The AirTAC SC50 Standard Cylinder SC50X630 is a genuine double-acting standard air cylinder with a Ø50mm bore and 630mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X630 is a 50 mm bore, 630 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. At 0.5 MPa it provides 982 N of push force and 825 N on the pull stroke, making it a capable mid-range actuator for medium-length linear movements. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end ensure smooth deceleration without metal-to-metal impact.
This model uses the standard TPU/NBR seal package rated for -20 to +70 °C and comes with PT1/4 threaded ports. The body length A is 150 mm, giving a total extended length of approximately 780 mm. As a genuine AirTAC cylinder, it is built for reliable industrial service with filtered compressed air at 0.15-1.0 MPa.

Actuates diverter gates on medium-width conveyors, using the 630 mm stroke to sweep product across lanes with controlled cushioning at end positions.
Pushes strip or blank material into stamping presses, where the 982 N force at 0.5 MPa handles moderate feed loads and the long stroke accommodates deep tooling.
Moves a pallet layer stop or squaring plate across a 630 mm range, aligning stacked goods before wrapping or strapping in logistics automation.
With 982 N of push force at 0.5 MPa, the SC50X630 sits between the smaller SC40 (628 N) and the larger SC63 (1559 N). If your load requires more force, stepping up to a 63 mm bore nearly doubles the output; if you need a more compact body, the 40 mm bore may suffice. At 630 mm stroke, the 20 mm rod is unsupported over a significant length—evaluate side loads carefully and consider an external linear guide or a guided cylinder if the rod will experience lateral forces.
To replace an existing SC50X630, match five points: 50 mm bore, 630 mm stroke, PT1/4 port thread, the basic mounting configuration (no integral bracket), and the absence of a magnet. If the original cylinder had a magnet, order SC50X630-S instead.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force rises to 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf (1961 N), but the recommended maximum operating pressure is 0.9 MPa, yielding 1767 N of push force.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder. It is not a direct replacement for ISO 15552 cylinders. It directly replaces another AirTAC SC50 tie-rod cylinder with the same bore, stroke, PT ports, and basic mounting, or a functionally equivalent tie-rod cylinder with matching dimensions.
