The AirTAC Airtac SC40 Standard Cylinder SC40X745S is a genuine double-acting standard air cylinder with a Ø40mm bore and 745mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X745S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa). Its 40 mm bore and 745 mm stroke suit medium-duty linear tasks where a compact, non-ISO 15552 body is preferred. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for reliable end-of-stroke detection.
This model uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at each end. With a body length A of 142 mm, the total extended length is approximately 887 mm. The standard TPU seals provide an operating temperature range of -20 to +70 °C.

The 745 mm stroke and 628 N push force at 0.5 MPa allow this cylinder to act as a robust stop gate or diverter arm on packaging conveyors, where mid-range force and moderate reach are needed.
With a built-in magnet for sensor confirmation, the SC40X745S provides reliable part clamping in woodworking or light metalworking jigs, ensuring the clamp is fully engaged before machining starts.
Ideal for pushing totes or boxes off a gravity roller lane in warehouse sorting systems. The 16 mm rod and adjustable cushion handle the repetitive impact smoothly.
Choose the SC40 bore when your application needs around 628 N of force at 0.5 MPa. If you require more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore provides 402 N. At 745 mm stroke, the rod is extended significantly—ensure side loads are minimal or use an external guide to prevent rod bending and premature bearing wear.
For replacement, match five key points: 40 mm bore, 745 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration. This SC cylinder is shorter than an ISO 15552 cylinder and is dimensionally interchangeable only with another AirTAC SC40 tie-rod cylinder of the same configuration.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, push force increases to 879 N. The maximum theoretical force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in SC40X745S indicates a built-in magnet. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be mounted directly on the barrel tie-rods to detect piston position.
