The AirTAC Airtac SCD Standard Cylinder SCD80X80SFA is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø80mm bore, 80mm stroke, PT3/8 ports and adjustable end cushioning.
The SCD80X80SFA is a double-acting, double-rod pneumatic cylinder delivering balanced bidirectional force. With an 80 mm bore and a 25 mm rod extending from both ends, it generates an equal 2268 N of thrust in both push and pull directions at 0.5 MPa, making it ideal for applications where identical force and speed are required in each stroke direction.
This specific configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and an FA front rectangular flange (F-SC80FA) for secure end-face mounting. The 80 mm stroke is cushioned by a 28 mm adjustable air cushion on each end, decelerating the piston smoothly. Its body length A(SCD) is 257 mm, providing a compact yet robust double-rod solution.

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 | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 2268 N force in both directions ensures a transfer shuttle moves with identical speed and power, regardless of travel direction, for consistent part handling.
The built-in magnet allows CMSG/DMSG sensors to be mounted on the rear barrel, using the protruding rear rod as a direct position flag without extra bracketry.
With a 25 mm rod on each end, mount a primary tool on the front and a secondary stripper plate or counter-tool on the rear, both driven by a single, synchronized cylinder.
Choose the SCD80 when you need symmetric actuation force around 2268 N at 0.5 MPa. If your load requires less force, the SCD63 offers 1402 N at the same pressure. For higher force demands, step up to the SCD100, which provides 3681 N. Always consider the double-rod design when you need to attach tooling or a sensor flag to the rear rod, or when the inherent anti-rotation guidance of the through-rod is beneficial, though it is not a substitute for a fully guided cylinder under significant side loads.
For direct replacement, match the 80 mm bore, 80 mm stroke, PT port thread, FA front flange mounting, and the -S magnet option. If your application does not require a rear rod and you need a higher push force from the full piston area, a single-rod SC series cylinder would be a more suitable and cost-effective choice.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 2268 N, at 0.7 MPa it is 3175 N, and at the maximum operating pressure of 0.9 MPa, the force is 4082 N in both directions.
Choose the SCD80 when you need perfectly equal force and speed in both directions, or when you need to utilize the rear rod for mounting a sensor flag, a cam, or secondary tooling. The through-rod also provides better guidance and some resistance to rotation compared to a single-rod cylinder.
