About the Airtac SC80 Standard Cylinder SC80X650CA
The SC80X650CA is an 80 mm bore, 650 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model features a rear single clevis (CA) mount, allowing the cylinder body to pivot during operation, which is ideal for articulated linkages. The adjustable pneumatic cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact. The body length A is 182 mm, resulting in a total extended length of approximately 832 mm.

Where the Airtac SC80 Standard Cylinder SC80X650CA Is Used
Material Handling Pusher
The 650 mm stroke and pivoting clevis mount make this cylinder suitable for pusher arms on conveyor lines, diverting packages or components between lanes with a controlled, linear motion.
Agricultural Implement Actuation
With its robust tie-rod construction and rear pivot, this cylinder operates reliably in dusty conditions to actuate chutes, gates, or linkages on farm machinery like balers and spreaders.
Clamping & Fixturing
The high force output at 0.9 MPa (4523 N) combined with the long stroke provides a powerful clamping action for large weldments or assemblies in heavy manufacturing fixtures.
Is the Airtac SC80 Standard Cylinder SC80X650CA the Right Cylinder?
Selecting the correct cylinder requires matching the force to the load. At 0.5 MPa, the 80 mm bore provides 2513 N push force. If your load requires less force, consider stepping down to the 63 mm bore, which provides 1559 N at the same pressure. For higher force demands, the 100 mm bore offers 3927 N at 0.5 MPa.
For this 650 mm stroke, ensure the load is guided and side forces are minimized. Long, unsupported strokes on a single rod can create a bending moment on the rod bearing, leading to premature seal wear. Use an external guide rail or rod alignment coupler for purely axial loads. When replacing an existing cylinder, match all five critical points: 80 mm bore, 650 mm stroke, PT port thread, rear single clevis (CA) mount, and the absence of a built-in magnet.
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 SC80X650CA FAQ
The theoretical push force is 2513 N at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is slightly lower due to the rod area, delivering 2268 N at 0.5 MPa.
It is not recommended to push a free load over this distance without external guidance. The 25 mm rod can bend under side load or high thrust. Always use an external guide rail or a guided cylinder configuration to protect the rod and seals from premature wear.
