The AirTAC SC50 Standard Cylinder SC50X700S is a genuine double-acting standard air cylinder with a Ø50mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X700S is a double-acting pneumatic cylinder with a 50 mm bore and a 700 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the tie-rod barrel for precise, non-contact position sensing.
The 20 mm diameter piston rod and PT1/4 port ensure robust flow and mechanical strength for medium-duty linear tasks. With a 21 mm adjustable air cushion at each end, the cylinder decelerates the piston smoothly, reducing impact noise and extending service life. Its body length A is 150 mm, resulting in a total extended length of approximately 850 mm for this genuine AirTAC actuator.

The 700 mm stroke pushes or diverts products across wide conveyor sections. The built-in magnet enables end-of-stroke sensing to sequence gates reliably.
Clamps and positions components in welding cells. The 1767 N force at 0.9 MPa provides strong holding, while magnetic sensors confirm clamp closure before the cycle starts.
Extends to release a single pallet from a stack. The long 700 mm reach and sensor feedback ensure only one pallet is dispensed per actuation.
Choose the SC50 bore for applications needing around 1000 N of push force at standard plant pressure; if your load is lighter, stepping down to a 40 mm bore (628 N at 0.5 MPa) can reduce air consumption and physical size. For a 700 mm stroke, ensure the load is guided or supported externally—long, unsupported strokes on a 20 mm rod can experience bending moments under side load, which accelerates rod bearing and seal wear. For direct replacement, match five points: 50 mm bore, 700 mm stroke, PT1/4 port thread, basic mounting (no bracket), and the -S magnet for sensor compatibility.
Quick checklist
At 0.5 MPa the push force is 982 N and the pull force is 825 N. At 0.7 MPa it pushes 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code indicates a factory-installed magnet in the piston. This allows you to mount AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel for position detection without any additional brackets.
