The AirTAC Airtac SCD Standard Cylinder SCD32X270STC 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, 270mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X270STC is a double-acting, double-rod pneumatic cylinder where the piston rod extends from both ends, guaranteeing identical push and pull force of 345 N at 0.5 MPa. This specific model includes a built-in magnet and a centre trunnion mount (TC), supplied with the TCM1 bracket for pivoting applications. The 12 mm diameter through-rod provides enhanced guidance and anti-rotation compared to a single-rod design.
With a 270 mm stroke, this cylinder is well-suited for tasks requiring a compact, equal-force actuator on both sides, such as operating a two-sided clamp or transferring small parts. The body length (A) is 187 mm, and it features an adjustable pneumatic cushion of 21 mm to decelerate the piston smoothly at each end. Operating on filtered air at 0.15-1.0 MPa, it uses PT1/8 ports and an M10x1.25 rod thread for easy tooling attachment.

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.

The through-rod design allows a tooling plate to be mounted on both ends, enabling a single cylinder to shuttle parts between two parallel conveyors with perfectly synchronized motion.
Delivers an equal 345 N clamping force from both ends at 0.5 MPa, ideal for centering or clamping a workpiece from two opposite sides simultaneously in a welding or assembly jig.
The dual-rod configuration provides inherent anti-rotation for a pusher plate, while the built-in magnet on the barrel allows a CMSG sensor to be mounted on the rear side to detect stroke completion.
Select the SCD32X270 when you need a compact 32 mm bore actuator that provides equal, controlled motion in both directions. If your force requirement is slightly higher, stepping up to the SCD40 series will provide 528 N of force at the same 0.5 MPa pressure. For applications where only one end of the cylinder is accessible for work, a single-rod SC series cylinder is a more economical and simpler choice. This SCD model is a direct replacement for another AirTAC SCD32 double-rod cylinder matching the 270 mm stroke, PT port, centre trunnion mount, and built-in magnet.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. The force is 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at the maximum operating pressure of 0.9 MPa.
Choose an SCD when you need equal force and speed in both directions, or when you must mount a tool, stopper, or sensor flag on the rear rod. The dual-rod design also provides better side-load resistance and anti-rotation than a single-rod cylinder.
