About the Airtac SC50 Standard Cylinder SC50X150CB
The AirTAC SC50X150CB is a double-acting tie-rod cylinder with a 50 mm bore and 150 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and PT1/4 port thread suit medium-force pneumatic tasks, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.
This model is factory-assembled with a rear double clevis (CB) mounting, part code F-SC50CB, allowing the cylinder to pivot on a fork bracket at the cap end for articulated motion. The standard TPU seals provide a reliable operating temperature range of -20 to +70 °C, and the total extended body length is approximately 300 mm (150 mm body length A + 150 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X150CB Is Used
Conveyor Diverter Gate
The 982 N push force at 0.5 MPa actuates a medium-duty diverter gate on a packaging line, with the rear clevis pivot absorbing misalignment during the 150 mm stroke.
Clamp & Fixture Actuation
Provides consistent clamping force for CNC fixtures or welding jigs, where the double clevis mount allows the cylinder body to swing into position without binding.
Hopper Door Control
Operates a discharge door on a small agricultural hopper or chute, using the 150 mm stroke for full open/close motion and the clevis mount for easy installation on a pivoting bracket.
Is the Airtac SC50 Standard Cylinder SC50X150CB the Right Cylinder?
Choose the SC50 bore when your application needs roughly 982 N of push force at standard plant air; if you require more force, stepping up to the SC63 bore provides 1559 N at the same 0.5 MPa. For this 150 mm stroke, the rod bearing and piston support are well within standard limits, but always align the load axially to prevent side-load wear on the rod bushing. When replacing an existing cylinder, match five points: 50 mm bore, 150 mm stroke, PT1/4 port thread, rear double clevis (CB) mounting, and confirm no magnet sensor is needed (this code has no -S suffix).
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 SC50X150CB 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. These values are based on the 50 mm bore and 20 mm rod diameter.
The CB suffix means this cylinder comes with a rear double clevis bracket (F-SC50CB) designed for pivoting motion. If you need rigid surface mounting, order the basic version or choose an LB foot mount instead.
