The AirTAC Airtac SC40 Standard Cylinder SC40X615S is a genuine double-acting standard air cylinder with a Ø40mm bore and 615mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X615S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and a 615 mm stroke, equipped with a built-in magnet for sensor mounting. It produces a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure, driven by a 16 mm diameter piston rod.
This model includes the -S suffix for a factory-installed magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for precise end-of-stroke detection. With a body length A of 142 mm, the total extended length is approximately 757 mm, and the 21 mm air cushion at each end provides adjustable deceleration for smooth cycle rates.

Pushes or diverts medium-weight packages on conveyor lines with 628 N of force at standard shop air, while the built-in magnet signals position to the PLC.
Applies consistent 1130 N clamping force at 0.9 MPa for machining fixtures, with magnetic sensors confirming the clamp is engaged before the cycle starts.
Operates a 615 mm stroke sorting gate in a distribution center, using the -S magnet to provide open/closed confirmation for high-throughput routing.
Select the SC40X615S when your application requires a 40 mm bore with sensor feedback capability. If your force requirement exceeds the 628 N available at 0.5 MPa, consider stepping up to the SC50 series, which provides 982 N at the same pressure. For lower force needs, the SC32 series delivers 402 N.
For this 615 mm stroke, ensure the load is guided externally to prevent side-load bending on the 16 mm rod. When replacing this cylinder, match all five key points: 40 mm bore, 615 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is shorter in overall length than a comparable ISO 15552 cylinder. It is not dimensionally interchangeable. Replace it only with another AirTAC SC tie-rod cylinder matching the 40 mm bore, 615 mm stroke, PT ports, and built-in magnet.
