The AirTAC SC50 Standard Cylinder SC50X750H is a genuine double-acting standard air cylinder with a Ø50mm bore and 750mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X750H is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With a 50 mm bore and 750 mm stroke, it is well-suited for medium-duty linear tasks requiring a long reach. The body length A is 150 mm, making the total extended length approximately 900 mm.
This model is equipped with Viton (FKM) seals, designated by the 'H' suffix, which shifts the operating temperature range to 0 to +150 °C. This makes it a robust choice for hot environments where standard TPU seals would degrade. The 20 mm diameter rod with M16x1.5 thread provides solid column strength for pushing applications, and the adjustable air cushion at each end decelerates the piston smoothly.

The Viton seals allow this cylinder to operate reliably in ovens, autoclaves, or near heat sources up to 150°C, where standard seals would fail.
With a 750 mm stroke, it efficiently pushes or lifts products between distant conveyor lines or workstations in automated assembly.
Provides the long, linear motion needed to open and close chutes or gates on agricultural machinery, handling dusty conditions with durable tie-rod construction.
For applications needing more force, stepping up to a 63 mm bore provides 1559 N of push force at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore offers 628 N. At a 750 mm stroke, side loads must be managed carefully; an unsupported 20 mm rod is vulnerable to bending. Use an external linear guide or a guided cylinder assembly if the load is not perfectly axial.
When replacing this cylinder, match five key points: the 50 mm bore, the 750 mm stroke, the PT port thread, the basic (no bracket) mounting, and the Viton seal material. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the theoretical 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. These forces are based on the 50 mm bore and 20 mm rod diameter.
No. The SC50X750H is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. The piston can drift or drop. For load holding, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
