The AirTAC SC50 Standard Cylinder SC50X283S is a genuine double-acting standard air cylinder with a Ø50mm bore and 283mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X283S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure. With a 50 mm bore and 283 mm stroke, it uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports, making it a compact yet powerful actuator for medium-duty linear tasks.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position sensing. The total extended body length is approximately 433 mm (150 mm body length A plus 283 mm stroke), and the adjustable air cushion at each end provides a 21 mm deceleration zone to reduce impact noise and wear.

The 283 mm stroke and 982 N push force at 0.5 MPa are well-suited for diverting cartons or totes on conveyor lines. The built-in magnet lets you add sensors to confirm gate open/closed position without external brackets.
Delivers up to 1767 N of clamping force at 0.9 MPa for holding workpieces during machining or assembly. The adjustable cushion protects the fixture from hammering at the end of the 283 mm stroke.
Ideal for pushing or lifting bins and trays in automated storage systems. The M16x1.5 rod thread accepts standard rod-end accessories, and the magnet-equipped barrel simplifies sensor integration for sequence control.
Choose the SC50X283S when your application needs around 982 N of push force at standard shop air; if you require more force, step up to the SC63 bore (1559 N at 0.5 MPa), or down to the SC40 (628 N) for lighter, faster-cycling loads. For strokes of 300 mm or longer on a 20 mm rod, evaluate side-load and rod-bearing bending—an external guide rail or a guided cylinder is recommended when the rod must support off-axis loads.
To ensure a direct replacement, match five points: 50 mm bore, 283 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor mounting, and the basic (no accessory) mounting configuration. This is a tie-rod cylinder, not an ISO 15552 profile unit; it is shorter and not dimensionally interchangeable with ISO 15552 cylinders.
Quick checklist
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa push force rises to 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 (approx. 1960 N), but AirTAC rates operation only up to 1.0 MPa.
Yes. The -S suffix in SC50X283S means a magnet is built into the piston, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional mounting hardware.
