About the Airtac SC50 Standard Cylinder SC50X175CA
The SC50X175CA is a double-acting AirTAC SC tie-rod cylinder with a 50 mm bore and 175 mm stroke, factory-assembled with a rear single clevis (CA) bracket for pivoting applications. At 0.5 MPa air pressure it produces 982 N of push force, and at the maximum operating pressure of 0.9 MPa thrust rises to 1767 N, driven by a 20 mm diameter piston rod.
This model uses the standard TPU seals for a working temperature range of -20 to +70 °C and PT1/4 threaded ports. The 175 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, and the adjustable air cushion (21 mm cushion length) decelerates the piston smoothly at end-of-travel. The CA clevis mount, part F-SC50CA, allows the cylinder body to pivot, accommodating angular misalignment in the application.

Where the Airtac SC50 Standard Cylinder SC50X175CA Is Used
Agricultural Implement Actuation
Operates chute deflectors, hopper doors, or bale tensioners on farming equipment. The rear clevis mount allows the cylinder to pivot as the linkage moves, and 982 N of force handles medium-duty mechanical adjustments.
Conveyor Diverter Gates
Swings a diverter gate or plough on a belt conveyor to sort packages or bulk material. The 175 mm stroke provides ample travel for wide belts, and the clevis mount absorbs the arc of the swinging gate.
Clamp & Fixture Pivot Arms
Drives a pivoting clamp arm on a welding fixture or assembly jig. The SC50X175CA delivers consistent clamping force and the adjustable cushion reduces impact and noise when the clamp reaches its clamped position.
Is the Airtac SC50 Standard Cylinder SC50X175CA the Right Cylinder?
Choose the SC50 bore when your application needs between 500 and 980 N of push force at typical shop air pressure. If the load exceeds 980 N, step up to the SC63 bore (1559 N at 0.5 MPa); if the load is lighter and a more compact cylinder is preferred, the SC40 bore provides 628 N at 0.5 MPa. The 175 mm stroke is a standard length, keeping lead times short.
For a reliable replacement, match five attributes: 50 mm bore, 175 mm stroke, PT1/4 port thread, the CA rear single clevis mounting style, and the absence of a barrel magnet. The CA clevis is designed for pivoting motion; ensure the mating pin is correctly sized for the clevis eye and that the cylinder is free to swing through its full arc without binding.
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 SC50X175CA 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, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf (1961 N).
No. The SC50X175CA is a double-acting cylinder and does not lock or hold position when air pressure is exhausted or the directional valve is centered. If the application requires load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
