Airtac SCD Standard Cylinder SCD32X50
The AirTAC Airtac SCD Standard Cylinder SCD32X50 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 SCD32X50
The SCD32X50 is a compact double-rod pneumatic cylinder that provides an identical 345 N of force in both directions at 0.5 MPa, thanks to its 12 mm rod passing through both end caps. This 50 mm stroke unit is built for applications where you need to mount tooling or a sensor flag on the rear rod, or simply require perfectly symmetrical actuation.
With a body length A(SCD) of 187 mm and an adjustable air cushion of 21 mm, it decelerates the piston smoothly at each end. The PT1/8 ports and M10x1.25 rod threads are standard, and the tie-rod construction keeps it serviceable. This model is a genuine AirTAC unit, ready for dual-sided tasks.

| 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 SCD32X50 Is Used
Reciprocating Transfer
The equal force in both directions makes the SCD32X50 ideal for small part shuttles where a consistent push and pull stroke is required to move a fixture back and forth.
Dual-Sided Sensing
Use the rear 12 mm rod extension to mount a sensor flag or cam, enabling end-of-stroke detection on the back of the cylinder without interfering with the primary tooling on the front rod.
Anti-Rotation Guide
The through-rod design provides inherent anti-rotation stability for light-duty pressing or aligning tasks, keeping the tooling orientation consistent without an external guide rail.
Is the Airtac SCD Standard Cylinder SCD32X50 the Right Cylinder?
Choose the SCD32X50 when your mechanism needs equal push and pull force from both ends of the cylinder. If you need more thrust, stepping up to the SCD40 bore provides 528 N at the same 0.5 MPa pressure. For a simpler, single-sided actuation, the single-rod SC32 series is a more cost-effective choice. This double-rod design offers better rod guidance than a single rod but is not a substitute for a fully guided cylinder under significant side loads. For a drop-in replacement, match the 32 mm bore, 50 mm stroke, PT port thread, basic mounting, and absence of a magnet.
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 SCD32X50 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it outputs 345 N, at 0.7 MPa it's 483 N, and at the maximum operating pressure of 0.9 MPa, it delivers 621 N in both directions.
Choose the SCD32 when you need to mount tooling or sensors on both ends of the piston rod, require perfectly equal force and speed in both directions, or need the extra rod guidance to prevent rotation. If you only need to push from one side, the single-rod SC32 is a simpler and more economical option.
