About the Airtac SC80 Standard Cylinder SC80X300H
The SC80X300H is an 80 mm bore double-acting tie-rod cylinder with a 300 mm stroke, factory-fitted with Viton (FKM) seals for reliable operation in high-temperature environments up to 150°C. At 0.5 MPa it delivers 2513 N pushing force, rising to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod with PT3/8 ports.
Its 28 mm adjustable air cushion decelerates the piston smoothly at both ends, protecting end caps during high-speed cycles. The body length A is 182 mm, giving an approximate extended length of 482 mm for this stroke. This genuine AirTAC SC cylinder is a robust choice for hot-process actuation where standard seals would degrade.

Where the Airtac SC80 Standard Cylinder SC80X300H Is Used
High-Temperature Process Actuation
Viton seals allow the SC80X300H to operate continuously at 0-150°C, making it suitable for autoclave doors, drying ovens, and foundry equipment where standard seals would fail.
Hot Material Handling & Sorting
With 2513 N of push force at 0.5 MPa and a 300 mm stroke, it powers diverters and pushers on lines handling hot glass, ceramics, or baked goods, resisting heat soak from nearby processes.
Press & Clamping in Heated Tools
Delivers up to 4523 N at 0.9 MPa for clamping fixtures in heated presses, laminating machines, or thermoforming tools, maintaining seal integrity under sustained thermal load.
Is the Airtac SC80 Standard Cylinder SC80X300H the Right Cylinder?
Choose the SC80 bore when your application needs 2513 N at 0.5 MPa; for lower force step down to the SC63 (1559 N at 0.5 MPa), or up to the SC100 (3927 N at 0.5 MPa) if more thrust is required. At 300 mm stroke, ensure the rod is not subjected to significant side load—an external guide or guided cylinder is recommended to prevent rod bending and premature bearing wear.
For direct replacement, match bore (80 mm), stroke (300 mm), PT port thread, basic mount, and the Viton seal suffix (H). This cylinder is a direct replacement for another AirTAC SC80X300H or an equivalent tie-rod cylinder with the same critical dimensions and port type.
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 SC80X300H FAQ
At 0.5 MPa the push force is 2513 N and pull force is 2268 N. At 0.7 MPa push force reaches 3518 N, and at the maximum operating pressure of 0.9 MPa it produces 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder and is shorter in overall length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. Use it to replace another AirTAC SC80 or a tie-rod cylinder with matching bore, stroke, PT3/8 ports, and basic mounting.
