The AirTAC Airtac SCD Standard Cylinder SCD32X150 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, 150mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X150 is a compact double-rod air cylinder that outputs an identical 345 N of thrust in both directions when supplied with 0.5 MPa air, thanks to its through-rod construction. With a 12 mm rod extending from both ends and a 150 mm stroke, it is well-suited for light-duty two-sided tooling, symmetrical clamping, or applications where a rear rod end is needed for a sensor flag or manual stop.
This genuine AirTAC SCD series model features a 187 mm body length and adjustable pneumatic cushioning at both ends to decelerate the piston smoothly. The PT1/8 ports and M10x1.25 rod threads make it easy to integrate into compact automation cells, providing balanced, repeatable motion without the force asymmetry of a single-rod 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 | 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 tooling to be mounted on both ends, enabling the SCD32X150 to perform a work stroke in each direction, such as pushing a component into a fixture and then retracting a stop pin from the opposite side.
Identical push and pull force of 345 N at 0.5 MPa ensures even clamping pressure from both directions, making this cylinder ideal for holding thin-walled or delicate parts that could be distorted by unequal force.
The rear rod extension provides a convenient, out-of-the-way location to mount a sensor flag or cam for end-of-stroke detection, keeping the primary work area clear for the main tooling.
Choose the SCD32X150 when your mechanism needs equal push and pull force in a small footprint. If 345 N at 0.5 MPa is marginal, stepping up to the SCD40 bore provides 528 N at the same pressure. For applications where only one end of the rod is accessible, the single-rod SC32 series is a simpler, more cost-effective choice. This double-rod unit should not be used as a guided cylinder under significant side load; if the 150 mm stroke creates a bending moment on the exposed rods, add an external linear guide.
For direct replacement, match the 32 mm bore, 150 mm stroke, PT port thread, basic mounting configuration, and the absence of a magnet. Any genuine AirTAC SCD32X150 with these same specifications will be dimensionally and functionally identical.
Double-rod checklist
Because the piston rod passes through both end caps, the effective pressure area is identical in both directions. The SCD32X150 produces 345 N of force when extending and retracting at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at the maximum operating pressure of 0.9 MPa.
Select the SCD32 when you need equal force and speed in both directions, or when you require a rear rod extension for mounting sensors, stops, or secondary tooling. The double-rod design also provides better rod bearing support than a single-rod cylinder, though it is not a substitute for an externally guided unit under side loads.
