About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X10S
The SC125X10S is a compact-stroke double-acting cylinder delivering 6136 N of push force at 0.5 MPa, ideal for short clamping, ejecting, or positioning tasks where space is limited. Its 32 mm diameter piston rod and 28 mm adjustable air cushion ensure reliable deceleration even in high-cycle applications.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for precise end-of-stroke detection. Operating on filtered air from 0.15 to 1.0 MPa, it provides consistent performance in standard temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X10S Is Used
Short-Stroke Clamping
Delivers 6136 N at 0.5 MPa for compact fixtures and jigs, securely holding parts during machining or assembly with a minimal footprint.
Automated Ejection
The 10 mm stroke and built-in magnet make it perfect for high-speed part ejection, with sensors confirming full rod retraction on every cycle.
Diverter Gate Actuation
Operates small diverter gates on conveyor lines, using the magnet for gate position feedback to the central PLC.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X10S the Right Cylinder?
For applications requiring a shorter stroke with integrated position sensing, the SC125X10S is a direct fit. If your load demands higher force, consider stepping up to the SC160 bore, which provides 10053 N of push force at the same 0.5 MPa. When replacing an existing cylinder, ensure you match the 125 mm bore, 10 mm stroke, PT port thread, and the -S magnet option, as the SC series has a shorter body length than ISO 15552 profiles and is not dimensionally interchangeable with them.
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 SC125X10S FAQ
At 0.7 MPa (7 bar) operating pressure, the SC125X10S generates a theoretical push force of 8590 N. The maximum push force at the 0.9 MPa limit is 11045 N.
Yes. The -S suffix indicates a built-in magnetic ring on the piston, making it compatible with AirTAC CMSG, DMSG, and EMSG series sensors that clamp onto the tie-rod barrel for non-contact position sensing.
