The AirTAC SC50 Standard Cylinder SC50X750SN 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 SC50X750SN is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks. This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets.
With a 750 mm stroke and a compact body length A of 150 mm, the total extended length is approximately 900 mm. The cylinder is fitted with NBR (nitrile) seals (-N suffix), offering a balanced cost-performance ratio for general industrial air service within the standard -20 to +70 °C temperature range. PT1/4 ports are standard, and the maximum operating pressure is 1.0 MPa.

Pushes bins or cartons across a 750 mm wide roller conveyor, with sensor confirmation at each end of travel for reliable sortation control.
Applies consistent 982 N clamping force to hold workpieces during welding or assembly, with magnetic sensors verifying clamp engagement before the cycle starts.
Operates a sliding gate on a bulk material hopper, using the long 750 mm stroke for full open/close and sensors to signal gate position to the PLC.
For applications needing slightly less force, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). If higher force is required, the 63 mm bore provides 1559 N at the same pressure. At 750 mm stroke, the 20 mm rod is robust, but avoid unsupported side loads; for guided linear motion, pair this cylinder with an external guide rail or consider a guided cylinder assembly.
When replacing an existing cylinder, match five key points: 50 mm bore, 750 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the NBR seal material. This ensures direct form and function with another AirTAC SC tie-rod unit.
Quick checklist
At 0.5 MPa, the cylinder provides 982 N push force and 825 N pull force. At the maximum operating pressure of 0.9 MPa, push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet in the piston. This allows AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing.
