The AirTAC Airtac SCD Standard Cylinder SCD32X80 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø12mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø32mm bore, 80mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X80 is a double-acting pneumatic cylinder where the piston rod extends from both ends, giving identical push and pull force in each direction. At 0.5 MPa, this 32 mm bore unit outputs 345 N of thrust both ways, making it ideal for symmetrical transfer mechanisms or fixtures where you need to mount tooling on the rear rod.
With an 80 mm stroke, this model uses a 12 mm diameter rod and PT1/8 ports. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, while the tie-rod construction keeps the body length A(SCD) to a compact 187 mm.

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 | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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.

Operates a transfer shuttle or clamp where a tool must be mounted on both ends of the cylinder, providing perfectly balanced force and speed in each stroke direction.
The dual-rod design offers improved resistance to rod rotation compared to a single-rod cylinder, useful for simple pressing or aligning operations without a full external guide.
The protruding rear rod provides a convenient surface to mount a sensor flag or cam, enabling end-of-stroke detection without attaching anything to the moving load on the front rod.
Choose the SCD32X80 when your application needs equal force in both directions and a rear rod for a sensor flag or secondary tool. If you need more thrust, step up to the 40 mm bore SCD40, which provides 528 N at the same pressure. For purely linear push tasks where only one rod end is used, the single-rod SC32 series is a lighter, more cost-effective alternative. This double-rod cylinder is a direct dimensional replacement for another AirTAC SCD32X80 with matching PT ports and basic mounting.
Double-rod checklist
Because the rod passes through both ends, the effective piston area is identical on both sides. The SCD32X80 produces 345 N of force in both the push and pull directions at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at the maximum operating pressure of 0.9 MPa.
Choose the SCD when you need to attach tooling, stops, or sensors to the rear rod, or when your process requires perfectly equal force and speed in both directions. The through-rod also provides better guidance than a single rod, but it is not a substitute for a fully guided cylinder under high side loads.
