The AirTAC Airtac SCD Standard Cylinder SCD80X160SLB 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, 160mm stroke, PT3/8 ports and adjustable end cushioning.
This SCD80X160SLB double-rod cylinder delivers an identical 2268 N of thrust in both extend and retract directions at 0.5 MPa, thanks to its through-rod design where the 25 mm rod subtracts the same area from each piston face. The 160 mm stroke is well within the 1500 mm maximum for the 80 mm bore, and the body length A(SCD) is 257 mm, giving you a compact overall envelope for a dual-output actuator.
The built-in magnet (denoted by the S in the model code) allows CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing, while the LB foot mount provides a stable, surface-mounted installation. At the full 0.9 MPa operating pressure, the output rises to 4082 N, making this a robust choice for tasks needing symmetric force from both ends of the cylinder.

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 25 mm rod extending from both ends lets you attach identical grippers or nests on each side, moving parts between two parallel conveyor lines with perfectly synchronized motion and equal force in both directions.
The dual-rod support provides better resistance to twisting than a single-rod cylinder. Use the rear rod extension with an external guide block for a simple, non-rotating push application without a full guided cylinder.
With the integrated magnet and an EMSG sensor mounted on the rear end of the barrel, you can detect the piston's position using the rear rod's movement, keeping the front work area clear of sensors and cables.
Choose the SCD80 bore when your application needs around 2268 N of balanced force at standard plant pressure; if you can accept a lower force of roughly 1402 N, stepping down to the SCD63 bore saves space and air consumption. For higher demands, the SCD100 bore provides 3681 N at the same 0.5 MPa. This double-rod unit is the right call when you need to mount tooling or a sensor flag on the rear rod, but if you only need force from one end, a single-rod SC80 is a simpler, more cost-effective alternative. For a drop-in replacement, match the 80 mm bore, 160 mm stroke, PT port thread, SCD-specific LB foot mount, and the -S magnet option exactly.
Double-rod checklist
The push and pull forces are identical because the piston rod passes through both ends. At 0.5 MPa it produces 2268 N, at 0.7 MPa it produces 3175 N, and at the maximum operating pressure of 0.9 MPa it produces 4082 N in both directions.
Choose the SCD when you need to perform work on both ends of the cylinder simultaneously, such as driving two mechanisms with one actuator, or when you need the rear rod for mounting a sensor cam or a mechanical stop. The dual-rod support also offers better side-load resistance than a single-rod SC, though it is not a replacement for a fully guided cylinder under heavy moment loads.
