The AirTAC Airtac SC40 Standard Cylinder SC40X300SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 300mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X300SN is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 300 mm stroke, combined with a 16 mm diameter piston rod, is well-suited for medium-reach clamping and material transfer tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The NBR (-N) seals provide reliable sealing for standard industrial air, and the PT1/4 port thread ensures straightforward pneumatic connection.

The 300 mm stroke moves components between conveyor lines or workstations, with the built-in magnet providing sensor feedback for automated sequencing.
Applies 628 N of force at 0.5 MPa to secure workpieces during light machining or assembly, where NBR seals handle standard shop air conditions.
Operates diverter gates in material handling systems. The magnetic piston allows position confirmation at both ends of the stroke for reliable sortation.
For applications requiring more force, stepping up to the SC50 bore provides 982 N of push force at 0.5 MPa. At a 300 mm stroke, ensure the rod is not subjected to significant side loads; if side loading is unavoidable, an external linear guide should be used to prevent rod bearing damage and ensure long service life.
When replacing an existing cylinder, match five critical points: 40 mm bore, 300 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting configuration. This ensures a direct, drop-in replacement for another AirTAC SC40X300SN unit.
Quick checklist
At 0.5 MPa, the cylinder provides 628 N extending (push) and 528 N retracting (pull). The maximum operating force at 0.9 MPa is 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. To guarantee a drop-in replacement, verify that the original unit also has a 40 mm bore, 300 mm stroke, PT ports, a built-in magnet, and a basic mount. The NBR seals in this model are standard for non-high-temperature environments.
