About the Airtac SC80 Standard Cylinder SC80X80H
The SC80X80H is an AirTAC SC series double-acting tie-rod cylinder with an 80 mm bore and 80 mm stroke, fitted with high-temperature Viton (FKM) seals. It delivers a push force of 2513 N at 0.5 MPa and reaches 4523 N at the maximum operating pressure of 0.9 MPa, making it a strong mid-range actuator for hot environments.
With Viton seals, the operating temperature range shifts to 0 to +150 °C, suitable for autoclaves, drying ovens, or foundry equipment where standard TPU seals would degrade. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end ensure reliable deceleration. The total extended body length is approximately 262 mm (body length A of 182 mm plus the 80 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X80H Is Used
High-Temperature Process Actuation
Viton seals allow the SC80X80H to operate continuously at up to 150 °C, making it ideal for controlling dampers, valves, or clamps in autoclaves, steam processes, and industrial drying lines.
Hot Press & Molding Ejection
Delivers a powerful 4523 N push at 0.9 MPa for ejecting parts from heated molds in rubber or composite presses, where standard seal materials would fail prematurely.
Laboratory & Test Chamber Actuation
The 80 mm stroke and clean double-acting operation suit environmental test chamber door lifts or specimen positioning inside temperature-controlled enclosures.
Is the Airtac SC80 Standard Cylinder SC80X80H the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force. If you require less force, stepping down to the SC63 bore provides 1559 N at 0.5 MPa, which may allow for a smaller, lighter actuator. For higher force, the SC100 bore offers 3927 N at the same pressure.
For a direct replacement, match these five points: 80 mm bore, 80 mm stroke, PT port thread, basic mount (no bracket), and no magnet. This model uses Viton seals; ensure the replacement also has high-temperature seals if the operating environment exceeds 70 °C. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80 Standard Cylinder SC80X80H FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X80H is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop under load. For load-holding safety, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
