The AirTAC Airtac SCD Standard Cylinder SCD32X75S 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, 75mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X75S is a compact double-rod pneumatic cylinder that delivers an equal 345 N of force in both the extend and retract directions at 0.5 MPa, thanks to its 12 mm through-rod subtracting the same area from each piston face. With a 75 mm stroke and a body length A(SCD) of 187 mm, this tie-rod unit fits neatly into fixtures where a rear rod is needed for a sensor flag or secondary tooling.
This model includes the built-in -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact end-of-stroke detection. The adjustable air cushion at each end (21 mm) decelerates the piston smoothly, and the PT1/8 ports keep the plumbing compact for light automation tasks.

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 lets you mount tooling on both ends for simultaneous push-pull operations, such as opening and closing a dual-gate mechanism with one cylinder.
With the built-in magnet, a DMSG sensor on the rear rod confirms full retraction in tight spaces where the front cap is inaccessible, ideal for sequencing confirmation.
The dual-rod support provides inherent anti-rotation, making it suitable for light pressing or stamping fixtures where a single rod might twist under offset loads.
Choose the SCD32X75S when you need a 32 mm bore double-rod cylinder with integrated position sensing and a 75 mm working stroke. If your load requires more thrust, stepping up to the SCD40 series provides 528 N at 0.5 MPa. For applications where only one rod end is needed, the single-rod SC32 series is a more economical choice.
This double-rod design offers better guidance than a single-rod cylinder, but it is not a substitute for a fully guided cylinder under significant side loads. For direct replacement, match the 32 mm bore, 75 mm stroke, PT1/8 ports, basic mounting, and the -S magnet option.
Double-rod checklist
The forces are identical in both directions because the rod passes through both ends. At 0.5 MPa, it produces 345 N; at 0.7 MPa, 483 N; and at the maximum operating pressure of 0.9 MPa, it delivers 621 N.
Pick the SCD when you need equal force and speed in both directions, a rear rod end for mounting a sensor flag or stopper bolt, or better rod guidance to resist rotation. The SC single-rod series is preferred when only one working end is required and a slightly lower cost is desired.
