Airtac SCD Standard Cylinder SCD80X1000TC
The AirTAC Airtac SCD Standard Cylinder SCD80X1000TC 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. Ø80mm bore, 1000mm stroke, PT3/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD80X1000TC
The SCD80X1000TC is a double-acting, double-rod pneumatic cylinder that delivers identical push and pull force—2268 N at 0.5 MPa—because the 25 mm piston rod extends through both end caps. This symmetry eliminates force differentials, making it ideal for applications where a tool or sensor flag is mounted on the rear rod or where balanced thrust is critical. With a 1000 mm stroke and a body length A(SCD) of 257 mm, it provides a long, guided linear motion for transfer and shuttle tasks.
This TC-suffix model includes a centre trunnion pivot mount, allowing the cylinder body to swing as it actuates, which accommodates angular misalignment in the driven load. The trunnion bracket (F-SC80TC) is supplied with the cylinder. It features PT1/8 ports, adjustable pneumatic cushioning over a 28 mm length for smooth deceleration, and operates on 40 µm filtered air from 0.15 to 1.0 MPa.
Airtac SCD Standard Cylinder SCD80X1000TC Technical Specifications

|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø80 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 1000 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT3/8 |
| 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, 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 (Ø80mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 SCD80X1000TC Is Used
Two-Sided Shuttle Tables
The through-rod design allows tooling to be mounted on both ends, enabling a single cylinder to shuttle a workpiece between two stations with perfectly synchronized motion and equal force in each direction.
Symmetric Pusher with Rear Flag
Use the front rod to push a product while the rear rod carries a sensor flag or cam. The equal 4082 N thrust at 0.9 MPa ensures the pusher force is consistent, and the rear rod provides a clean signal for stroke-end detection.
Pivoting Transfer Arm
The centre trunnion mount (TC) lets the entire cylinder pivot, making it perfect for a transfer arm that must lift and swing a part from one conveyor to another without binding, all while maintaining equal power in the lift and return strokes.
Is the Airtac SCD Standard Cylinder SCD80X1000TC the Right Cylinder?
Choose the SCD80 bore when your application needs a balanced 2268 N of force in both directions at 0.5 MPa. If you require more thrust, stepping up to the SCD100 bore provides 3681 N under the same pressure. For applications needing force in only one direction, a single-rod SC80 cylinder offers a higher push force (2513 N at 0.5 MPa) from the full-bore area. This double-rod model is a direct replacement for an existing AirTAC SCD80 cylinder when all five points match: 80 mm bore, 1000 mm stroke, PT port thread, TC centre trunnion mount, and no magnet. At this 1000 mm stroke, the long, unsupported rod is susceptible to bending under side loads; use an external linear guide or switch to a guided cylinder if the load is not perfectly axial.
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 SCD80X1000TC FAQ
Because the piston rod extends from both ends, the effective pressure area is identical for both directions. The force is 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at the maximum operating pressure of 0.9 MPa. The theoretical force at 1.0 MPa is 463 kgf.
Choose the SCD80 when you need equal force and speed in both directions, or when you need to mount a tool, stopper, or sensor on the rear rod. The through-rod also provides better guidance and anti-rotation than a single-rod cylinder. If you only need force in one direction and want a higher push force from the full piston area, the single-rod SC80 is the better choice.
