The AirTAC Airtac SC40 Standard Cylinder SC40X15S is a genuine double-acting standard air cylinder with a Ø40mm bore and 15mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X15S is a compact-stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 15 mm stroke suit short-throw clamping, ejecting, and positioning tasks where space is limited.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke detection. The 16 mm diameter piston rod and PT1/4 ports provide a robust connection for high-cycle industrial applications.

The 15 mm stroke and 628 N force at 0.5 MPa are ideal for compact pneumatic clamps on CNC jigs and assembly fixtures, with magnetic sensors confirming clamp engagement.
Delivers a quick, controlled push to eject lightweight parts from a conveyor or sorting chute. The built-in magnet enables cycle counting via barrel-mounted sensors.
Suited for precise 15 mm linear positioning of stops or gates in packaging machinery, where the 16 mm rod provides adequate stiffness for the short extension.
Choose the SC40 bore when 628 N of push force at 0.5 MPa meets the load requirement. If the application demands more force, stepping up to the SC50 bore provides 982 N at the same pressure. For side loads or moments, pair this cylinder with an external guide rail, as the tie-rod design is intended for axial loads.
When replacing an existing cylinder, match five key points: 40 mm bore, 15 mm stroke, PT1/4 port thread, the basic (no bracket) mounting configuration, and the built-in magnet (-S) for sensor compatibility. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa (approx. 72.5 psi), the push force is 628 N (about 64 kgf). At the maximum operating pressure of 0.9 MPa, the thrust increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet, making the SC40X15S compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors. These sensors clamp onto the barrel tie-rods without additional brackets.
