About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50H
The SC160X50H is a double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 50 mm stroke and a 40 mm diameter piston rod, this model is built for short, powerful linear movements in high-temperature environments.
Equipped with Viton (FKM) seals, the operating temperature range shifts to 0 to +150 °C, making it suitable for autoclaves, foundries, or drying equipment where standard seals would degrade. The body length A is 239 mm, and the port size is PT3/4, ensuring high flow for rapid cycling.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50H Is Used
High-Temperature Clamping
Viton seals allow this cylinder to operate reliably in 0–150 °C environments, making it ideal for clamping fixtures in autoclaves, vulcanizing presses, or industrial ovens.
Heavy Die Ejection
With 18095 N of force at 0.9 MPa, the SC160X50H provides the short, powerful stroke needed to eject heavy parts from metal stamping or die-casting molds.
Foundry Gate Actuation
The robust tie-rod construction and heat-resistant seals handle the radiant heat and dust of foundry environments, reliably actuating material flow gates or diverter chutes.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50H the Right Cylinder?
This 160 mm bore cylinder is a high-force actuator. If your application requires even greater force, the SC200 series offers a push force of 15708 N at 0.5 MPa. For lower force requirements, the SC125 provides 6136 N at the same pressure. Always ensure the mounting and rod end are rigidly aligned to prevent side loading on the 40 mm rod.
For a direct replacement, match five key specifications: the 160 mm bore, 50 mm stroke, PT3/4 port thread, basic mounting configuration, and the absence of a built-in magnet. The Viton seal variant is critical for high-temperature 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 SC160X50H FAQ
At the maximum operating pressure of 0.9 MPa, the push force is 18095 N. At a typical factory pressure of 0.5 MPa, the push force is 10053 N, and the pull force is 9425 N.
No. The SC160X50H is a standard double-acting cylinder and will drift or drop if air pressure is exhausted. For load holding without live pressure, you must add an external pilot-operated check valve or a mechanical rod lock.
