The AirTAC Airtac SC40 Standard Cylinder SC40X815S is a genuine double-acting standard air cylinder with a Ø40mm bore and 815mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X815S is a double-acting pneumatic cylinder with a 40 mm bore and an 815 mm stroke, delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model uses a PT1/4 port and an M12x1.25 rod thread, with a compact body length A of 142 mm. The 815 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore, making it a standard-configuration cylinder ready for immediate integration into automation systems.

The 815 mm stroke and 628 N push force at 0.5 MPa make this cylinder ideal for pushing medium-weight components along conveyor lines or into assembly stations, with sensor feedback confirming full extension.
Deploy the SC40X815S to actuate diverter gates in logistics hubs. The built-in magnet enables precise position sensing to confirm gate status, ensuring reliable package routing at high cycle rates.
Use this cylinder for clamping or lifting operations requiring an extended reach. The adjustable cushion protects the end caps from impact damage during high-speed cycling, extending service life in demanding fixtures.
Choose the SC40 when your application needs a mid-range force between the smaller SC32 (402 N at 0.5 MPa) and the larger SC50 (982 N at 0.5 MPa). For this 815 mm stroke, ensure the load is guided externally or use a guided cylinder if significant side forces are present, as the 16 mm rod can be subject to bending under unsupported side loads at long extensions.
For a direct replacement, match these five points exactly: 40 mm bore, 815 mm stroke, PT1/4 port thread, 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 the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 879 N. The maximum theoretical force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so the mounting dimensions and overall envelope are different. It is a direct replacement only for another AirTAC SC tie-rod cylinder with identical bore, stroke, port thread, magnet option, and mounting.
