The AirTAC Airtac SCD Standard Cylinder SCD63X220S 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, 220mm stroke, PT1/4 ports and adjustable end cushioning.
The SCD63X220S is a double-acting, double-rod pneumatic cylinder that outputs an identical 1402 N of thrust in both directions at 0.5 MPa, rising to 2523 N at 0.9 MPa. Its 20 mm diameter rod passes through both end caps, providing a rear connection point for a sensor flag, stopper bolt, or secondary tooling while ensuring perfectly balanced force and speed for the extend and retract strokes.
This model includes a built-in magnet (-S suffix), allowing you to clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for contactless end-of-stroke detection. With a 220 mm stroke, PT1/4 ports, and an adjustable air cushion length of 28 mm, it is a genuine AirTAC unit built for symmetric linear tasks where mounting a sensor externally is impractical.

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 lets you mount a tooling plate on the front rod and a counterbalance or secondary pusher on the rear rod, creating a balanced shuttle for moving parts between two conveyor lanes.
With the built-in magnet, mount DMSG sensors to confirm both ends of stroke. The equal 2523 N push/pull force at 0.9 MPa makes it ideal for pressing operations that require the same controlled effort in both directions.
The dual-rod support provides better resistance to rod rotation than a single-rod cylinder, making it suitable for simple lifting or guiding tasks where adding external linear guides is not possible, provided side loads are minimal.
Choose the SCD63 bore when your application needs roughly 1400 N of balanced force per direction. If you require more thrust, stepping up to the SCD80 delivers 2268 N at the same 0.5 MPa. For tasks that only need force on the push stroke, the single-rod SC63 is a lighter and more compact alternative. This cylinder is a direct replacement for another AirTAC SCD63X220S matching the 63 mm bore, 220 mm stroke, PT port thread, basic mounting, and the integrated magnet.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 1402 N, at 0.7 MPa it produces 1962 N, and at the maximum operating pressure of 0.9 MPa it produces 2523 N in both directions.
Pick the SCD when you need equal force and speed in both directions, or when you require a rear rod extension to mount a limit switch dog, a manual override knob, or a secondary tool. The through-rod also provides better support for the piston, reducing uneven bushing wear in horizontal applications.
