The AirTAC Airtac SC Standard Cylinders SC40X500S is a genuine double-acting standard air cylinder with a Ø40mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X500S is a double-acting tie-rod cylinder with a 40 mm bore and a long 500 mm stroke, delivering about 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. The -S suffix means a magnet is built into the piston, so CMSG, DMSG or EMSG position sensors can clamp directly onto the barrel for end-of-stroke or mid-stroke signalling without any external bracket.
This 500 mm stroke model uses a 16 mm rod, PT1/4 ports, an adjustable 21 mm cushion at each end, and reaches a total extended length of roughly 642 mm (body length A of 142 mm plus stroke). Speed range is 30-800 mm/s at 0.15-1.0 MPa with air filtered to 40 um, and the standard TPU seals cover -20 to +70 C.

A 500 mm stroke sweeps cartons or rejected parts across a full conveyor lane, while the built-in magnet feeds a CMSG sensor signal back to the PLC at each end of travel.
With about 628 N of push at 0.5 MPa, the SC40X500S raises small trays, chutes and product platforms over a half-metre lift in packaging and assembly lines.
The long reach suits sliding guards, pusher arms and clamping fixtures on machines where the sensor magnet lets the controller confirm full retract before the next cycle starts.
At 628 N push (0.5 MPa) the 40 mm bore sits between the 32 mm bore (402 N) and the 50 mm bore (982 N). If your load needs more than roughly 550 N at 0.5 MPa with margin, step up to the SC50; if you are under about 350 N, the SC32 saves space and air. With a 500 mm stroke the 16 mm rod is fairly slender, so keep side load off the rod and use an external guide or a guided cylinder whenever the tooling can bind or the load is not perfectly in line.
Replacing an existing unit? Match all five points: 40 mm bore, 500 mm stroke, PT1/4 port thread (or G if the old cylinder was -G), the mounting accessory, and the magnet option (-S). The SC is a compact tie-rod cylinder, not an ISO 15552 profile cylinder, so it is shorter than an ISO 15552 unit of the same bore and is not dimensionally interchangeable with one.
Quick checklist
At 0.5 MPa it pushes with about 628 N and pulls with about 528 N. At 0.7 MPa push force rises to roughly 879 N, and at the 0.9 MPa maximum operating pressure it reaches about 1130 N. The theoretical maximum is 128 kgf at 1.0 MPa.
It is a direct replacement only for another AirTAC SC or tie-rod cylinder with the same 40 mm bore, 500 mm stroke, PT1/4 port, mounting accessory and -S magnet; it is not an ISO 15552 drop-in. At 500 mm the 16 mm rod is long and slender, so support the load with an external guide or a guided cylinder and keep side loads off the rod bearing.
