About the Airtac SC125-160 Standard Cylinder SC160X150H
The SC160X150H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial 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 160 mm bore and a 150 mm stroke, this model features a 40 mm diameter piston rod and an M36x2 rod thread for robust mechanical connections.
This variant is equipped with Viton (FKM) seals, designated by the 'H' suffix, extending the operating temperature range to 0-150°C, making it suitable for high-temperature or chemically aggressive environments. The cylinder body has a length of 239 mm and provides an adjustable air cushion of 29 mm at each end to decelerate the piston smoothly, reducing impact noise and vibration.

Where the Airtac SC125-160 Standard Cylinder SC160X150H Is Used
High-Temperature Foundry Actuation
The Viton seals allow this SC160X150H cylinder to operate reliably in foundry and metalworking environments with ambient temperatures up to 150°C, controlling gates, clamps, or ejectors near furnaces.
Heavy-Duty Press Mechanisms
Generating over 18,000 N of force at 0.9 MPa, this cylinder is ideal for compacting, pressing, and stamping operations in recycling or wood processing machinery where a 150 mm stroke is sufficient.
Chemical Process Valve Actuation
With FKM seals resistant to aggressive chemicals and high heat, this actuator is a dependable choice for automating large quarter-turn valves or linear gate valves in chemical plants and refineries.
Is the Airtac SC125-160 Standard Cylinder SC160X150H the Right Cylinder?
Select the SC160X150H for applications requiring high thrust in hot conditions. If the force requirement is lower, consider stepping down to the SC125 bore (6136 N push at 0.5 MPa) to reduce air consumption and physical size. For even higher force, the SC200 bore provides 15708 N at the same pressure. The 40 mm rod is robust, but for any stroke of 300 mm or more, always evaluate side loads; an external guide or a guided cylinder is necessary to protect the rod bearing from bending moments.
When replacing an existing cylinder, ensure a 5-point match: 160 mm bore, 150 mm stroke, PT port thread, basic mounting (no bracket), and the absence of a magnet. The 'H' suffix specifies Viton seals, which must be matched if the application involves elevated temperatures.
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 SC125-160 Standard Cylinder SC160X150H FAQ
The theoretical push force at 0.5 MPa 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. The maximum theoretical force at 1.0 MPa is 2050 kgf.
No. The SC series is a standard double-acting cylinder and does not have a mechanical lock. If air pressure is exhausted or the directional valve is centered, the piston rod can drift or the load can drop. You must add a pilot-operated check valve or an external rod brake for static load holding.
