The AirTAC Airtac SC40 Standard Cylinder SC40X400S is a genuine double-acting standard air cylinder with a Ø40mm bore and 400mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X400S is a genuine AirTAC double-acting tie-rod cylinder with a 40 mm bore and a 400 mm stroke, delivering a push force of 628 N at 0.5 MPa (up to 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 tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The standard PT1/4 port and TPU seals suit filtered-air systems operating from -20 to +70 °C.

The 400 mm stroke and built-in magnet for end-of-travel sensing make this cylinder ideal for diverting packages on conveyor lines, where mid-range force and reliable position feedback are essential.
Delivers up to 1130 N at 0.9 MPa for light pressing, clamping, or holding fixtures in assembly jigs. The adjustable cushion protects tooling at the end of the 400 mm stroke.
Suited for vertical or horizontal transfer mechanisms in pick-and-place units. The magnetic piston allows sensors to confirm full extension and retraction for safe interlocking.
Choose the SC40X400S when your application needs roughly 628 N of push force. If you require more power, stepping up to the 50 mm bore provides 982 N at the same 0.5 MPa pressure. For strokes of 300 mm or longer, always check for side loads—an unsupported 16 mm rod at 400 mm extension can bend under lateral force; use an external linear guide or a guided cylinder if the load is not purely axial.
For drop-in replacement, match five points: 40 mm bore, 400 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This SC series 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 the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in the model code SC40X400S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's tie-rod slots to detect piston position without additional brackets.
