Airtac SCD Standard Cylinder SCD100X600
The AirTAC Airtac SCD Standard Cylinder SCD100X600 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø100mm bore, 600mm stroke, PT1/2 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD100X600
The SCD100X600 is a double-acting, double-rod pneumatic cylinder that provides perfectly symmetrical force in both directions, delivering 3681 N of thrust each way at 0.5 MPa. With a 100 mm bore and a 25 mm through-rod extending from both end caps, it eliminates the force imbalance common in single-rod designs, making it ideal for applications where consistent speed and power are critical across the full 600 mm stroke.
This model features a body length A(SCD) of 263 mm and an adjustable air cushion of 29 mm at each end to decelerate the piston smoothly. The PT1/2 port and M20x1.5 rod thread handle high flow, and at the maximum operating pressure of 0.9 MPa, it generates a substantial 6626 N of thrust. It is built for demanding dual-sided tooling or transfer tasks requiring a rear rod for mounting sensors or stoppers.
Airtac SCD Standard Cylinder SCD100X600 Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD100X600 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø100 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 600 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 29 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 (Ø100mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | 5154 N |
| Max (@1.0 MPa) | 751 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 SCD100X600 Is Used
Dual-Sided Transfer Shuttle
The equal 3681 N force in both directions makes this cylinder perfect for shuttle tables that move a fixture or pallet between two stations with identical acceleration and deceleration profiles.
Rear-Mounted Stroke Sensing
Utilize the rear rod extension to mount a sensor flag or cam for end-of-stroke detection, keeping the front tooling area clear and simplifying wiring on automated lines.
Synchronous Material Pusher
Deploy the SCD100X600 as a pusher where the through-rod drives a secondary mechanism or counterbalance, ensuring the pushing force and retraction speed remain perfectly matched.
Is the Airtac SCD Standard Cylinder SCD100X600 the Right Cylinder?
When sizing, the SCD100X600 sits between the SCD80 (2268 N at 0.5 MPa) and the SCD125 (5734 N at 0.5 MPa). If your load requires more force than this model's 3681 N, stepping up to the 125 mm bore is the logical path; for a lighter, more compact solution, the 80 mm bore may suffice. Always confirm that the 600 mm stroke does not expose the unsupported rod to excessive side loads—if lateral forces are present, an external guide rail or a dedicated guided cylinder is a safer choice than relying solely on the dual-rod bearing support.
For a direct replacement, match the 100 mm bore, 600 mm stroke, PT port thread, and basic mounting configuration. If your existing unit uses a magnet for sensors, specify the -S suffix. This SCD model is not dimensionally interchangeable with ISO 15552 cylinders; it is a tie-rod design that replaces another AirTAC SCD of the same specifications.
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 SCD100X600 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it outputs 3681 N, at 0.7 MPa it reaches 5153 N, and at the maximum operating pressure of 0.9 MPa it delivers 6626 N in both directions.
Choose the SCD when you need perfectly equal force and speed in both directions, or when you require a rear rod extension to mount tooling, a brake, or position sensors. The through-rod also provides better guidance and anti-rotation than a single-rod cylinder, though it is not a substitute for an external guide under heavy side loads.
