Airtac SCD Standard Cylinder SCD63X100S
The AirTAC Airtac SCD Standard Cylinder SCD63X100S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 100mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD63X100S
The SCD63X100S is a double-acting, double-rod pneumatic cylinder delivering identical force in both directions—1402 N at 0.5 MPa—thanks to its through-rod design that subtracts the same Ø20 mm rod area from each side. This 100 mm stroke unit includes a built-in magnet, so CMSG, DMSG, or EMSG sensors clip directly onto the tie-rod barrel for non-contact end-of-stroke detection without extra brackets.
With a 28 mm adjustable air cushion at each end and a retracted body length A of 210 mm, the cylinder decelerates the piston smoothly, protecting end caps during high-cycle operation. The rear rod extension is ideal for mounting a secondary tool, stopper, or a sensor flag, making it a compact solution for tasks that need actuation or feedback from both ends of the cylinder.
Airtac SCD Standard Cylinder SCD63X100S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD63X100S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø63 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 100 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 28 mm |
| Max stroke | Up to 1500 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 (Ø63mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 SCD63X100S Is Used
Two-Sided Actuation
With a rod extending from both ends, this cylinder can push a workpiece on the forward stroke and pull a return mechanism on the rear stroke simultaneously, simplifying transfer station design.
Rear Stroke Sensing
The built-in magnet works with barrel-mounted sensors on either end, but the rear rod provides a perfect mounting point for a secondary sensor flag, enabling redundant position verification in safety-critical pick-and-place cells.
Symmetric Tooling Loads
The through-rod design balances bearing loads better than a single-rod cylinder, reducing uneven wear when the tooling plate is guided externally, which is common in light pressing or stamping fixtures.
Is the Airtac SCD Standard Cylinder SCD63X100S the Right Cylinder?
Choose the SCD63 bore when your application needs about 1400 N of force each way at standard plant pressure. If you can accept slightly less force and a smaller footprint, the SCD50 delivers 825 N at 0.5 MPa. For a step up, the SCD80 provides 2268 N. This double-rod unit is the right pick when you need equal push-pull thrust and a rear rod; if you only need force from one end, the single-rod SC63 series is lighter and more compact. For direct replacement, match the 63 mm bore, 100 mm stroke, PT ports, basic mounting, and the -S magnet option. The 100 mm stroke is well within standard limits, so rod bending is not a concern here.
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 SCD63X100S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. At 0.5 MPa you get 1402 N, at 0.7 MPa it is 1962 N, and at the maximum operating pressure of 0.9 MPa it reaches 2523 N in both directions.
You would choose the SCD when you need identical force and speed in both directions, or when you need the rear rod extension to mount a second tool, a mechanical stop, or a position sensor flag. The dual-rod support also provides better guidance for the piston, though it is not a substitute for an external guide under high side loads.
