About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X115SH
The SC125X115SH is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 115 mm stroke, this model is well-suited for medium-travel clamping, pressing, and material handling tasks where high force and heat resistance are required.
This variant is equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0 to +150 °C. The 32 mm diameter piston rod features an M27x2 thread, and the 28 mm adjustable air cushion decelerates the load smoothly at the end of the stroke.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X115SH Is Used
High-Temperature Pressing
Viton seals enable reliable operation in autoclaves and heated platen presses up to 150 °C, where standard seals would degrade.
Foundry & Forge Actuation
Delivers over 11,000 N of force at 0.9 MPa for moving heavy molds, gates, or manipulators in hot, aggressive environments.
Heavy Part Sorting
The built-in magnet allows easy addition of reed switches for end-of-stroke sensing, ideal for diverting large castings on heat-resistant conveyors.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X115SH the Right Cylinder?
For applications needing less force, stepping down to a 100 mm bore reduces push force to 3927 N at 0.5 MPa. If your 115 mm stroke carries significant side load, consider an external guide or a guided cylinder, as the unsupported 32 mm rod can be subject to bending moments. This ISO 6430 class cylinder is a direct replacement for another AirTAC SC125 tie-rod unit matching the 115 mm stroke, PT port, built-in magnet, and Viton seal configuration.
Quick checklist

- ✓ 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 SC125X115SH FAQ
At 0.5 MPa, the cylinder provides 6136 N pushing and 5734 N pulling. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. It is dimensionally shorter and not interchangeable with ISO 15552 cylinders. For the 125 mm bore, it conforms to the ISO 6430 class for tie-rod cylinders. Use AirTAC F-SC125 series mounting accessories for a guaranteed fit.
