The AirTAC Airtac SCD Standard Cylinder SCD63X160S 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, 160mm stroke, PT1/4 ports and adjustable end cushioning.
The SCD63X160S is a double-acting, double-rod pneumatic cylinder that outputs exactly the same force in both directions—1402 N at 0.5 MPa—because the 20 mm rod passes through both end caps. This symmetry makes it ideal for applications where a tool or sensor flag must be mounted on the rear rod, or where balanced thrust is required for a two-sided operation.
With a 160 mm stroke and a body length A of 210 mm, this model includes a built-in magnet (-S suffix) so you can directly mount CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact end-of-stroke detection. The adjustable air cushion (28 mm) decelerates the piston smoothly at both ends, protecting your tooling at the full 0.15-1.0 MPa operating range.

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 through-rod design delivers equal push and pull force, making it perfect for driving a tool on the front rod while a counterweight or secondary operation is mounted on the rear rod.
With the built-in magnet, a CMSG or DMSG sensor on the barrel detects piston position without needing a flag on the front rod, keeping the work zone clear for tooling.
The dual-rod support provides better guidance than a single-rod cylinder, helping to resist rotation in simple push-and-align tasks without a full guided cylinder.
This 63 mm bore model generates 1402 N of force at 0.5 MPa. If your load requires less thrust, stepping down to the 50 mm bore (825 N at 0.5 MPa) can reduce air consumption and physical size. For higher force, the 80 mm bore provides 2268 N. If you only need to push from one end, a single-rod SC series cylinder is a simpler, more cost-effective choice. For direct replacement, match the 63 mm bore, 160 mm stroke, PT ports, and the SCD double-rod configuration; the -S magnet option must also be matched if your existing setup uses barrel-mounted sensors.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it outputs 1402 N, at 0.7 MPa it is 1962 N, and at the maximum operating pressure of 0.9 MPa it delivers 2523 N in both directions.
Choose the SCD when you need equal force and speed in both directions, or when you need a rear rod extension to mount a sensor flag, a mechanical stop, or secondary tooling. The through-rod also provides better bearing support and inherent anti-rotation compared to a single-rod cylinder of the same bore.
