About the Airtac SC80 Standard Cylinder SC80X63H
The SC80X63H is an 80 mm bore, 63 mm stroke double-acting tie-rod cylinder fitted with high-temperature Viton (FKM) seals, extending the operating range to 0–150 °C. With a 25 mm piston rod and PT3/8 ports, it delivers 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a strong candidate for hot-environment clamping and pressing tasks.
Its 63 mm stroke falls well within the 1500 mm maximum standard stroke for the 80 bore, keeping the assembly compact with a body length of just 182 mm. The adjustable air cushion (28 mm) decelerates the piston smoothly at end-of-stroke, protecting tooling without locking the load—external holding is required if position must be maintained without pressure.

Where the Airtac SC80 Standard Cylinder SC80X63H Is Used
High-Temperature Clamping
Viton seals allow continuous operation up to 150°C, making the SC80X63H ideal for clamping fixtures inside curing ovens, autoclaves, or near heat-sealing bars.
Hot Press Actuation
Delivers 4523 N at 0.9 MPa for short-stroke pressing in laminating or vulcanizing presses where standard seals would degrade, ensuring reliable cycle life.
Foundry Gate & Diverter
With 2513 N at 0.5 MPa and a 63 mm stroke, it powers small gates or diverters on shakeout conveyors and sand-handling lines, resisting radiant heat from nearby castings.
Is the Airtac SC80 Standard Cylinder SC80X63H the Right Cylinder?
Choose the SC80 bore when the SC63’s 1559 N push at 0.5 MPa is marginal; stepping up to 80 mm nearly doubles the force. For strokes above 300 mm on this 25 mm rod, consider an external guide or a guided cylinder to protect the rod bearing from side loads. A drop-in replacement must match bore (80 mm), stroke (63 mm), PT3/8 port thread, basic mount, and the Viton seal suffix—this is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC80 tie-rod units.

- ✓ 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 SC80X63H FAQ
At 0.7 MPa supply pressure the SC80 bore generates 3518 N of push force. The pull force on the retract stroke is 2268 N at 0.5 MPa, reflecting the area lost to the 25 mm rod.
No. The SC80X63H is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve centres. The adjustable air cushion only decelerates the piston at stroke end; it is not a locking device. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
