The AirTAC SC50 Standard Cylinder SC50X750SH 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 SC50X750SH is a double-acting AirTAC SC series tie-rod cylinder with a 50 mm bore and a 750 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for mid-range automation tasks.
This specific model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton seals (-H suffix) that extend the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU seals would degrade. The body length A is 150 mm, giving a total extended length of 900 mm for this stroke.

The Viton seals allow this SC50X750SH to operate reliably in ovens, autoclaves, or near heat-sealing equipment where ambient temperatures reach up to 150°C, controlling a sliding gate or damper with its 750 mm stroke.
With 1767 N of force at 0.9 MPa, this cylinder can eject freshly molded or cast parts from a hot die onto a conveyor. The built-in magnet enables end-of-stroke sensing to confirm ejection before the next cycle.
The integrated magnetic piston allows CMSG/DMSG sensors to provide closed-loop confirmation of clamp engagement in automated welding or assembly fixtures, even under elevated thermal loads.
Choose the SC50 when your application needs a force between 982 N and 1767 N. If you require more force, step up to the SC63 bore which provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 bore offers 628 N at the same pressure. For this 750 mm stroke, ensure the rod is protected from side loads—consider an external linear guide or a guided cylinder if the load is not perfectly axial, as long, unsupported rods are susceptible to bending under lateral force.
For a direct replacement, match five key points: 50 mm bore, 750 mm stroke, PT port thread, the -S magnet option for sensors, and the -H Viton seal for high-temperature compatibility. This is a non-ISO tie-rod cylinder, so it is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 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 with a shorter body length 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 the same 750 mm stroke, PT ports, magnet option, and Viton seals.
