The AirTAC Airtac SC40 Standard Cylinder SC40X930S is a genuine double-acting standard air cylinder with a Ø40mm bore and 930mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X930S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, featuring a 40 mm bore and a 930 mm stroke. At 0.5 MPa operating pressure, it generates 628 N of push force and 528 N of pull force, making it suitable for medium-duty linear transfer tasks. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the barrel for reliable end-of-stroke detection.
This model uses a 16 mm diameter piston rod with an M12x1.25 rod thread and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, providing smooth deceleration. With a body length A of 142 mm, the total extended length is approximately 1072 mm. It operates on filtered air within a pressure range of 0.15-1.0 MPa and a standard temperature range of -20 to +70 °C using TPU seals.

Actuates a medium-length diverter gate on a packaging line, with the built-in magnet confirming gate position via barrel-mounted sensors.
Pushes components onto an indexing table. The 930 mm stroke clears the feed area, while the 628 N force handles consistent part transfer.
Raises and lowers a stop plate in a gravity conveyor lane. The adjustable cushion absorbs impact at the end of the stroke for quiet operation.
Choose the SC40X930S for applications requiring a 40 mm bore with sensor feedback. If your force requirement exceeds 628 N at 0.5 MPa, consider stepping up to the SC50 bore, which offers 982 N of push force at the same pressure. For lower force needs, the SC32 bore provides 402 N.
For this 930 mm stroke length, carefully evaluate side-loading conditions. Long, unsupported piston rods are susceptible to bending under lateral forces. If the load is not guided externally, use an external guide rail or consider a guided cylinder variant to protect the rod bearings and ensure long service life. When replacing this cylinder, match the bore, stroke, PT1/4 port thread, basic mounting, and the -S magnet option to ensure sensor compatibility.
Quick checklist
At the standard operating pressure of 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, the push force increases to 1130 N.
Yes. The -S suffix in the model code SC40X930S indicates a built-in magnet. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position.
