About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X170STC
The SC160X170STC is a robust double-acting tie-rod cylinder delivering a push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 170 mm stroke and a 40 mm diameter piston rod, this model is built for heavy linear pushing and pulling tasks where a pivoting mount is essential.
This configuration includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The centre trunnion mount (TC) with the included TCM1 bracket allows the cylinder body to pivot, accommodating angular movement in the application. The standard TPU seals provide reliable operation within a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X170STC Is Used
Heavy-Duty Clamping
Provides high force for securing large workpieces on CNC machining centres or welding fixtures, with the trunnion mount allowing the cylinder to swing clear for loading.
Agricultural Equipment Actuation
Operates chutes, gates, or conveyors on harvesters and spreaders. The pivoting TC mount handles misalignment on rugged terrain, and the magnet confirms gate position.
Water Treatment Valve Control
Powers large butterfly or gate valves in water treatment plants. The 18095 N max force at 0.9 MPa ensures positive valve operation, with sensor feedback for SCADA integration.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X170STC the Right Cylinder?
For applications requiring a pivoting mount, the centre trunnion (TC) is the correct choice, and this model ships with the F-SC160TC bracket. When sizing, if 10053 N of push force at 0.5 MPa is insufficient, stepping up to the 200 mm bore provides 15708 N. If the force is excessive, the 125 mm bore offers 6136 N. To ensure a correct replacement, match the 160 mm bore, 170 mm stroke, PT port thread, TC centre trunnion mounting, and the built-in magnet (-S) sensor compatibility.
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 SC160X170STC FAQ
At the standard 0.5 MPa air pressure, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N.
No. The SC series is a tie-rod cylinder and is shorter in overall length than a comparable ISO 15552 cylinder, so mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC160 tie-rod cylinder with matching bore, stroke, PT ports, TC mount, and magnet.
