About the Airtac SC80 Standard Cylinder SC80X350H
The SC80X350H is a double-acting pneumatic cylinder with an 80 mm bore and 350 mm stroke, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150°C. Its 25 mm diameter piston rod and PT3/8 port deliver a push force of 2513 N at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa.
With a body length of 182 mm and a 28 mm adjustable air cushion, this tie-rod cylinder decelerates the piston smoothly at stroke end. The 350 mm stroke is well within the 1500 mm maximum standard stroke for the 80 mm bore, making it a standard, readily available configuration for industrial automation tasks requiring heat-resistant actuation.

Where the Airtac SC80 Standard Cylinder SC80X350H Is Used
Foundry & Heat Treatment
Viton seals enable the SC80X350H to actuate clamps, gates, or pushers inside furnaces and autoclaves where ambient temperatures up to 150°C would degrade standard seals.
Hot Molding Presses
Delivers 2513 N at 0.5 MPa for ejector or core-pull functions in plastic injection and rubber compression molds, maintaining seal integrity under sustained heat soak.
Sterilization Equipment
Withstands aggressive cleaning and steam sterilization cycles in pharmaceutical autoclaves, providing reliable linear motion for door locks and material transfer mechanisms.
Is the Airtac SC80 Standard Cylinder SC80X350H the Right Cylinder?
Choose the SC80X350H when your application demands a force of roughly 2500 N at standard line pressure and the ambient temperature exceeds 70°C. If you need less force, stepping down to the 63 mm bore provides 1559 N at 0.5 MPa; for higher force, the 100 mm bore delivers 3927 N at the same pressure. For this 350 mm stroke, ensure the rod is not subjected to significant side loading—if lateral forces are present, install an external linear guide or consider a guided cylinder to prevent rod bending and premature bearing wear.
This model is a direct replacement only for another AirTAC SC80 cylinder with identical specifications: 80 mm bore, 350 mm stroke, PT3/8 ports, basic mounting, and high-temperature Viton seals. The -H suffix is critical for high-temperature compatibility; a standard TPU seal cylinder will fail prematurely in this operating range.
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 SC80X350H FAQ
At 0.7 MPa operating pressure, the push force is 3518 N and the pull force on the return stroke is 2268 N. The maximum force at 0.9 MPa is 4523 N push.
Yes. The -H suffix designates Viton (FKM) seals rated for 0 to +150°C, unlike the standard TPU seal which is limited to -20 to +70°C. It is a direct dimensional direct for an SC80X350 with PT ports, but you must match the seal material for the operating temperature.
