Airtac SCD Standard Cylinder SCD63X100H
The AirTAC Airtac SCD Standard Cylinder SCD63X100H 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 SCD63X100H
The SCD63X100H is a double-acting, double-rod pneumatic cylinder equipped with high-temperature Viton (FKM) seals, extending its operating range to 0–150 °C. With a 63 mm bore and a 20 mm through-rod, it generates an identical 1402 N of thrust in both directions at 0.5 MPa, making it a strong choice for hot-environment tooling that needs symmetric force.
This 100 mm stroke model features a body length A(SCD) of 210 mm and an adjustable air cushion of 28 mm at each end. The rod protrudes from both caps, giving you a rear rod end for mounting a sensor flag or secondary tooling, while the Viton seals ensure reliable sealing life in high-temperature or chemically aggressive surroundings.

| 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 SCD63X100H Is Used
High-Temperature Two-Sided Actuation
Operates reliably in ambient temperatures up to 150 °C thanks to Viton seals. The double-rod design delivers equal push-pull force for hot presses, drying ovens, or foundry tooling where a single-rod cylinder's seals would degrade prematurely.
Symmetric Transfer Shuttles
The 20 mm through-rod provides identical acceleration and deceleration in both stroke directions. Ideal for a 100 mm transfer shuttle that must move a part carrier left and right with the same cycle time and stopping precision.
Rear-Mounted Stroke Sensing
With the rod extending from the rear cap, you can mount a sensor flag or limit switch actuator on the back side. This keeps the front tooling area clear while enabling full-stroke confirmation in a compact 100 mm stroke envelope.
Is the Airtac SCD Standard Cylinder SCD63X100H the Right Cylinder?
Select the SCD63X100H when your application demands equal push and pull output at elevated temperatures. If 1402 N at 0.5 MPa is insufficient, stepping up to the SCD80 bore provides 2268 N; if it is excessive, the SCD50 bore offers 825 N. For single-direction work, a single-rod SC cylinder may be a simpler, lower-cost alternative.
To replace an existing unit, match the 63 mm bore, 100 mm stroke, PT port thread, basic mounting, and the Viton seal designation. The SCD family does not include FB flange or CA/CB clevis mounts—use FA, LB, or TC centre trunnion if a bracket is needed. This cylinder does not lock a load when air pressure is removed; if position holding is required, add an external rod brake or pilot-operated check valve.
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 SCD63X100H FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 1402 N, at 0.7 MPa it produces 1962 N, and at the maximum operating pressure of 0.9 MPa it delivers 2523 N in both directions.
Choose the SCD when you need equal force and speed in both directions, or when you require a rear rod extension for mounting sensors, stoppers, or secondary tooling. The through-rod also provides better guidance and inherent anti-rotation compared to a single-rod cylinder, though it is not a substitute for a fully guided unit under heavy side loads.
