About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X260S
The SC125X260S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial push force of 6136 N at 0.5 MPa (up to 11045 N at the 0.9 MPa maximum operating pressure). With a 125 mm bore and 260 mm stroke, this model features a 32 mm piston rod and an adjustable air cushion length of 28 mm to decelerate end-of-stroke impacts smoothly.
This unit includes the built-in magnet suffix 'S', allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for non-contact position feedback. The body length A is 203 mm, making the total extended length approximately 463 mm. It operates on filtered air from 0.15 to 1.0 MPa and uses standard PT port threads and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X260S Is Used
Heavy Press & Clamping
With 11045 N of force at 0.9 MPa, this cylinder suits heavy-duty clamping fixtures and small forming presses where consistent, high-force linear motion is required.
Material Handling Gates
Ideal for actuating diverter gates or heavy stoppers on conveyor lines, using the built-in magnet for end-of-stroke sensing to confirm gate position.
Industrial Automation
A robust actuator for lifting, tilting, or transferring heavy components in automated assembly cells, leveraging the adjustable cushion to protect tooling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X260S the Right Cylinder?
For applications needing slightly less force, the SC100 bore provides 3927 N at 0.5 MPa, while stepping up to the SC160 bore offers 10053 N. This 260 mm stroke is within the 1500 mm maximum standard stroke for the 125 mm bore. The SC125X260S is an ISO 6430 class tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
For a direct replacement, match five points: 125 mm bore, 260 mm stroke, PT port thread, the built-in magnet (-S), and any required mounting accessory. For this stroke length, ensure the rod is guided externally if the load applies significant side force, as the unsupported 32 mm rod can be subject to bending moments.
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 SC125X260S FAQ
At the standard 0.5 MPa operating pressure, the theoretical push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N.
Yes. The 'S' suffix in the model code SC125X260S indicates a built-in magnet is installed on the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor slot for reliable position detection.
