The AirTAC SC40 Standard Cylinder SC40X380S is a genuine double-acting standard air cylinder with a Ø40mm bore and 380mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X380S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke automation moves.
This 40 mm bore model features a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to mount directly on the tie-rod barrel for contactless position feedback. With a 380 mm stroke, the total extended length reaches approximately 522 mm (body length A of 142 mm plus stroke), fitting compact machine frames where sensor confirmation is required.

The 380 mm stroke pushes components off a conveyor with 628 N of force, while the built-in magnet triggers CMSG sensors to confirm full extension and retraction for reliable sorting logic.
Applies controlled clamping force to workpieces in CNC fixtures. The sensor-ready barrel enables end-of-stroke verification, preventing machine cycle start until the part is securely clamped.
Transfers cartons or trays across a 380 mm span into a sealing station. The adjustable air cushion softens the stop at both ends, reducing noise and mechanical shock in high-cycle packaging lines.
Choose the SC40 when your application needs up to 628 N at standard plant pressure. If side loads or bending moments are present on this 380 mm stroke, consider an external guide rail or a guided cylinder—long unsupported rods can deflect under off-axis force. For higher force, step up to the SC50 bore (982 N push at 0.5 MPa).
For direct replacement, match five points: 40 mm bore, 380 mm stroke, PT port thread, basic mounting (no bracket), and the -S magnet option. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder provides 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix denotes a built-in magnet, making the SC40X380S compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp onto the tie-rod barrel. Without the -S option, the cylinder cannot trigger external magnetic sensors.
