The AirTAC SC50 Standard Cylinder SC50X900S is a genuine double-acting standard air cylinder with a Ø50mm bore and 900mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X900S is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa (1767 N at 0.9 MPa), making it a strong mid-range actuator for long linear moves. With a 20 mm piston rod, PT1/4 ports, and a 21 mm adjustable air cushion at each end, it decelerates loads smoothly across the full 900 mm stroke.
This model includes the factory-installed -S magnet, so CMSG, DMSG, or EMSG reed and solid-state sensors clip directly onto the tie-rod barrel for non-contact position sensing. The body length A is 150 mm, giving a total extended length of approximately 1050 mm. As a genuine AirTAC SC tie-rod cylinder, it is shorter than an ISO 15552 profile and is a direct replacement only for another SC50 of matching stroke, port, and magnet configuration.

The 900 mm stroke pushes or pulls components between distant conveyor stations. The built-in magnet allows end-of-stroke sensors to confirm transfer completion without physical contact.
Moves a dispensing head along a 900 mm linear path at controlled speeds of 30-800 mm/s. The adjustable cushion protects the tooling from impact at the stroke ends.
Raises and lowers a light gate or stop on a gravity conveyor. The 982 N push force at standard shop air is sufficient for repetitive vertical actuation of light-to-medium barriers.
Choose the SC50 bore when your application needs between 825 N (pull at 0.5 MPa) and 1767 N (push at 0.9 MPa). If you require more force, step up to the SC63 bore, which provides 1559 N push at 0.5 MPa; for a lighter, more compact solution, the SC40 bore offers 628 N at 0.5 MPa. The 900 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
For a long 900 mm stroke, ensure the rod is not subjected to significant side loading, as the unsupported 20 mm rod can bend under lateral force. If side load is unavoidable, use an external linear guide or switch to a guided cylinder. When replacing this unit, match five points: 50 mm bore, 900 mm stroke, PT1/4 port thread, the basic (no bracket) mounting, and the built-in magnet (-S suffix).
Quick checklist
At 0.7 MPa (7 bar) supply pressure, the SC50 bore generates a push force of 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa and scales proportionally with pressure up to the 1.0 MPa maximum operating limit.
Yes. The -S suffix in SC50X900S denotes a built-in magnetic piston ring. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the cylinder's tie-rod barrel for reliable, non-contact end-of-stroke or mid-stroke position detection.
