Airtac SCD Standard Cylinder SCD160X350
The AirTAC Airtac SCD Standard Cylinder SCD160X350 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, 350mm stroke, PT3/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD160X350
The SCD160X350 is a double-acting, double-rod pneumatic cylinder that provides perfectly symmetrical force output in both directions, delivering 9425 N at 0.5 MPa and reaching 16964 N at the maximum operating pressure of 0.9 MPa. With a substantial 40 mm diameter rod passing through both end caps, this 160 mm bore cylinder ensures equal push and pull thrust because the rod area is subtracted from the piston on both sides, making it ideal for applications where balanced, two-sided actuation is non-negotiable.
This 350 mm stroke model features a tie-rod construction with a body length (A) of 352 mm and an adjustable air cushion of 29 mm at each end to decelerate the piston smoothly. The PT3/4 port and M36x2 rod thread handle high flow and robust mechanical connections, while the operating speed range of 30-500 mm/s suits heavy, controlled linear movements in industrial automation.
Airtac SCD Standard Cylinder SCD160X350 Technical Specifications

| Stroke | 350 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 SCD160X350 Is Used
Two-Sided Transfer Shuttles
The equal 9425 N force in both directions makes the SCD160X350 perfect for heavy transfer shuttles that must move a pallet or fixture between two stations with identical speed and thrust profiles, using the rear rod for a counterbalance or secondary guide.
Symmetric Pressing & Clamping
Use the through-rod to drive a pressing plate from one end while the opposite rod end actuates a synchronized ejector or stripper mechanism, ensuring a balanced clamping force of up to 16964 N at 0.9 MPa without asymmetric frame loading.
Dual-Side Tooling Actuation
Mount a forming tool on the front rod and a limit-switch dog or secondary tool on the rear rod. The 40 mm through-rod provides superior guidance and anti-rotation, keeping both tools aligned during the full 350 mm stroke under high thrust.
Is the Airtac SCD Standard Cylinder SCD160X350 the Right Cylinder?
Select the SCD160X350 when your application requires identical force and speed in both extend and retract strokes, and the 9425 N output at 0.5 MPa matches your load. If you need more force, step up to the SCD200 bore, which provides 15080 N at the same pressure; for a lighter, more compact solution, the SCD125 bore offers 5734 N. This double-rod cylinder is the right choice over a single-rod SC when you need to mount tooling, a stopper, or a sensor flag on the rear rod, or when the inherent anti-rotation guidance of the through-rod is beneficial.
At a 350 mm stroke, consider the unsupported rod length when the cylinder is extended. While the double-rod design provides better bearing support than a single-rod cylinder, significant side loads should be managed with an external linear guide or by upgrading to a dedicated guided cylinder to prevent rod bending and premature seal wear. For direct replacement, match the 160 mm bore, 350 mm stroke, PT3/4 port thread, and ensure any mounting accessories are from the SCD-compatible FA, LB, or TC series.
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 SCD160X350 FAQ
Because the SCD160X350 is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 9425 N, at 0.7 MPa it produces 13194 N, and at the maximum operating pressure of 0.9 MPa it delivers 16964 N in both directions.
Choose the SCD160 when you need perfectly equal force and speed in both directions, or when you require a rear rod extension to mount sensors, a stroke-adjustment stopper, or secondary tooling. The through-rod also provides better inherent guidance and anti-rotation than a single-rod cylinder, though it is not a replacement for an external guide under high side loads.
