The AirTAC Airtac SC40 Standard Cylinder SC40X65SFA is a genuine double-acting standard air cylinder with a Ø40mm bore and 65mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X65SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 65 mm stroke suit short linear moves in compact automation cells.
This model includes a built-in magnet for barrel-mounted CMSG/DMSG/EMSG sensors and a front rectangular flange (FA) for rigid panel mounting. The 16 mm diameter piston rod and PT1/4 ports provide reliable cycling with adjustable air cushioning at both ends.

The 65 mm stroke and magnetic piston enable precise end-of-stroke sensing for small part handling on assembly stations.
Front-flange mounting secures the cylinder to a conveyor frame, using 628 N of push force to actuate lightweight product diverters.
Clean, oil-free air operation and sensor feedback make this cylinder ideal for clamping test fixtures or vials in automated lab equipment.
For higher force, step to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact actuator, the SC32 offers 402 N. The FA front flange (F-SC40FA) bolts directly to a machine panel, keeping the cylinder body cantilevered. When replacing, match bore, stroke, PT port thread, FA mount, and the -S magnet option to ensure sensor compatibility.
Quick checklist
At 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 reaches 1130 N.
Yes. The -S suffix denotes a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel's sensor groove to detect piston position.
