About the Airtac SC80 Standard Cylinder SC80X75H
The SC80X75H is an 80 mm bore, 75 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with high-temperature Viton (FKM) seals. This seal upgrade shifts the operating temperature range to 0 to +150 °C, making it suitable for hot environments, foundries, or processes involving aggressive media where standard TPU would degrade.
With a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end, this cylinder delivers smooth deceleration even under high cycle rates. At the standard 0.5 MPa operating pressure, it generates 2513 N of push force and 2268 N of pull force, rising to 4523 N at 0.9 MPa. The body length A is 182 mm, giving a compact footprint for its force class.

Where the Airtac SC80 Standard Cylinder SC80X75H Is Used
Foundry & Heat Treatment
Operates reliably in ambient temperatures up to 150°C, ideal for clamping hot parts, opening furnace doors, or actuating mechanisms near heat sources.
Chemical Processing
Viton seals resist aggressive chemicals and solvents, making this cylinder suitable for dosing systems, valve actuation, and mixing equipment in harsh fluid environments.
High-Cycle Automation
Combines 2513 N of push force with a 75 mm stroke for fast, repetitive tasks like sorting, ejecting, or pressing in automated assembly lines.
Is the Airtac SC80 Standard Cylinder SC80X75H the Right Cylinder?
Choose the SC80 bore when your application needs roughly 2.5 kN of force at 0.5 MPa. If you require more force, step up to the SC100 bore which provides 3927 N at the same pressure; for a lighter, more compact solution, the SC63 bore delivers 1559 N. For strokes of 75 mm, side-loading is typically minimal, but always ensure the load is guided externally if off-axis forces are present to protect the rod bearing and seals. When replacing this cylinder, match five points: 80 mm bore, 75 mm stroke, PT port thread, basic mount (no accessories), and no magnet. The Viton seal code 'H' is critical 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 SC80X75H FAQ
At 0.7 MPa (7 bar) operating pressure, this 80mm bore cylinder produces 3518 N of push force and 2268 N of pull force. The maximum force at 0.9 MPa is 4523 N push.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and mounting configuration.
