Airtac SCD Standard Cylinder SCD160X75
The AirTAC Airtac SCD Standard Cylinder SCD160X75 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, 75mm stroke, PT3/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD160X75
The SCD160X75 is a double-acting, double-rod pneumatic cylinder that produces identical force in both directions—9425 N at 0.5 MPa—because the 40 mm rod passes through both end caps. This symmetrical output makes it ideal for applications where a rear rod connection is needed for a sensor flag, stopper bolt, or secondary tooling, ensuring consistent motion regardless of direction.
With a 75 mm stroke and a body length A(SCD) of 352 mm, this model fits compact transfer and lifting stations. The adjustable air cushion at each end (29 mm length) decelerates the piston smoothly, while the PT3/4 ports supply ample flow for the 160 mm bore. The through rod also improves bearing support compared to a single-rod cylinder, helping to resist slight rotational forces without adding external guides.
Airtac SCD Standard Cylinder SCD160X75 Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD160X75 |

| Series | SCD double-rod tie-rod cylinder (ISO 6430 class) |
| Bore size | Ø160 mm |
| Rod diameter | Ø40 mm (both ends) |
| Stroke | 75 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 SCD160X75 Is Used
Two-Sided Actuation
The rear rod extension can push a secondary mechanism or operate a limit switch, synchronizing two actions with one cylinder and ensuring equal force on both ends.
Shuttle Transfer Tables
Moves a pallet or fixture between two positions with identical speed and thrust in each direction, using the rear rod to trigger a confirmation sensor for cycle completion.
Non-Rotating Pusher
The dual-rod design inherently resists piston rotation, making it suitable for pushing loads that must not twist, such as a panel into a press or an alignment jig.
Is the Airtac SCD Standard Cylinder SCD160X75 the Right Cylinder?
Choose this 160 mm bore when your application needs roughly 9425 N of balanced force at standard plant pressure. If your load is lighter, stepping down to the SCD125 bore (5734 N at 0.5 MPa) can reduce air consumption and physical size. For applications requiring a stroke longer than the standard 1500 mm maximum, a non-standard order is necessary.
This SCD double-rod unit is the correct choice over a single-rod SC when you need a rear rod extension for mounting cams or sensors, or when you want equal speed and force in both directions. Be aware that a through rod provides better guidance than a single rod, but it is not a guided cylinder; for significant side loads, pair it with an external linear guide. To replace an existing SCD160X75, match the 160 mm bore, 75 mm stroke, PT3/4 port thread, basic mounting, and confirm if a magnet is needed.
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 SCD160X75 FAQ
Because it is a double-rod cylinder, push and pull forces are identical. At 0.5 MPa it outputs 9425 N, at 0.7 MPa it outputs 13194 N, and at the maximum operating pressure of 0.9 MPa it delivers 16964 N.
Choose the SCD when you need a rod protruding from both ends to mount tooling on both sides, to attach a rear sensor flag, or to achieve perfectly equal force and speed in both directions. A single-rod SC has a higher push force for the same bore but unequal pull force, and no rear rod access.
