About the Airtac SC80 Standard Cylinder SC80X980H
The AirTAC SC80X980H is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the 0.9 MPa maximum operating pressure. Its 25 mm diameter piston rod and 28 mm adjustable air cushion are engineered for reliable deceleration of substantial loads at the end of a 980 mm stroke.
This model is configured with the 'H' suffix, specifying high-temperature Viton (FKM) seals that extend the operating temperature range from 0 to +150 °C, making it suitable for autoclaves, foundries, and other hot-environment automation. The tie-rod construction and PT3/8 port ensure straightforward integration into existing pneumatic circuits.

Where the Airtac SC80 Standard Cylinder SC80X980H Is Used
High-Temperature Process Automation
With Viton seals rated for 0 to +150 °C, this cylinder is ideal for actuating dampers, valves, or clamps inside autoclaves, curing ovens, and heat-treatment lines where standard seals would degrade.
Long-Reach Material Handling
The 980 mm stroke combined with a 2513 N push force at 0.5 MPa enables long-distance pushing or lifting of heavy totes, panels, or engine blocks on transfer stations and lift-assist devices.
Hot Press & Laminating Equipment
Delivers up to 4523 N of force at 0.9 MPa for pressing, bonding, or laminating operations in machinery where both high force and high ambient temperatures are present.
Is the Airtac SC80 Standard Cylinder SC80X980H the Right Cylinder?
For applications requiring less force, stepping down to a 63 mm bore SC63 series reduces push force to 1559 N at 0.5 MPa. If a higher force is needed, the 100 mm bore SC100 series provides 3927 N at the same pressure. Always match the bore, 980 mm stroke, PT3/8 port thread, and the specific Viton seal material when replacing this cylinder.
Given the 980 mm stroke, careful attention to side-load management is critical. The long, unsupported 25 mm piston rod is susceptible to bending under lateral forces. For reliable operation, use an external linear guide or rod support to ensure the load is purely axial, preventing premature rod bearing wear and seal failure.
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 SC80X980H FAQ
The theoretical force for an 80 mm bore at 0.5 MPa is 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. These values are based on filtered air and standard conditions.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than a standard ISO 15552 profile cylinder, so the mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with the same 980 mm stroke, PT3/8 port, and Viton seal specification.
