The AirTAC Airtac SC40 Standard Cylinder SC40X1050S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1050mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1050S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa, scaling to 1130 N at the maximum operating pressure of 0.9 MPa. Its 40 mm bore and 1050 mm stroke make it a practical choice for long-reach material transfer or sorting gates where a compact body length is not the primary constraint.
This model includes a factory-installed magnet (denoted by the -S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The 16 mm diameter piston rod, PT1/4 ports, and 21 mm adjustable air cushion are standard for the 40 mm bore, and the total extended length is approximately 1192 mm (142 mm body length A + 1050 mm stroke).

Pushes or pulls components across a wide conveyor gap, with sensor feedback confirming end-of-stroke position.
Operates a diverter flap on a packaging line, using the magnet for cycle counting and jam detection.
Deploys a stop blade over a meter from the cylinder body, cushioned at both ends to reduce impact noise.
For a 40 mm bore at 0.5 MPa, the push force is 628 N. If your load requires more force, stepping up to the 50 mm bore (SC50) provides 982 N push at the same pressure. For lighter, faster applications, the 32 mm bore (SC32) offers 402 N push. The 1050 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore.
At this stroke length, the 16 mm rod is susceptible to bending under side loads. Use an external linear guide or a guided cylinder assembly to protect the rod bearing and ensure long seal life. When replacing an existing cylinder, match five points: 40 mm bore, 1050 mm stroke, PT1/4 port thread, the built-in magnet (-S), and your required mounting accessory.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The -S suffix indicates a built-in magnet. You can clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel to detect piston position without additional brackets.
