About the Airtac SC50 Standard Cylinder SC50X400CA
The SC50X400CA is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. With a 50 mm bore and a 400 mm stroke, it features a 20 mm diameter piston rod and PT1/4 port connections, making it a robust actuator for medium-duty linear motion tasks.
This model is configured with a CA rear single clevis mount (part F-SC50CA), allowing the cylinder to pivot during operation and accommodating angular misalignment. The adjustable pneumatic cushion at each end decelerates the piston smoothly over a 21 mm travel, reducing end-of-stroke impact. The standard TPU seals provide reliable operation within a temperature range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X400CA Is Used
Agricultural Machinery
Operates chutes, gates, and levers on harvesters and planters. The rear clevis mount allows the cylinder to swing with the linkage, and the 982 N force handles heavy mechanical actuation.
Part Diverter Gates
Pivots a diverter gate on a conveyor line to sort packages. The 400 mm stroke provides ample travel for wide conveyors, and the adjustable cushion ensures quiet, low-impact shifting.
Welding Fixture Clamping
Powers a pivoting clamp arm in a robotic welding cell. The single clevis mount fits tight pivot points, and the 20 mm rod resists weld spatter deflection during high-cycle clamping.
Is the Airtac SC50 Standard Cylinder SC50X400CA the Right Cylinder?
Select the SC50 bore when your application requires a force between 628 N (the push force of the smaller SC40 at 0.5 MPa) and 982 N. For higher force requirements, stepping up to the SC63 bore provides 1559 N of push force at the same pressure. For this 400 mm stroke, ensure the rod is not subjected to significant side loads; if side loading is unavoidable, use an external guide rail or a guided cylinder to prevent rod bending and premature seal wear.
To ensure a correct direct replacement, match five key specifications: 50 mm bore, 400 mm stroke, PT1/4 port thread, the CA rear single clevis mounting style, and the absence of a built-in magnet. This cylinder is a direct replacement for another AirTAC SC50X400CA or a tie-rod cylinder with identical mounting and port geometry.
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 SC50X400CA FAQ
At 0.7 MPa operating pressure, the theoretical push force is 1374 N, and the pull force is 1155 N (calculated from the 825 N pull force at 0.5 MPa). The maximum operating force at 0.9 MPa is 1767 N push.
No. The SC50X400CA is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the stroke end; it does not lock the rod. For load holding, you must add a pilot-operated check valve or an external mechanical rod brake.
