About the Airtac SC50 Standard Cylinder SC50X320CA
The SC50X320CA is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure). Its 50 mm bore and 320 mm stroke suit medium-duty linear actuation where a rear pivot mount is required.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and a 21 mm adjustable air cushion at each end. The CA suffix denotes a rear single clevis mount (F-SC50CA), allowing the cylinder body to pivot during operation. Ports are PT1/4 and the standard TPU seals provide a -20 to +70 °C operating range.

Where the Airtac SC50 Standard Cylinder SC50X320CA Is Used
Dump Trailer Gate Actuation
The rear clevis mount allows the cylinder to pivot as it opens and closes a hopper or trailer gate, handling the 982 N push force needed to move bulk materials.
Clamping & Fixturing
Provides consistent 1767 N clamping force at 0.9 MPa for welding jigs and assembly fixtures, with the clevis mount simplifying installation on pivoting clamp arms.
Part Diverter on Conveyors
Uses the 320 mm stroke to push a diverter gate across a conveyor line. The CA mount absorbs the arc motion, preventing rod bending in this medium-speed sorting task.
Is the Airtac SC50 Standard Cylinder SC50X320CA the Right Cylinder?
Choose the SC50 when your application needs roughly 1000 N of push force at standard plant pressure. If you require more force, stepping up to the SC63 bore provides 1559 N at 0.5 MPa. For strokes of 300 mm and above, always check for side loading—a 20 mm rod extending 320 mm can experience bending stress if the load is not guided. Use an external guide rail or a guided cylinder if side forces are present.
This cylinder is a direct replacement for an existing AirTAC SC50X320CA unit. When replacing, match five points: 50 mm bore, 320 mm stroke, PT1/4 ports, the CA rear clevis mounting accessory, and the standard (non-magnetic) piston.
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 SC50X320CA 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 reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X320CA is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. The adjustable air cushions only decelerate the piston at the end of stroke. For load holding, you must add an external rod lock or a pilot-operated check valve.
