The AirTAC Airtac SC40 Standard Cylinder SC40X80S is a genuine double-acting standard air cylinder with a Ø40mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X80S is a double-acting AirTAC tie-rod cylinder with a 40 mm bore and 80 mm stroke, factory-equipped with a built-in magnet. The magnet allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke detection without external brackets.
This model generates 628 N of push force and 528 N of pull force at 0.5 MPa, rising to 1130 N push at 0.9 MPa. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration. With a body length A of 142 mm, the total extended length is approximately 222 mm, making it a compact choice for short linear moves.

The 80 mm stroke and sensor-ready magnet make it ideal for compact part-stop gates on conveyors, where the controller needs confirmation the stop is fully raised or lowered.
Delivers 628 N at 0.5 MPa for consistent workholding. The built-in magnet lets you mount sensors to verify clamp engagement before a machining cycle starts.
Use the SC40X80S to push finished parts off a fixture. The -S magnet provides clean position feedback to the PLC, ensuring the ejector has fully retracted before the next component is loaded.
Choose the SC40 bore when your application needs roughly 600 N of thrust at standard plant air. If you require more force, step up to the SC50 which delivers 982 N push at 0.5 MPa; for a lighter, more compact solution, the SC32 provides 402 N. The 80 mm stroke is standard for this bore.
To replace an existing cylinder, match five points: 40 mm bore, 80 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa air pressure the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet inside the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the barrel tie-rods to detect piston position without any additional mounting hardware.
