About the Airtac SC50 Standard Cylinder SC50X450CA
The AirTAC SC50X450CA is a double-acting tie-rod cylinder with a 50 mm bore and 450 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. This model features a 20 mm diameter piston rod with an M16x1.5 knuckle thread and an adjustable air cushion length of 21 mm to decelerate the piston smoothly at end of stroke.
Configured with a rear single clevis (CA) mount, this cylinder is designed to pivot during operation, accommodating angular movement of the attached load. The body length A is 150 mm, resulting in a total extended length of approximately 600 mm. It operates on filtered air within a standard temperature range of -20 to +70 °C using durable TPU seals and PT1/4 ports.

Where the Airtac SC50 Standard Cylinder SC50X450CA Is Used
Agricultural Machinery
Operates chute diverters and hopper gates on harvesters and planters, where the rear clevis mount allows the cylinder to pivot freely as the mechanism arcs.
Conveyor Diverter Arms
Swings a diverter gate on a packaging line. The 982 N force at 0.5 MPa reliably redirects parcels, and the clevis mount simplifies installation into a pivoting linkage.
Welding Fixture Clamps
Powers a pivoting clamp arm in a robotic welding cell. The adjustable cushion ensures a quiet, low-impact stroke end, preventing vibration that could disturb the weld puddle.
Is the Airtac SC50 Standard Cylinder SC50X450CA the Right Cylinder?
Select the SC50X450CA when your application requires a mid-range force actuator that can pivot from a rear mounting point. If your force requirement is lower, consider stepping down to the 40 mm bore which provides 628 N at 0.5 MPa; for higher demands, the 63 mm bore offers 1559 N at the same pressure. The 450 mm stroke is within the 1200 mm maximum standard stroke for this bore.
For a stroke of this length, ensure the rod is protected from significant side loads, as an unsupported 20 mm rod can be subject to bending moments. Use an external guide or a self-guided tooling plate if lateral forces are present. For direct replacement, match the 50 mm bore, 450 mm stroke, PT port thread, CA rear clevis mounting (part F-SC50CA), and the absence of a 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 SC50 Standard Cylinder SC50X450CA FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
It is a direct replacement for another AirTAC SC50 tie-rod cylinder with a 450 mm stroke, PT ports, and a CA rear single clevis mount. Ensure the original also used a standard TPU seal and had no built-in magnet, as this model does not include a magnetic piston for sensors.
