The AirTAC SC50 Standard Cylinder SC50X75LB is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75LB is a 50 mm bore, 75 mm stroke double-acting tie-rod cylinder from the AirTAC SC series. It generates a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator for industrial automation tasks.
This model is supplied with an LB foot mounting bracket (F-SC50LB) for secure axial surface installation. The 20 mm diameter piston rod and PT1/4 port thread ensure reliable pneumatic connections, while the 21 mm adjustable air cushion at each end decelerates the load smoothly to reduce end-of-stroke impact.

The 982 N push force at standard line pressure is ideal for diverting packages or controlling product flow on medium-duty conveyor lines.
Delivers consistent clamping force for CNC jigs and welding fixtures, with the LB foot mount providing a stable, bolted-down platform.
Suitable for actuating sorting gates and chutes in seed or produce handling equipment, where the TPU seals handle standard temperature ranges.
Select the SC50 when your application requires a force between the SC40 (628 N push at 0.5 MPa) and the SC63 (1559 N push at 0.5 MPa). This 75 mm stroke is well within the 1200 mm maximum standard stroke for the 50 bore. For direct replacement, match five key points: 50 mm bore, 75 mm stroke, PT1/4 port thread, LB foot mounting, and the standard non-magnetic piston.
For strokes exceeding 300 mm, consider an external guide rail or a guided cylinder to protect the 20 mm rod from bending under side loads, as tie-rod cylinders are designed primarily for axial thrust.
Quick checklist
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. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT thread, and LB foot mount.
