About the Airtac SC80 Standard Cylinder SC80X650H
The SC80X650H is a double-acting pneumatic cylinder with an 80 mm bore and a 650 mm stroke, fitted with high-temperature Viton (FKM) seals for reliable operation in ambient temperatures from 0 to +150 °C. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration at the end of travel, making it suitable for demanding thermal environments.
At a standard operating pressure of 0.5 MPa, this cylinder delivers a push force of 2513 N and a pull force of 2268 N. The maximum theoretical push force at 0.9 MPa reaches 4523 N. With a body length A of 182 mm and a total extended length of approximately 832 mm, it is a robust tie-rod design that is shorter than an equivalent ISO 15552 profile cylinder.

Where the Airtac SC80 Standard Cylinder SC80X650H Is Used
High-Temperature Automation
With Viton seals rated for 0-150°C, this cylinder is ideal for actuators near ovens, autoclaves, or foundry equipment where standard seals would degrade.
Heavy Part Clamping
Delivering over 2500 N of force at 0.5 MPa, it provides powerful, controlled clamping for welding fixtures or machining centers in hot manufacturing cells.
Material Pusher in Hot Zones
The 650 mm stroke and high-temperature rating make it a reliable choice for diverting or pushing products on conveyor lines running through curing or drying tunnels.
Is the Airtac SC80 Standard Cylinder SC80X650H the Right Cylinder?
For applications requiring less force, consider stepping down to a 63 mm bore, which provides 1559 N of push force at 0.5 MPa. If higher force is needed, the 100 mm bore model offers 3927 N at the same pressure. This 650 mm stroke is within the standard range for the 80 mm bore, which supports strokes up to 1500 mm.
For a stroke of this length, avoid side loading the rod directly; use an external linear guide or a guided cylinder to prevent bending stress on the rod bearing. When replacing this cylinder, match five key points: 80 mm bore, 650 mm stroke, PT port thread, basic (no bracket) mounting, and the high-temperature Viton seal material.
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 SC80X650H FAQ
At 0.7 MPa operating pressure, the SC80X650H produces a theoretical push force of 3518 N. The maximum push force at the 0.9 MPa operating limit is 4523 N.
No. As a standard double-acting cylinder, the SC80X650H will drift or drop if air pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
