About the Airtac SC50 Standard Cylinder SC50X180CA
The SC50X180CA is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), making it a solid mid-range actuator for general automation. Its 180 mm stroke is paired with a 20 mm diameter piston rod and an adjustable air cushion (21 mm length) to decelerate the load smoothly at end-of-travel.
This configuration includes a rear single clevis (CA) mount, allowing the cylinder body to pivot during operation, which is ideal for applications where the load follows an arc. The body length A is 150 mm, and the total extended length is approximately 330 mm.

Where the Airtac SC50 Standard Cylinder SC50X180CA Is Used
Part Diverter
Actuates a pivoting gate or diverter arm on a conveyor line, using the rear clevis mount to swing through an arc for reliable product sorting.
Clamp Arm Actuation
Powers a pivoting clamp arm on a welding or assembly fixture, where the 982 N force securely holds parts and the clevis allows the cylinder to self-align.
Hopper Gate Control
Opens and closes a discharge gate on a small hopper or chute, with the pivoting action providing the necessary lever motion for material flow control.
Is the Airtac SC50 Standard Cylinder SC50X180CA the Right Cylinder?
Choose the SC50X180CA when your application needs a pivoting mount and around 100 kgf of force. If you need more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore offers 628 N. For strokes of 180 mm, side-loading is generally manageable, but always ensure the load is guided externally if any lateral force is present to protect the rod bearing and seals.
For a direct replacement, match these five points: 50 mm bore, 180 mm stroke, PT port thread, rear single clevis (CA) mounting, and the standard non-magnetic piston. The CA mount uses the F-SC50CA accessory bracket.
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 SC50X180CA 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 at 1.0 MPa is 200 kgf.
No. The SC50X180CA is a double-acting cylinder and will not hold position if pressure is lost or the valve is centered. The piston can drift or drop. For load holding, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
