The AirTAC Airtac SC40 Standard Cylinder SC40X424S is a genuine double-acting standard air cylinder with a Ø40mm bore and 424mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X424S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the 424 mm stroke is well within the 1200 mm maximum standard stroke for this bore size.
A built-in magnet (the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The cylinder uses PT1/4 ports, an adjustable air cushion (21 mm cushion length), and operates on filtered air from 0.15 to 1.0 MPa. The body length A is 142 mm, giving an extended length of approximately 566 mm.

The 424 mm stroke and 628 N push force at 0.5 MPa suit medium-reach diverter gates on packaging conveyors. The built-in magnet enables end-of-stroke confirmation via CMSG sensors.
Provides consistent clamping and part-presentation strokes in assembly cells. The adjustable cushion protects tooling at the end of the 424 mm travel, and magnetic sensors sequence the next operation.
Pushes totes or cartons off a line with 628 N of force. The tie-rod construction handles repetitive cycling, and the sensor-ready barrel simplifies integration into automated sortation systems.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N push at 0.5 MPa. If space is tight and less force is acceptable, the 32 mm bore SC32 offers 402 N. At a 424 mm stroke, the 16 mm rod is moderately long—check side-load conditions and consider an external linear guide or a guided cylinder if the load is not purely axial. When replacing an existing unit, match five points: 40 mm bore, 424 mm stroke, PT1/4 ports, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
Quick checklist
At 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, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, so AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors clip directly onto the barrel tie-rods for position feedback without external brackets.
