Airtac SCD Standard Cylinder SCD160X300
The AirTAC Airtac SCD Standard Cylinder SCD160X300 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø40mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø160mm bore, 300mm stroke, PT3/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD160X300
The SCD160X300 is a double-acting, double-rod pneumatic cylinder that provides identical thrust in both directions—9425 N at 0.5 MPa—because the 40 mm rod passes through both end caps. This symmetry eliminates force differentials, making it ideal for applications where a tool or sensor must be mounted on the rear rod end, or where balanced, repeatable motion is required in both extend and retract.
With a 300 mm stroke and a body length A of 352 mm, this 160 mm bore cylinder uses PT3/4 ports and an M36x2 rod thread. The adjustable air cushion (29 mm) decelerates the piston at each end of travel. It operates on 40 µm filtered air from 0.15 to 1.0 MPa and supports speeds of 30-500 mm/s, fitting heavy-duty transfer and lifting tasks where a through-rod design adds guidance and anti-rotation stability.
Airtac SCD Standard Cylinder SCD160X300 Technical Specifications

| Bore size | Ø160 mm |
| Rod diameter | Ø40 mm (both ends) |
| Stroke | 300 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT3/4 |
| Rod thread | M36×2 |
| 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 – 500 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 (Ø160mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | 13195 N |
| Max (@1.0 MPa) | 1922 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 SCD160X300 Is Used
Two-Sided Actuation
The rear rod extension allows a second tool or a counterbalance weight to be attached, enabling simultaneous work on both sides of the cylinder with perfectly synchronized, equal force.
Heavy Shuttle Tables
Delivers 9425 N of balanced thrust in both directions to move heavy pallets or fixtures on a transfer line, with the rear rod available for mounting a stroke sensor flag.
Symmetric Pressing & Straightening
The equal push-pull force and improved rod guidance from the double-rod design suit light straightening or pressing fixtures where the load must be engaged from both ends.
Is the Airtac SCD Standard Cylinder SCD160X300 the Right Cylinder?
Choose the SCD160 when your application needs balanced, two-sided force around 9425 N at standard plant pressure. If you require more thrust, step up to the SCD200, which provides 15080 N at 0.5 MPa. For purely single-sided pushing, a single-rod SC160 cylinder offers a higher push force (10053 N at 0.5 MPa) due to the full piston area on the blind side. This double-rod model is a direct replacement for another AirTAC SCD160 of matching bore, stroke, PT port thread, and basic mounting; it is not dimensionally interchangeable with ISO 15552 cylinders. At a 300 mm stroke, ensure the load is guided externally to prevent rod bending, as the through-rod provides better support than a single rod but is not a substitute for a dedicated guided cylinder under side load.
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 SCD160X300 FAQ
Push and pull forces are identical on this double-rod cylinder. At 0.5 MPa it outputs 9425 N, at 0.7 MPa it is 13194 N, and at the maximum operating pressure of 0.9 MPa it reaches 16964 N. The theoretical force at 1.0 MPa is 1922 kgf.
Choose the SCD when you need equal force and speed in both directions, or when you need to mount a tool, bracket, or sensor on the rear rod. The through-rod also provides better bearing support than a single-rod SC, reducing rod deflection. If you only need a strong push stroke and the retract force is less critical, the single-rod SC160 will be more cost-effective.
