About the Airtac SC80 Standard Cylinder SC80X650SH
The SC80X650SH is a double-acting pneumatic cylinder delivering substantial force in a mid-range 80 mm bore. At 0.5 MPa it pushes with 2513 N, and at the maximum operating pressure of 0.9 MPa the thrust reaches 4523 N, driven by a 25 mm diameter piston rod.
This 650 mm stroke model features a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0–150 °C, making it suitable for high-temperature or aggressive environments. The tie-rod construction keeps the body length compact at 182 mm, with a total extended length of approximately 832 mm.

Where the Airtac SC80 Standard Cylinder SC80X650SH Is Used
High-Temperature Automation
Viton seals allow this cylinder to operate reliably in ovens, autoclaves, and foundry equipment up to 150 °C, where standard seals would degrade.
Heavy Part Transfer
With 2513 N of force at standard line pressure, it efficiently shuttles heavy castings or fabricated metal parts between machining stations.
Sensor-Controlled Pressing
The built-in magnet enables precise mid-stroke or end-stroke sensing, ideal for press-fit operations requiring confirmation of full extension.
Is the Airtac SC80 Standard Cylinder SC80X650SH the Right Cylinder?
For applications needing slightly less force, the 63 mm bore SC63 series provides 2805 N at 0.9 MPa, while stepping up to the 100 mm bore SC100 series increases push force to 7068 N at 0.9 MPa. With a 650 mm stroke, this cylinder has a significant extended length; ensure the 25 mm rod is adequately supported against side loads. For high-cycle or off-axis loads, consider pairing it with an external linear guide to prevent rod bearing wear and bending.
To replace an existing unit, match five key points: 80 mm bore, 650 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal specification for high-temperature operation. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X650SH FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X650SH is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke. For load holding, an external rod lock or pilot-operated check valve is required.
