About the Airtac SC80 Standard Cylinder SC80X500H
The SC80X500H is an 80 mm bore, 500 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-fitted with Viton (FKM) seals for reliable operation in high-temperature environments up to 150 °C. With a 25 mm piston rod and PT3/8 ports, it generates a substantial push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa.
Its 500 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a standard catalog item. The body length A is 182 mm, giving a total extended length of approximately 682 mm. An adjustable pneumatic cushion at each end decelerates the piston over a 28 mm cushion length, reducing end-of-stroke impact without any mechanical locking function.

Where the Airtac SC80 Standard Cylinder SC80X500H Is Used
High-Temperature Actuation
Viton seals allow this cylinder to operate continuously in ambient temperatures from 0 to 150 °C, making it suitable for autoclave doors, drying ovens, and foundry equipment.
Heavy Part Clamping
With 4523 N of force at 0.9 MPa, the SC80X500H provides robust clamping for CNC machining fixtures and welding jigs on large structural components.
Material Rejection Gates
The 500 mm stroke and high force output drive diverter gates on heat-resistant conveyor lines, reliably sorting hot materials in glass or metal processing plants.
Is the Airtac SC80 Standard Cylinder SC80X500H the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N push at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the SC63 bore delivers 1559 N at the same pressure. At a 500 mm stroke, ensure the rod is protected from side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear. When replacing an existing unit, match five key points: 80 mm bore, 500 mm stroke, PT port thread, basic mounting (no bracket), and confirm the seal material is Viton 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 SC80 Standard Cylinder SC80X500H FAQ
At the standard 0.5 MPa operating pressure, the cylinder delivers 2513 N pushing force and 2268 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No. The SC80X500H is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of its stroke. For load holding, you must add an external rod lock or a pilot-operated check valve.
