About the Airtac SC80 Standard Cylinder SC80X700H
The AirTAC SC80X700H is a double-acting pneumatic cylinder with an 80 mm bore and 700 mm stroke, built for high-temperature duty up to 150 °C thanks to its Viton (FKM) seals. It generates a theoretical push force of 2513 N at 0.5 MPa and 4523 N at its maximum operating pressure of 0.9 MPa, placing it in a robust force class for medium-to-heavy industrial actuation.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The body length A is 182 mm, giving a total extended length of approximately 882 mm. Its adjustable pneumatic cushion (28 mm length) decelerates the piston at stroke end to reduce impact, but it does not lock or hold the load—external braking is required for position holding without live pressure.

Where the Airtac SC80 Standard Cylinder SC80X700H Is Used
High-Temperature Process Actuation
The Viton seals allow continuous operation up to 150 °C, making this cylinder suitable for autoclave door actuation, drying oven material handling, or foundry knock-out stations where standard seals would degrade.
Long-Stroke Part Transfer
With a 700 mm stroke and 4523 N of push force at 0.9 MPa, it efficiently transfers heavy pallets or engine blocks between conveyor lines, provided the rod is externally guided to prevent bending.
Hot Press Clamping
Delivers consistent clamping force for heated platen presses in composite molding or plywood lamination, where the high-temperature seal ensures reliability through extended thermal cycles.
Is the Airtac SC80 Standard Cylinder SC80X700H the Right Cylinder?
Choose the SC80X700H where an 80 mm bore provides the force headroom needed for a 700 mm stroke at elevated temperatures. If your load requires less force, stepping down to a 63 mm bore (1559 N push at 0.5 MPa) can reduce air consumption; for heavier loads, the 100 mm bore delivers 3927 N at 0.5 MPa. At this 700 mm stroke, side-load management is critical—the unsupported 25 mm rod can bend under lateral force, so always guide the load externally or pair the cylinder with a dedicated guided unit.
For a direct replacement, match five attributes: 80 mm bore, 700 mm stroke, PT3/8 ports, basic (no bracket) mounting, and the high-temperature Viton seal designated by the H suffix. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC80 of the same configuration.
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 SC80X700H FAQ
At 0.7 MPa (7 bar) supply pressure, the theoretical push force is 3518 N. The pull force on the retract stroke at the same pressure is slightly lower due to the rod area, delivering 3175 N. Always apply a safety factor for real-world dynamic loads.
No. The SC80X700H is a standard double-acting cylinder and will drift or drop its load if pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end. To hold a position without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
