Airtac SCD Standard Cylinder SCD100X350LB
The AirTAC Airtac SCD Standard Cylinder SCD100X350LB 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, 350mm stroke, PT1/2 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD100X350LB
The SCD100X350LB is a double-acting, double-rod pneumatic cylinder where the 25 mm piston rod extends from both ends, guaranteeing identical push and pull force of 3681 N at 0.5 MPa. Its 350 mm stroke is well within the 1500 mm maximum for the 100 mm bore, and the adjustable air cushion on each end cap (29 mm length) smoothly decelerates the piston near stroke end.
This model comes configured with an LB foot mount (F-SC100LB) for stable surface mounting, and the standard TPU seals with PT ports. The through-rod design provides inherent anti-rotation and allows you to mount tooling, a rear stroke sensor flag, or a secondary actuator on the back side, making it a versatile choice for transfer and shuttle applications.
Airtac SCD Standard Cylinder SCD100X350LB Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD100X350LB |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø100 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 350 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 SCD100X350LB Is Used
Bi-Directional Transfer Shuttles
The equal force and speed in both directions make this cylinder ideal for shuttle tables that move parts between two stations, ensuring consistent cycle times regardless of travel direction.
Non-Rotating Pusher Stations
With a rod on both ends, the SCD100X350LB resists piston rotation better than a single-rod cylinder, useful for pusher applications where maintaining tooling alignment over a 350 mm stroke is critical.
Dual-Sided Actuation & Sensing
The rear rod extension provides a convenient mounting point for a stroke sensor flag or a secondary tool, enabling end-of-stroke confirmation or a tandem actuation sequence from one cylinder body.
Is the Airtac SCD Standard Cylinder SCD100X350LB the Right Cylinder?
Choose the SCD100 when your application needs 3681 N of force in both directions at 0.5 MPa. If your load is lighter, stepping down to the SCD80 bore reduces force to 2268 N and may lower air consumption. For heavier loads, the SCD125 bore offers 5734 N. Because this is a 350 mm stroke, ensure the long, unsupported rod is not exposed to significant side loads; if side forces are present, an external guide rail or a dedicated guided cylinder is a safer choice than relying solely on the double-rod bearings.
This SCD100X350LB is a direct replacement for an existing AirTAC SCD cylinder of the same 100 mm bore, 350 mm stroke, PT port thread, and LB foot mounting configuration. For a full match, also confirm the original's magnet option; this unit has no built-in magnet.
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 SCD100X350LB FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. The force is 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at the maximum operating pressure of 0.9 MPa. The theoretical force at 1.0 MPa is 751 kgf.
Choose the SCD when you need identical push and pull force and speed, or when you need to attach tooling or a sensor to a rod on both ends of the cylinder. The through-rod also provides better guidance and anti-rotation than a single-rod SC, though it is not a substitute for a fully guided cylinder under high side loads.
