About the Airtac SC50 Standard Cylinder SC50X300CB
The AirTAC SC50X300CB is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 50 mm bore and 20 mm rod diameter provide a robust platform for medium-duty pneumatic tasks requiring a 300 mm stroke.
This model comes factory-equipped with a rear double clevis (CB) mounting, part F-SC50CB, allowing the cylinder body to pivot during operation. The adjustable air cushion (21 mm) decelerates the piston smoothly at end-of-stroke, reducing impact stress on the assembly.

Where the Airtac SC50 Standard Cylinder SC50X300CB Is Used
Linkage Actuation
The rear double clevis mount allows the cylinder to swing, making it ideal for actuating pivoting linkages on agricultural equipment like chute diverters or bin gates.
Part Diverters
Use the 300 mm stroke to push items off a conveyor line. The pivoting CB mount simplifies installation in tight spaces where a fixed foot mount would bind.
Clamping & Welding Fixtures
Provides consistent clamping force in jigs and fixtures. The adjustable cushion prevents impact vibration that could disturb weld quality or part alignment.
Is the Airtac SC50 Standard Cylinder SC50X300CB the Right Cylinder?
For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the 40 mm bore offers 628 N. At 300 mm stroke, ensure the rod is not subjected to significant side load—if lateral forces are present, use an external guide rail or a guided cylinder to prevent rod bearing wear and bending. When replacing this cylinder, match the 50 mm bore, 300 mm stroke, PT1/4 port thread, CB rear double clevis mounting, and confirm the magnet-free configuration.
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 SC50X300CB 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.
This specific model (SC50X300CB) includes the rear double clevis (CB) for pivoting applications. If you need a rigid, fixed mount, select the basic (no mount code), LB foot mount, or FA/FB flange mount variants instead. The clevis can be removed, but the cylinder body length A of 150 mm remains the same.
