Airtac SCD Standard Cylinder SCD32X50S
The AirTAC Airtac SCD Standard Cylinder SCD32X50S 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, 50mm stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD32X50S
The SCD32X50S is a compact double-rod pneumatic cylinder that outputs an identical 345 N of force in both directions at 0.5 MPa, thanks to its through-rod design. With a 12 mm rod extending from both end caps and a 50 mm stroke, it is ideal for light-duty tasks where a rear rod connection point or symmetric thrust is needed.
This model includes a factory-installed magnet, allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. The body length A(SCD) is 187 mm, and the adjustable air cushion (21 mm) at each end helps manage end-of-stroke deceleration quietly.

|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø32 mm |
| Rod diameter | Ø12 mm (both ends) |
| Stroke | 50 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 SCD32X50S Is Used
Two-Sided Reciprocating Fixtures
The equal push/pull force of 345 N at 0.5 MPa makes this cylinder perfect for small clamps or test fixtures that must apply the same pressure from either direction.
Sensor-Monitored Actuation
With the built-in -S magnet, you can mount reed or solid-state sensors directly on the barrel to confirm end-of-stroke position, ideal for pick-and-place verification.
Anti-Rotation Linear Guides
The dual 12 mm rods provide better resistance to rotation than a single-rod cylinder, useful for keeping a small tooling plate aligned without adding an external guide rail.
Is the Airtac SCD Standard Cylinder SCD32X50S the Right Cylinder?
Choose the SCD32 when your application requires equal push and pull force of 345 N at 0.5 MPa. If you need more thrust, stepping up to the SCD40 delivers 528 N at the same pressure. This double-rod unit is the right pick when you need to mount tooling or a sensor flag on the rear rod; if you only need force from one end, the single-rod SC32 series is a simpler, more compact alternative. For a direct replacement, match the 32 mm bore, 50 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 SCD32X50S FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. 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 reaches 621 N.
Choose the SCD32 when you need the piston rod to do work on both ends of the cylinder, require perfectly equal force and speed in both directions, or want the improved bearing support and anti-rotation guidance that a through-rod provides.
