About the Airtac SC50 Standard Cylinder SC50X150SCA
The AirTAC SC50X150SCA is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 150 mm stroke suits medium-reach clamping and positioning tasks, and the built-in magnet allows CMSG/DMSG sensors to track piston position directly on the tie-rod barrel.
This model includes a rear single clevis mount (CA) for pivoting installation, part code F-SC50CA. The 20 mm diameter piston rod and PT1/4 ports provide solid flow, while the 21 mm adjustable air cushion at each end decelerates the 200 kgf-class load smoothly. Body length A is 150 mm, giving a compact extended length of approximately 300 mm.

Where the Airtac SC50 Standard Cylinder SC50X150SCA Is Used
Part Diverter Gate
The pivoting rear clevis mount and 150 mm stroke actuate a diverter flap on a conveyor line, routing packages between lanes with the 982 N push force at 0.5 MPa.
Welding Fixture Clamp
Magnetic piston sensing confirms clamp closure on a welding jig. The 1767 N force at 0.9 MPa holds the workpiece firmly, and the adjustable cushion prevents impact vibration.
Hopper Gate Actuator
Operates a sliding gate on a seed or grain hopper. The CA clevis allows the cylinder to swing as the gate opens, while the -S magnet provides open/closed position feedback to the PLC.
Is the Airtac SC50 Standard Cylinder SC50X150SCA the Right Cylinder?
Choose the SC50 bore when your application needs around 982 N of push force at standard plant pressure. If you require more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 bore provides 628 N. This SC50X150SCA is factory-configured with a built-in magnet for sensor feedback and a rear single clevis (CA) that lets the cylinder pivot during operation.
For a direct replacement, match these five points: 50 mm bore, 150 mm stroke, PT1/4 port thread, rear clevis mounting (F-SC50CA), and the integrated magnet (-S). The 150 mm stroke is well within the standard range, so no external guide is typically required for purely axial loads, but any side force must be managed with an external linear guide.
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 SC50X150SCA 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.
Yes, if the original is a 50 mm bore, 150 mm stroke tie-rod cylinder with a rear single clevis, PT1/4 ports, and a magnetic piston. The clevis bracket is part F-SC50CA. Verify the pin diameter and clevis width match your existing linkage.
