The AirTAC Airtac SC40 Standard Cylinder SC40X290S is a genuine double-acting standard air cylinder with a Ø40mm bore and 290mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X290S is a double-acting pneumatic cylinder with a 40 mm bore and 290 mm stroke, delivering 628 N of push force at 0.5 MPa (1130 N at the maximum operating pressure of 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The standard PT1/4 port thread and TPU seals suit filtered-air environments from -20 to +70 °C.

The 290 mm stroke and sensor-ready magnet make this cylinder ideal for diverting cartons on packaging conveyors, where end-of-stroke confirmation is required for cycle sequencing.
Delivers 628 N of consistent clamping force for jigs and fixtures in automated assembly cells, with the built-in magnet enabling sensor feedback to the PLC.
Suitable for pushing or lifting components between conveyor levels in material handling systems, where the adjustable cushion protects the load from end-of-stroke shock.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If a shorter, more compact unit is acceptable, the 32 mm bore SC32 series offers 402 N at the same pressure. Always match the replacement cylinder across five points: bore, stroke, port thread (PT), mounting accessory, and the presence of the magnet (-S).
At a 290 mm stroke, the 16 mm rod is well-supported for axial loads, but any side loading requires an external guide or a guided cylinder to prevent rod bearing wear and bending.
Quick checklist
At the standard 0.5 MPa operating pressure, 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 indicates a built-in magnet, which is specifically designed for use with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors. These sensors clamp directly onto the cylinder's tie-rod barrel for reliable, non-contact position detection.
