The AirTAC Airtac SCD Standard Cylinder SCD32X160 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, 160mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X160 is a compact double-rod pneumatic cylinder that provides identical force in both directions—345 N at 0.5 MPa—thanks to its 12 mm through-rod subtracting the same area from each piston side. With a 160 mm stroke, it is well-suited for light transfer gates or two-sided tooling where space is limited and symmetric motion is required.
This genuine AirTAC cylinder features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, and a body length of 187 mm (A dimension). The M10x1.25 rod thread on both ends allows identical tooling to be mounted front and rear, and the PT1/8 ports keep the footprint small for integration into tight machine envelopes.

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 rod extending from both ends lets one cylinder drive two mechanisms in opposite directions simultaneously, such as opening and closing a pair of small grippers or gates.
The rear rod provides a convenient mounting point for a sensor flag or cam, enabling end-of-stroke detection without adding brackets to the front tooling.
The dual-rod support improves resistance to rod rotation, making it suitable for light pushing or ejecting applications where the tool must not twist.
Choose the SCD32X160 when you need equal push-pull force and a rear rod for a sensor flag or secondary operation. If the 345 N output at 0.5 MPa is marginal, stepping up to the SCD40 bore provides 528 N at the same pressure. For applications with significant side load, a guided cylinder is a better choice than relying solely on the double-rod bearing support.
This model replaces any AirTAC SCD32X160 of the same bore, stroke, PT port thread, basic mounting, and no magnet. At 160 mm, the stroke is well within the 1000 mm maximum standard stroke for the 32 mm bore, so this is a standard catalog item.
Double-rod checklist
Push and pull forces are equal on a double-rod cylinder. At 0.5 MPa the SCD32X160 delivers 345 N, at 0.7 MPa it is 483 N, and at the maximum operating pressure of 0.9 MPa it reaches 621 N.
Choose the SCD when you need identical force and speed in both directions, or when you need a rear rod extension to mount a sensor, stopper bolt, or secondary tooling. The through-rod also provides better guidance and anti-rotation than a single-rod cylinder of the same bore.
