The AirTAC Airtac SC40 Standard Cylinder SC40X415S is a genuine double-acting standard air cylinder with a Ø40mm bore and 415mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X415S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod family, combining a 40 mm bore with a 415 mm stroke. At 0.5 MPa it generates 628 N pushing and 528 N pulling, while at the maximum operating pressure of 0.9 MPa the push thrust reaches 1130 N. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration for medium-duty linear tasks.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The standard PT1/4 port threads and TPU seals suit filtered-air systems operating from -20 to +70 °C. With a body length A of 142 mm, the total extended length is approximately 557 mm.

The 415 mm stroke and 628 N push force at 0.5 MPa reliably actuates stop gates on package conveyors, halting totes or cartons with the integrated magnet confirming gate position.
Delivers 1130 N of clamping force at 0.9 MPa for CNC woodworking or light metal fabrication jigs, with CMSG sensors verifying clamp engagement on every cycle.
Pushes products off a main line onto a branch conveyor. The built-in magnet enables end-of-stroke sensing to sequence the diverter with upstream and downstream equipment.
Choose the SC40 bore when the 628 N push force at 0.5 MPa fits the load; if the application demands more force, stepping up to the SC50 bore provides 982 N at the same pressure. For strokes of 415 mm, confirm that side loads are minimal or use an external guide rail, as the unsupported 16 mm rod can bend under lateral force.
For a direct replacement, match five points: 40 mm bore, 415 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder delivers 628 N pushing and 528 N pulling. At 0.7 MPa it produces 879 N push, and at the 0.9 MPa maximum operating pressure the push force is 1130 N.
Yes. The -S suffix indicates a built-in magnet inside the piston, specifically designed for mounting AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods for non-contact position detection.
