About the Airtac SC50 Standard Cylinder SC50X1320
The SC50X1320 is a double-acting pneumatic cylinder with a 50 mm bore and an extended 1320 mm stroke, built on the compact AirTAC SC tie-rod platform. At the standard 0.7 MPa operating pressure, it generates 1374 N of push force, scaling to a maximum of 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod.
This model features a non-standard stroke length exceeding the 1200 mm maximum for the 50 mm bore, making it a made-to-order solution for applications requiring extra-long linear travel. It includes PT1/4 ports, adjustable pneumatic cushioning, and a standard TPU seal for operation in temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1320 Is Used
Long-Stroke Material Rejection
Pushes defective products off a wide conveyor line, using the 1320 mm stroke to span the full belt width with a single actuator.
Vertical Panel Press
Provides the 1374 N force at 0.7 MPa to clamp large wooden panels during a gluing cycle, with the long stroke accommodating deep workpieces.
Bulk Bag Filling Gate
Operates a slide gate at the bottom of a large filling hopper, using the extended stroke to fully open and close the discharge chute.
Is the Airtac SC50 Standard Cylinder SC50X1320 the Right Cylinder?
Select the SC50 when your application needs the 982 N push force at 0.5 MPa that this 50 mm bore provides. If you require a more compact cylinder for lower loads, step down to the 40 mm bore (628 N at 0.5 MPa); for significantly higher force in the same mounting footprint, consider the 63 mm bore (1559 N at 0.5 MPa).
For this 1320 mm stroke, external guide rails or a guided cylinder are strongly recommended. The long, unsupported 20 mm rod is susceptible to bending and buckling under side loads, which can cause premature seal wear and rod damage. For a direct replacement, match the 50 mm bore, 1320 mm stroke, PT1/4 port thread, basic mounting, and the absence of a magnet.
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 SC50X1320 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 increases to 1767 N.
No, the maximum standard stroke for a 50 mm bore SC cylinder is 1200 mm. The 1320 mm stroke is a non-standard, made-to-order length, and external guides are highly recommended to protect the piston rod from bending.
