The AirTAC SC40 Standard Cylinder SC40X770S is a genuine double-acting standard air cylinder with a Ø40mm bore and 770mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X770S is a double-acting tie-rod cylinder with a 40 mm bore and a long 770 mm stroke, delivering a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration for medium-length linear moves.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The standard TPU seals offer a reliable operating range of -20 to +70 °C with filtered air.

Pushes or diverts packages and components along a conveyor line with 628 N of force, with sensor-confirmed end-of-stroke detection via the built-in magnet.
Operates a sliding safety door or interlock guard with a 770 mm travel, using magnetic sensors to verify the open/closed position before a cycle starts.
Drives a long-reach sorting gate or flipper in a logistics system, where the 1130 N maximum thrust handles medium-weight items reliably.
For applications requiring slightly more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. When replacing an existing cylinder, match five key points: 40 mm bore, 770 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. At this 770 mm stroke, ensure the rod is not subjected to significant side loading; an external linear guide or a guided cylinder is recommended to protect the rod bearing from bending moments.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder provides 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the extending force increases to 1130 N.
Yes. The -S suffix in the model code SC40X770S means a magnet is built into the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
