The AirTAC Airtac SCD Standard Cylinder SCD63X96 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 96mm stroke, PT1/4 ports and adjustable end cushioning.
The SCD63X96 is a double-acting, double-rod pneumatic cylinder where the piston rod extends from both ends, guaranteeing identical thrust in each direction. At 0.5 MPa, it produces a balanced 1402 N push and pull force, rising to 2523 N at the 0.9 MPa maximum operating pressure, making it ideal for tasks needing symmetric motion.
With a 63 mm bore and a 20 mm through-rod, this model features a 96 mm stroke—a non-standard length that requires a made-to-order configuration. The body length A(SCD) is 210 mm, and adjustable air cushioning over 28 mm at each end cap decelerates the piston smoothly, protecting end-of-stroke components without locking the load.

Specifications follow the official AirTAC SCD (double-rod) datasheet. Because the rod runs through both caps, the effective area is (bore² − rod²) in both directions. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
Push and pull are EQUAL on a double-rod cylinder — both chambers lose the rod area, so effective area = (bore² − rod²) each way. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

The equal push/pull force of 1402 N at 0.5 MPa drives a transfer shuttle back and forth with perfectly symmetric speed and thrust, ideal for moving parts between two parallel conveyor lines.
Use the rear rod to mount a second tool or a stripper plate, performing a two-stage pressing operation where the forward stroke does the work and the return stroke strips the part off the tool.
The through-rod provides inherent anti-rotation stability for a pusher plate, while the rear rod end can carry a sensor flag for end-of-stroke confirmation without adding a bracket to the front tooling.
Choose the SCD63 when your application demands equal force in both directions and the 1402 N output at 0.5 MPa fits your load. If you need more power, stepping up to the SCD80 provides 2268 N at the same pressure. For applications where only one rod end is needed, the single-rod SC63 series is a simpler, more compact alternative.
As a direct replacement, match this unit to another AirTAC SCD double-rod cylinder with identical 63 mm bore, 96 mm stroke, PT port thread, and basic mounting. If your stroke is longer than 300 mm, assess the unsupported rod for potential buckling under compressive loads and consider an external guide rail to prevent bending.
Double-rod checklist
Because the SCD is a double-rod cylinder, the piston area is identical on both sides. The force is 1402 N for both push and pull at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at the maximum operating pressure of 0.9 MPa.
Select the SCD63 when you need perfectly equal force and speed in both directions, or when you need to mount tooling, a stopper, or a sensor target on the rear rod end. A single-rod SC63 has a higher push force due to the full piston area but a lower pull force, making it less suitable for fully symmetric applications.
