Airtac SCD Standard Cylinder SCD32X175
The AirTAC Airtac SCD Standard Cylinder SCD32X175 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, 175mm stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD32X175
The AirTAC SCD32X175 is a double-acting, double-rod pneumatic cylinder where the piston rod extends from both ends, delivering perfectly balanced force in each direction. At 0.5 MPa, it provides 345 N of thrust both extending and retracting, making it ideal for applications requiring identical speed and power for two-sided operations.
With a 12 mm diameter rod passing through both caps and a 21 mm adjustable air cushion at each end, this 175 mm stroke model handles light, synchronized tasks smoothly. Its body length A(SCD) is 187 mm, and it operates reliably between -20 and +70 °C with the default TPU seals.
Airtac SCD Standard Cylinder SCD32X175 Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD32X175 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø32 mm |
| Rod diameter | Ø12 mm (both ends) |
| Stroke | 175 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 SCD32X175 Is Used
Two-Sided Actuation
Operates tooling or clamps on both ends of the cylinder simultaneously, ensuring perfectly synchronized motion without complex linkages.
Anti-Rotation Pusher
The dual-rod design provides inherent resistance to rod rotation, useful for pushing parts where orientation must be maintained without an external guide.
Rear Sensor Flag Mount
The rear rod extension offers a convenient, clean location to mount a sensor flag for end-of-stroke detection without interfering with the primary tooling.
Is the Airtac SCD Standard Cylinder SCD32X175 the Right Cylinder?
Choose the SCD32X175 when your mechanism needs equal actuation force from both sides of the piston, such as a dual-ended tooling fixture. If your load requires more thrust, the SCD40 bore steps up to 528 N at the same pressure. For applications where force is only needed in one direction, the single-rod SC series is a lighter and more compact alternative. As a direct replacement, match the 32 mm bore, 175 mm stroke, PT port thread, and basic mounting configuration exactly. For strokes approaching 300 mm or more, consider an external guide rail to support the extended rod and prevent bending under side loads.
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 SCD32X175 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa, it outputs 345 N in both directions. At the maximum operating pressure of 0.9 MPa, the force is 621 N.
Select the SCD when you need to mount tooling, stops, or sensors on both ends, or when you require perfectly equal speed and force in both directions. A single-rod SC cylinder has a higher push force due to the full piston area but a lower pull force.
