The AirTAC Airtac SCD Standard Cylinder SCD32X1200S 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, 1200mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X1200S is a double-acting, double-rod pneumatic cylinder delivering perfectly symmetrical force and speed in both directions. At 0.5 MPa, it provides 345 N of thrust whether extending or retracting, thanks to its 12 mm through-rod that subtracts the same area from both sides of the piston. This model includes a built-in magnet (-S suffix), allowing easy mounting of CMSG/DMSG/EMSG sensors directly on the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback.
With a 1200 mm stroke, this unit exceeds the standard maximum of 1000 mm for the 32 mm bore, making it a non-standard, made-to-order configuration for applications needing an exceptionally long reach from a compact body. The body length A(SCD) is 187 mm, and the adjustable air cushion at each end is 21 mm, providing smooth deceleration. The rod protrudes from both caps with M10x1.25 male threads, enabling tooling or a mechanical stop to be mounted on the rear rod.

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 allows a single cylinder to push a pallet into a station and simultaneously pull the next one into position, using the rear rod as a secondary actuator.
The dual-rod design provides inherent anti-rotation stability, making this 1200 mm stroke unit suitable for pushing lightweight parts across a wide conveyor without a separate guide rail.
With the built-in magnet, a sensor can be clamped to the barrel to detect the piston's position, while the rear rod provides a convenient physical flag for a secondary hard-wired limit switch.
This 32 mm bore SCD is ideal when you need equal bidirectional force in a very slim profile. If your application requires more thrust, consider stepping up to the SCD40 series, which provides 528 N at the same 0.5 MPa pressure. For applications where the force only needs to be high in one direction, a single-rod SC cylinder will be more compact and cost-effective. Given the 1200 mm stroke, careful attention must be paid to rod buckling and side loading; the through-rod design improves guidance compared to a single rod, but for any significant side load, an external linear guide or a dedicated guided cylinder is required. To replace an existing SCD32X1200S, match the 32 mm bore, 1200 mm stroke, PT ports, basic mounting, and the -S magnet option.
Double-rod checklist
The push and pull forces are identical because the rod passes through both ends. At 0.5 MPa it produces 345 N, at 0.7 MPa it produces 483 N, and at the maximum operating pressure of 0.9 MPa it delivers 621 N in both directions.
Choose an SCD double-rod cylinder when you need equal force and speed in both directions, or when you need to mount a tool, stopper, or sensor flag on the rear rod. The through-rod also provides better support for the piston, reducing uneven wear under side-load-free conditions compared to a single-rod design.
