The AirTAC Airtac SC40 Standard Cylinder SC40X675S is a genuine double-acting standard air cylinder with a Ø40mm bore and 675mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X675S is a double-acting tie-rod cylinder with a 40 mm bore and a 675 mm stroke, pre-fitted with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. Its 16 mm diameter piston rod and PT1/4 port deliver a push force of 628 N at 0.5 MPa, rising to 1130 N at the maximum operating pressure of 0.9 MPa.
With a body length A of 142 mm and a 21 mm adjustable air cushion at each end, this cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The -S suffix equips the barrel with a magnetic band, enabling simple, clamp-on position sensing without external brackets—ideal for stroke confirmation in automated sequences.

The 675 mm stroke and magnetic piston allow precise end-of-stroke sensing to reliably actuate diverter gates on packaging or sortation conveyors, handling mid-weight parcels with the 628 N push force at standard line pressure.
Ideal for pushing components along a 675 mm transfer rail in assembly cells. The built-in magnet enables CMSG sensors to confirm full extension and retraction, ensuring parts are correctly indexed at each station.
Use this cylinder in end-of-line palletising where a 675 mm reach is needed to stop or lift light pallets. The adjustable cushion protects the 16 mm rod and end caps during high-cycle stopping operations.
This 40 mm bore model suits mid-force tasks up to 1130 N. If your load requires more force, stepping up to the SC50 (bore 50 mm) provides 982 N at 0.5 MPa. For lighter, faster applications, the SC32 delivers 402 N at 0.5 MPa. At a 675 mm stroke, ensure the rod is not subjected to side loads; long unsupported rods can bend under lateral force. Use an external linear guide or a guided cylinder if side loading is present.
When replacing an existing cylinder, match five points: 40 mm bore, 675 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This model uses the default TPU seals and PT threads.
Quick checklist
At 0.7 MPa (7 bar) the SC40X675S produces a push force of 879 N. The maximum push force at the 0.9 MPa operating limit is 1130 N. These values are based on the 40 mm bore piston area and assume standard compressed air.
Yes. The -S suffix in the model code indicates a built-in magnet is integrated into the piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without extra mounting hardware.
