Airtac SCD Standard Cylinder SCD32X100S
The AirTAC Airtac SCD Standard Cylinder SCD32X100S 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, 100mm stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD32X100S
The SCD32X100S is a compact double-rod pneumatic cylinder that outputs an identical 345 N of force in both extend and retract directions at 0.5 MPa, thanks to its through-rod design. The 12 mm rod passes through both end caps, providing a rear connection point for a sensor flag or secondary tooling while naturally resisting rotation better than a single-rod unit.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. With a 100 mm stroke and PT1/8 ports, it fits neatly into compact two-sided actuation tasks where space is tight and the load must be moved equally in both directions.
Airtac SCD Standard Cylinder SCD32X100S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD32X100S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø32 mm |
| Rod diameter | Ø12 mm (both ends) |
| Stroke | 100 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 SCD32X100S Is Used
Two-Sided Fixture Actuation
The rod extending from both ends can push a part into a fixture while the rear rod triggers a limit switch, ensuring a complete cycle every time with balanced force.
Non-Rotating Precision Pusher
The dual-rod support provides inherent anti-rotation for a small pusher plate, maintaining alignment on a 100 mm stroke without needing an external guide rail.
Sensor-Ready Stroke Verification
The built-in magnet lets you mount CMSG/DMSG sensors directly on the cylinder body to confirm end-of-stroke positions, simplifying electrical integration.
Is the Airtac SCD Standard Cylinder SCD32X100S the Right Cylinder?
Choose the SCD32 when your application needs balanced bidirectional force in a small footprint. If you require more thrust, the next step up is the SCD40, which provides 528 N at the same 0.5 MPa. For tasks that only need a strong push stroke and a weaker pull, the single-rod SC32 is a simpler and more cost-effective choice. Always ensure the external guide or load is aligned, as the dual-rod design improves guidance but does not eliminate the need for external support under side loads.
To replace an existing SCD32X100S, match the 32 mm bore, 100 mm stroke, PT port thread, basic mounting, and the integrated magnet feature. This is a genuine AirTAC double-rod cylinder, designed as a direct dimensional and functional replacement for the same model.
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 SCD32X100S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. 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 delivers 621 N in both directions.
You choose an SCD when you need identical force and speed in both directions, or when you need to attach a tool, stopper, or sensor flag to the rear rod. The through-rod also provides better support for the piston, reducing uneven wear compared to a single-rod cylinder in certain applications.
