The AirTAC SC50 Standard Cylinder SC50X75SN 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 AirTAC SC50X75SN is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 75 mm stroke, a 20 mm diameter piston rod, and a compact 150 mm body length, this model is a precise fit for medium-force clamping and positioning tasks where space is at a premium.
The integrated magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The N suffix specifies NBR (nitrile) seals, making this unit suitable for general industrial environments within the standard -20 to +70 °C temperature range.

The 982 N push force at 0.5 MPa reliably actuates medium-duty diverter gates on packaging and sortation conveyors, with the built-in magnet providing sensor feedback to the PLC.
Ideal for small pneumatic presses and riveting stations, the 75 mm stroke provides a controlled pressing distance, while the NBR seals ensure consistent performance with standard filtered air.
The magnet-equipped barrel allows precise clamp/unclamp position sensing in robotic welding cells, ensuring the 20 mm rod holds the fixture firmly under the 1767 N max force.
Select the SC50 bore when your application requires a push force between 982 N and 1767 N. If your load demands more thrust, stepping up to the SC63 bore provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 bore offers 628 N at the same pressure. This 75 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
For a direct replacement, match these five points: 50 mm bore, 75 mm stroke, PT port thread, the built-in magnet (-S), and the NBR seal material. This tie-rod cylinder is shorter than an ISO 15552 profile and will only interchange with another AirTAC SC series cylinder of the same specifications.
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 with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 standards. It is a direct replacement only for another AirTAC SC50 cylinder with identical bore, stroke, mounting, magnet, and seal options.
