Airtac SCD Standard Cylinder SCD32X150S
The AirTAC Airtac SCD Standard Cylinder SCD32X150S 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.

About the Airtac SCD Standard Cylinder SCD32X150S
The SCD32X150S is a double-acting, double-rod pneumatic cylinder delivering perfectly symmetrical motion. With a 12 mm rod passing through both end caps, the effective piston area is identical in both directions, producing an equal 345 N of force at 0.5 MPa for both extension and retraction.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The 150 mm stroke is well within the 1000 mm maximum for the 32 mm bore, and the body length (A dimension) is 187 mm, making it a compact solution for dual-sided tooling or rear-mounted stroke flags.
Airtac SCD Standard Cylinder SCD32X150S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD32X150S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø32 mm |
| Rod diameter | Ø12 mm (both ends) |
| Stroke | 150 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke | Up to 1000 mm |
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.
Theoretical Output Force (Ø32mm, double rod)
| 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.

Where the Airtac SCD Standard Cylinder SCD32X150S Is Used
Reciprocating Transfer Shuttles
The equal force and speed in both directions ensure smooth, consistent shuttling of small parts between two fixed stops, with the rear rod available to trigger a limit switch.
Non-Rotating Alignment Pins
Use the dual-rod guidance to resist piston rotation, making it suitable for pushing alignment pins or keys where orientation must be maintained without a complex external guide.
Sensor-Controlled Two-Sided Actuation
The integrated magnet works with barrel-mounted sensors to confirm end-of-stroke on both ends, while the rear rod extension can carry a secondary tool or a visual position indicator.
Is the Airtac SCD Standard Cylinder SCD32X150S the Right Cylinder?
Choose this 32 mm bore when your application needs balanced push-pull force around 345 N at 0.5 MPa. If you need more thrust, stepping up to the 40 mm bore provides 528 N each way at the same pressure. This double-rod design is ideal when you need to mount a tool or sensor on the rear rod, but remember that a through-rod provides better guidance than a single rod—it is not a replacement for an externally guided cylinder if significant side loads are present. For direct replacement, match the 32 mm bore, 150 mm stroke, PT port thread, basic mounting, and the -S magnet option.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCD Standard Cylinder SCD32X150S FAQ
Because the piston rod extends through both ends of the cylinder, the push and pull forces are identical. At 0.5 MPa you get 345 N, at 0.7 MPa you get 483 N, and at the maximum operating pressure of 0.9 MPa the force reaches 621 N in both directions.
Choose the SCD when you need perfectly equal force and speed in both directions, or when you need to mount tooling, a sensor flag, or an adjustable stop on the rear rod. The through-rod also provides better bearing support and inherent anti-rotation compared to a single-rod cylinder of the same size.
