The AirTAC Airtac SC40 Standard Cylinder SC40X66S is a genuine double-acting standard air cylinder with a Ø40mm bore and 66mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X66S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 66 mm stroke, delivering 628 N of push force at 0.5 MPa. Its 16 mm diameter rod and M12x1.25 rod thread provide solid mechanical connection, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.
This model includes a built-in magnet (-S suffix), allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for reliable end-of-stroke position sensing. The compact body length A of 142 mm plus the 66 mm stroke keeps the overall extended length manageable for tight machine spaces.

The built-in magnet allows direct mounting of reed switches to confirm full extension or retraction, ideal for part-eject stations on conveyors where cycle verification is required.
Provides 628 N of push force at 0.5 MPa for light pressing, clamping, or staking operations in benchtop assembly fixtures, with sensors confirming tool position.
Drives diverter gates in material handling systems. The magnetic piston enables non-contact sensing to confirm gate position without adding external mechanical flags.
For applications requiring slightly more force, stepping up to the 50 mm bore SC series provides 982 N of push at the same 0.5 MPa pressure. If a shorter overall length is needed, the 32 mm bore offers 402 N. When replacing this cylinder, match five key points: the 40 mm bore, 66 mm stroke, PT port thread, the built-in magnet option, and the basic (no bracket) mounting configuration to ensure a drop-in fit.
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 designates a built-in magnet in the piston. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's tie-rod slots to detect piston position.
