The AirTAC Airtac SCD Standard Cylinder SCD63X160 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 AirTAC SCD63X160 is a double-acting, double-rod pneumatic cylinder where the piston rod extends from both ends, giving you identical push and pull force of 1402 N at 0.5 MPa. With a 20 mm diameter rod on each side and a 160 mm stroke, it is built for tasks that need a tooling plate or sensor flag on the rear rod, or where symmetric force prevents uneven wear on the bearings.
This 63 mm bore model uses a PT1/4 port, an M16x1.5 rod thread, and an adjustable air cushion of 28 mm at each end to decelerate the piston smoothly. Its body length A(SCD) is 210 mm, making it longer than a single-rod SC of the same stroke because the rod passes completely through both end caps.

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.

Related types: SC (single rod), SCJ (adjustable stroke), SCT (multi-position). SCD mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Mount a gripper on the front rod and a counterbalance or second tool on the rear rod for balanced, high-cycle part shuttling where force must be identical in both directions.
Use the equal 2523 N thrust at 0.9 MPa to drive a clamp from both ends of the cylinder, ensuring perfectly synchronized, non-rotating movement without a complex linkage.
The dual-rod design provides inherent anti-rotation guidance, making it suitable for pushing or ejecting parts where a single-rod cylinder's piston would need an external guide to prevent twisting.
Choose the SCD63 when you need the 1402 N force class at 0.5 MPa and a through-rod design. If you need more thrust, step up to the SCD80 which provides 2268 N; for a lighter, more compact build, the SCD50 offers 825 N. If your application only requires force from one end, a single-rod SC series cylinder is a simpler, more cost-effective choice.
For a 160 mm stroke, rod bending under side load is usually minimal, but always avoid direct lateral force on the exposed rod ends. To replace this cylinder, match the 63 mm bore, 160 mm stroke, PT port thread, basic mounting, and ensure the replacement is a genuine AirTAC SCD double-rod unit.
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 is 1962 N, and at the maximum operating pressure of 0.9 MPa, the force reaches 2523 N. The theoretical force at 1.0 MPa is 286 kgf.
Choose the SCD when you need a rear rod extension for mounting sensors, a stroke-stop, or a second tool. It also provides equal force and speed in both directions, which is critical for symmetric processes, and the dual-rod support offers better guidance against side loads than a single-rod cylinder alone.
