About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800H
The SC160X800H is a heavy-duty double-acting pneumatic cylinder from the AirTAC SC tie-rod series, engineered for demanding industrial applications requiring high force and thermal resilience. With a 160 mm bore and an 800 mm stroke, this model generates a substantial push force of 10053 N at 0.5 MPa and 18095 N at the maximum operating pressure of 0.9 MPa, driven by a robust 40 mm diameter piston rod.
This specific variant is equipped with Viton (FKM) seals, designated by the 'H' suffix, extending its operating temperature range from 0 to +150 °C, making it suitable for high-temperature environments like foundries or autoclaves. The cylinder features a 29 mm adjustable air cushion to decelerate the piston smoothly, PT3/4 port threads, and a body length of 239 mm, resulting in a total extended length of 1039 mm. As a genuine AirTAC product, it ensures reliable performance in heavy-duty clamping and pressing tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800H Is Used
High-Temperature Pressing
With Viton seals rated for 0-150°C, this cylinder is ideal for hot pressing, laminating, or vulcanizing machinery where standard seals would fail, providing 18095 N of reliable clamping force.
Heavy-Duty Die Cushioning
Delivers a controlled 10053 N of force at 0.5 MPa for stamping press die cushions. The 29 mm adjustable air cushion provides smooth deceleration for heavy tooling, reducing shock and noise.
Large-Format Material Handling
Used in heavy lifting and transfer stations for pallets or large sheets. The 800 mm stroke and 9425 N pull force at 0.5 MPa effectively manage substantial loads in automated logistics systems.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800H the Right Cylinder?
Select the SC160X800H when your application demands a high-thrust actuator capable of operating in elevated temperatures up to 150°C. If the 18095 N push force at 0.9 MPa exceeds your requirement, consider stepping down to the SC125 bore, which provides 11045 N of push force at the same pressure. For applications needing even greater force, the SC200 bore delivers 28274 N.
For this 800 mm stroke, careful attention to side-loading is critical. The long extension of the 40 mm rod can be susceptible to bending under lateral forces. It is essential to use an external linear guide or ensure the load is perfectly axial to prevent premature rod bearing wear and seal failure. When replacing an existing cylinder, ensure a precise match for all five key points: 160 mm bore, 800 mm stroke, PT port thread, basic mounting (no accessories), and the absence of a magnet.
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 SC160X800H FAQ
At the standard operating pressure of 0.7 MPa, the push force is 14074 N and the pull force is 13195 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No, the SC160X800H is a double-acting cylinder and cannot hold a load safely when air pressure is lost or the valve is centered. The piston will drift. For static load holding, you must integrate an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
