About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X700H
The AirTAC SC160X700H is a double-acting tie-rod cylinder engineered for high-temperature environments, specified with high-performance Viton (FKM) seals that extend the operating range from 0 to +150 °C. With a 160 mm bore and 700 mm stroke, this unit generates a substantial 10053 N of push force at 0.5 MPa, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa, driven by a robust 40 mm diameter piston rod.
This model is built on the SC platform, featuring an adjustable pneumatic cushion (29 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The total extended body length is approximately 939 mm. PT (Rc) port threads in size 3/4 inch provide the standard air connection, and the cylinder is compatible with the full range of F-SC160 mounting accessories for flexible integration.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X700H Is Used
High-Temperature Clamping
Operates reliably in autoclave lid clamping or hot press fixtures where ambient temperatures reach up to 150 °C, thanks to the Viton seal package.
Foundry & Glass Machinery
Provides the 18095 N of push force needed to actuate heavy molds or gates in foundry and glass forming equipment, resisting radiant heat without seal failure.
Heavy Industrial Actuation
Delivers consistent, high-force linear motion for large valves, dampers, or material handling pushers in processing plants with elevated ambient temperatures.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X700H the Right Cylinder?
Select the SC160X700H when your application demands high force in a heated setting, such as near ovens or autoclaves. The Viton seal package is the defining feature here, ensuring reliable operation where standard TPU seals would degrade. If your force requirement is lower at a given pressure, consider stepping down to the 125 mm bore (6136 N at 0.5 MPa); for even greater force, the 200 mm bore model provides 15708 N at the same 0.5 MPa pressure.
For this 700 mm stroke, carefully evaluate side-loading conditions. An unsupported 40 mm rod at full extension is vulnerable to bending and uneven bearing wear under lateral forces. It is critical to use an external guide system or ensure the load is perfectly axial. For a direct replacement, match the 160 mm bore, 700 mm stroke, PT port thread, and Viton seal material. The basic configuration has no built-in magnet, so if you require position sensing, an external switch mounting solution is necessary.
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 SC160X700H FAQ
At the maximum operating pressure of 0.9 MPa, the push force is 18095 N. At the standard 0.7 MPa, it produces 14074 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, making it dimensionally non-interchangeable. It is a direct replacement only for another AirTAC SC160 tie-rod cylinder with matching bore, stroke, and port thread.
