About the Airtac SC80 Standard Cylinder SC80X50CA
The SC80X50CA is an 80 mm bore double-acting pneumatic cylinder with a short 50 mm stroke, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide reliable deceleration for compact linear moves.
This model features a rear single clevis (CA) mount, part F-SC80CA, allowing the cylinder body to pivot during operation to accommodate angular misalignment. The standard PT1/8 port and TPU seals with a -20 to +70 °C temperature range make it a robust choice for general industrial clamping and positioning tasks.

Where the Airtac SC80 Standard Cylinder SC80X50CA Is Used
Clamping Fixtures
The 2513 N force at 0.5 MPa combined with the short 50 mm stroke is ideal for securely clamping parts in machining or welding fixtures where a pivoting cylinder body is needed for clearance during loading.
Part Ejection
Provides a powerful, compact push to eject parts from a conveyor or die. The rear clevis mount allows the cylinder to be positioned at an angle for optimal ejection trajectory.
Gate or Diverter Actuation
Actuates a small diverter gate or chute flap on a material handling line. The CA mount allows the cylinder to pivot as the gate opens and closes, preventing rod side-loading.
Is the Airtac SC80 Standard Cylinder SC80X50CA the Right Cylinder?
Choose the SC80X50CA for high-force short-stroke applications where a pivoting mount is needed. If 2513 N at 0.5 MPa is more force than required, stepping down to the 63 mm bore reduces push force to 1559 N. For higher force demands, the 100 mm bore provides 3927 N at the same pressure. The rear clevis mount is ideal for applications where the cylinder must swing through an arc.
For replacement, match the 80 mm bore, 50 mm stroke, PT port thread, and the CA rear single clevis mounting configuration. This model does not include a built-in magnet, so ensure your existing setup does not require barrel-mounted sensors unless you plan to add external limit switches.
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 SC80X50CA FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. The maximum push force at the 0.9 MPa operating limit is 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
This is a direct replacement for any AirTAC SC80X50CA or another brand's 80 mm bore, 50 mm stroke tie-rod cylinder with a rear single clevis mount and PT1/8 ports. Verify that your mounting pin diameter matches the F-SC80CA clevis bracket and that your application does not require a magnetic piston for sensors.
