Airtac SCD Standard Cylinder SCD80X1500
The AirTAC Airtac SCD Standard Cylinder SCD80X1500 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, 1500mm stroke, PT3/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD80X1500
The SCD80X1500 is a double-acting, double-rod pneumatic cylinder that produces an identical 2268 N of thrust in both directions at 0.5 MPa, owing to its 25 mm through-rod subtracting the same area from each piston face. At the maximum operating pressure of 0.9 MPa, output rises to 4082 N, giving this 80 mm bore actuator the muscle for long-stroke transfer and dual-sided tooling tasks.
With a full 1500 mm stroke and a body length A of 257 mm, the cylinder's rod protrudes from both end caps, providing a rear connection point for a stopper bolt, sensor flag, or secondary tool plate. The adjustable air cushion on each end, with a 28 mm cushion length, decelerates the piston smoothly, while the PT3/8 ports and M20x1.5 rod threads keep it compatible with standard AirTAC SCD-series mounting accessories.

|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø80 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 1500 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 SCD80X1500 Is Used
Bidirectional Shuttle Tables
The equal push and pull force of 2268 N at 0.5 MPa makes the SCD80X1500 ideal for driving a shuttle or transfer table back and forth with symmetrical speed and power, simplifying flow-control tuning.
Rear-Mounted Stroke Sensing
The rear piston rod extension provides a perfect, rigid mounting point for a sensor flag or cam, allowing you to install position sensors on the back of the machine without interfering with the primary tooling on the front rod.
Dual-Sided Assembly Fixtures
Attach a press tool to the front rod and a counter-support or ejector to the rear rod. The through-rod design ensures both tools move in perfect synchronization, driven by a single, balanced 4082 N force at 0.9 MPa.
Is the Airtac SCD Standard Cylinder SCD80X1500 the Right Cylinder?
This 80 mm bore SCD suits applications needing balanced bidirectional force around 2268 N at standard plant pressure. If your load requires a step up in force, the SCD100 series delivers 3681 N at the same 0.5 MPa; for a more compact, lighter solution, the SCD63 provides 1402 N. Because the rod extends 1500 mm on both ends, consider the unsupported rod column strength—if side forces are present, an external guide rail or a dedicated guided cylinder is a safer choice than relying on the double-rod bearings alone.
For a direct replacement, match the 80 mm bore, 1500 mm stroke, PT3/8 port thread, and your specific mounting accessory (such as the FA front flange or TC centre trunnion). Adding the -S magnet option allows you to use CMSG/DMSG sensors for end-of-stroke detection. This cylinder is not a drop-in for ISO 15552 dimensions; it replaces another AirTAC SCD80 double-rod unit with the same configuration.
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 SCD80X1500 FAQ
Because it is a double-rod cylinder, the push and pull forces are absolutely equal. At 0.5 MPa it produces 2268 N, at 0.7 MPa it outputs 3175 N, and at the maximum operating pressure of 0.9 MPa the force reaches 4082 N in both directions.
Choose the SCD80 when you need identical force and speed in both directions, or when you require a second rod end for mounting a sensor flag, a mechanical stop, or secondary tooling. The double-rod design also provides better bearing support for the rod, reducing deflection compared to a single-rod cylinder under the same load, though it is not a substitute for an externally guided unit under high side loads.
