The AirTAC Airtac SCD Standard Cylinder SCD32X300S 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, 300mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X300S delivers identical push and pull force of 345 N at 0.5 MPa (621 N at 0.9 MPa), thanks to its double-rod design where the 12 mm rod passes through both end caps. This symmetry makes it ideal for applications needing balanced motion in both directions, such as two-sided tooling or transfer mechanisms. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for non-contact position feedback.
With a 300 mm stroke and a body length A of 187 mm, this cylinder provides a compact yet functional footprint for light automation tasks. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, reducing end-of-stroke impact. It operates on 40 µm filtered air from 0.15 to 1.0 MPa, with PT1/8 ports and an M10x1.25 rod thread for easy integration.

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 tool or stop to be mounted on both ends, enabling the cylinder to perform work in both extend and retract strokes with equal force, perfect for symmetrical clamping or pushing.
The integrated magnet (-S) works seamlessly with CMSG/DMSG sensors clamped to the barrel. Use the rear rod extension to trigger a secondary sensor or flag, providing end-of-stroke confirmation without extra brackets.
With 345 N of balanced force, this cylinder is well-suited for small part diverters or transfer gates on conveyor lines, where the return stroke is as critical as the push stroke for resetting the mechanism.
Choose the SCD32 bore for light, balanced push-pull tasks up to 345 N at standard plant pressure. If you need more force, step up to the SCD40, which provides 528 N at the same 0.5 MPa. This double-rod unit is the right choice when you need to mount tooling or a sensor flag on the rear rod; for a simpler single-direction push, the single-rod SC32 is a more economical alternative. The built-in magnet (-S suffix) is factory-installed, saving you the hassle of adding external sensor mounts.
For a direct replacement, match the 32 mm bore, 300 mm stroke, PT1/8 ports, basic mounting, and the magnet option. Since this is a 300 mm stroke, be mindful of potential rod bending under side load on the unsupported 12 mm rod. For applications with significant lateral force, an external guide rail or a guided cylinder is recommended.
Double-rod checklist
No, they are identical. Because the 12 mm piston rod extends through both ends of the cylinder, the effective pressure area is the same in both directions. The force is 345 N at 0.5 MPa and 621 N at 0.9 MPa for both push and pull.
Choose the SCD when you need equal force and speed in both directions, or when you need to mount a tool, stopper, or sensor target on the rear rod. The through-rod also provides better guidance and some resistance to rotation compared to a single-rod cylinder.
