Airtac SCD Standard Cylinder SCD32X15
The AirTAC Airtac SCD Standard Cylinder SCD32X15 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, 15mm stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD32X15
The SCD32X15 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 12 mm rod passing through both end caps. This symmetric actuation makes it ideal for short-stroke tasks where space is tight but balanced motion is critical, such as operating a small two-sided clamp or a precision ejector.
With a 15 mm stroke, this is a non-standard configuration tailored for very short linear movements. The cylinder body measures 187 mm (A dimension) and features PT1/8 ports with an M10x1.25 rod thread. Its adjustable air cushion, with a 21 mm cushion length, provides smooth deceleration at the end of each stroke, protecting the end caps from impact.

| Stroke | 15 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 SCD32X15 Is Used
Two-Sided Clamping
The through rod allows mounting a clamp jaw on each end, providing equal closing force from both sides of the cylinder for symmetrical workpiece holding.
Non-Rotating Guide Bar
The dual-rod support naturally resists piston rotation, making it suitable for a short linear guide where an external rail is not feasible.
Rear Stroke Sensing
The protruding rear rod provides a convenient, clean surface for mounting a sensor flag or cam, enabling end-of-stroke detection without brackets on the main tooling.
Is the Airtac SCD Standard Cylinder SCD32X15 the Right Cylinder?
For applications needing slightly more force in the same compact footprint, stepping up to the SCD40 bore provides 528 N of push and pull at 0.5 MPa. If your task requires force in only one direction, a standard single-rod SC cylinder would be a more economical choice, as it offers a higher push force on the full-bore side. This SCD32X15 is a direct replacement for another AirTAC SCD32 cylinder only if the bore, 15 mm stroke, PT port thread, basic mounting, and lack of a magnet are an exact match.
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 SCD32X15 FAQ
The push and pull forces are equal because the rod extends from both ends. At 0.5 MPa, the force is 345 N in both directions. At the maximum operating pressure of 0.9 MPa, the force increases to 621 N.
A double-rod cylinder like the SCD32X15 is chosen when you need identical force and speed in both directions, or when you need to mount a tool or sensor on the rear rod. The dual-rod design also provides better guidance and resistance to side load than a single-rod cylinder of the same bore.
