About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X25S
The SC125X25S is a double-acting pneumatic cylinder delivering 6136 N push force at 0.5 MPa (11045 N at 0.9 MPa) from its 125 mm bore. With a short 25 mm stroke and a 32 mm diameter piston rod, it suits compact clamping, pressing, and ejecting tasks where high force is needed in a minimal linear travel.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the tie-rod barrel for reliable end-of-stroke detection. The adjustable air cushion (28 mm length) decelerates the piston smoothly, and the PT1/2 port threads connect easily to standard pneumatic fittings.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X25S Is Used
High-Force Clamping
Short 25 mm stroke and 6136 N push at 0.5 MPa make it ideal for pneumatic clamps and press fixtures requiring compact, powerful actuation.
Part Ejection
Delivers a quick, forceful punch to eject stamped or molded parts from dies, with magnetic piston sensing to confirm each cycle.
Diverter Gates
Actuates sorting gates and diverters on conveyors where a short, high-force stroke directs product flow, with sensor feedback for automation control.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X25S the Right Cylinder?
For applications needing slightly less force, the SC100 bore provides 3927 N push at 0.5 MPa. If the 25 mm stroke is too short, standard strokes up to 1500 mm are available in this 125 mm bore. When replacing an existing cylinder, match five points: 125 mm bore, 25 mm stroke, PT1/2 ports, the -S magnet option for sensor compatibility, and the basic (no bracket) mounting configuration.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac AIRTAC SC125-160 Standard Cylinder SC125X25S FAQ
At 0.5 MPa air pressure, the 125 mm bore generates 6136 N push and 5734 N pull. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X25S indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the barrel's tie-rod slots for contactless position sensing.
