offered on this adjustable variant).
Remember the stop screw sets the end position but is not a mid-stroke lock. The cylinder will drift and the cushion only decelerates near the stroke end, so fit an external rod lock or pilot check valve if you must hold a load on air loss.
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 MICJ25X125-50S FAQ
This double-acting cylinder uses a 1/8" air port. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 50 mm (usable range 75-125 mm), but it does not lock the piston mid-stroke. Needle valves adjust the air cushion at both ends to decelerate the load before impact. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG sensors.
