The AirTAC Airtac SC40 Standard Cylinder SC40X190S is a genuine double-acting standard air cylinder with a Ø40mm bore and 190mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X190S is a double-acting pneumatic cylinder with a 40 mm bore and 190 mm stroke, delivering a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and PT1/4 ports suit medium automation tasks requiring consistent linear thrust.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the tie-rod barrel for non-contact position sensing. The adjustable air cushion at each end decelerates the piston smoothly over the final 21 mm of travel, reducing end-of-stroke impact noise and wear.

Operates diverter gates on packaging conveyors. The 628 N push force at 0.5 MPa reliably shifts product lanes, while the built-in magnet provides end-of-travel confirmation via barrel-mounted sensors.
Applies controlled clamping pressure in woodworking or light metal assembly jigs. The 16 mm rod resists deflection under axial load, and the adjustable cushion prevents part marking on clamp contact.
Positions test tube racks or pipette mechanisms in diagnostic equipment. The sensor-ready barrel enables precise mid-stroke and end-stroke feedback for repeatable liquid handling sequences.
Choose the SC40 when your application needs between 528 N (pull at 0.5 MPa) and 1130 N (push at 0.9 MPa). If you require higher force, step up to the SC50 bore which provides 982 N push at 0.5 MPa; for lighter, more compact needs, the SC32 delivers 402 N. The 190 mm stroke is within the 1200 mm standard maximum for this bore.
For a direct replacement, match five points: 40 mm bore, 190 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic mounting configuration. Always verify the overall extended length (body length A of 142 mm + 190 mm stroke = 332 mm) fits your existing envelope.
Quick checklist
At 0.5 MPa, the cylinder pushes with 628 N and pulls with 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. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position without external brackets.
