About the Airtac SC50 Standard Cylinder SC50X1450
The AirTAC SC50X1450 is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1450 mm stroke, built for applications that require a long reach with consistent linear force. At the standard operating pressure of 0.9 MPa, it generates a push force of 1767 N, driven by a 20 mm diameter piston rod with M16x1.5 male threads for tooling attachment.
This model is a non-standard stroke length, exceeding the standard maximum of 1200 mm for the 50 mm bore, and is typically made to order. The tie-rod construction keeps the body length compact at 150 mm, resulting in a total extended length of approximately 1600 mm. It features PT1/4 threaded ports and an adjustable pneumatic cushion with a 21 mm cushion length to decelerate the piston smoothly at end-of-travel.

Where the Airtac SC50 Standard Cylinder SC50X1450 Is Used
Long-Reach Material Transfer
Pushes or pulls lightweight components across a wide 1450 mm gap on packaging or assembly lines where a compact body is needed at the mounting point.
Vertical Gantry Actuation
Provides the vertical Z-axis motion on a light-duty gantry, using the 1767 N force at 0.9 MPa to raise and lower a sensor or dispensing head with a guided carriage.
Bin Pushing and Sorting
Acts as a long-stroke pusher in logistics sorting systems, diverting bins or cartons off a main conveyor line with controlled, cushioned end-of-stroke deceleration.
Is the Airtac SC50 Standard Cylinder SC50X1450 the Right Cylinder?
Select the SC50X1450 when your application needs a long 1450 mm stroke with the force profile of a 50 mm bore, which provides 982 N of push at 0.5 MPa. If you require higher force for the same stroke, stepping up to a 63 mm bore (1559 N at 0.5 MPa) is recommended; for a shorter, standard stroke with similar force, the 40 mm bore (628 N at 0.5 MPa) may suffice.
For a stroke of this length, the 20 mm rod is susceptible to bending under side loads. It is critical to ensure the load is guided externally on linear rails or to use a guided cylinder variant to prevent rod bearing damage and premature seal wear. As a direct replacement, match the 50 mm bore, 1450 mm stroke, PT port thread, and basic mounting configuration of an existing AirTAC SC cylinder.
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 SC50X1450 FAQ
At 0.7 MPa operating pressure, the SC50X1450 delivers a theoretical push force of 1374 N and a pull force of 825 N on the retract stroke, using its 20 mm rod.
No, 1450 mm is a non-standard stroke for the 50 mm bore, whose maximum standard stroke is 1200 mm. To prevent rod buckling or bending on such a long stroke, you must guide the load externally with a linear rail or rod guide; the cylinder's rod bearing is not designed to support side loads.
