Airtac SCD Standard Cylinder SCD160X350S
The AirTAC Airtac SCD Standard Cylinder SCD160X350S 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 SCD160X350S
The SCD160X350S is a double-acting, double-rod pneumatic cylinder that outputs an identical 9425 N of force in both directions at 0.5 MPa, thanks to its 40 mm through-rod subtracting the same area on each side. This symmetry is ideal for tooling mounted on both ends or applications requiring a rear rod for stroke confirmation flags.
With a 350 mm stroke, this tie-rod cylinder stays within the standard range for its 160 mm bore. The adjustable air cushion (29 mm length) decelerates the piston smoothly at end-of-travel, while the built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for contactless position sensing.
Airtac SCD Standard Cylinder SCD160X350S Technical Specifications

| Bore size | Ø160 mm |
| Rod diameter | Ø40 mm (both ends) |
| 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 SCD160X350S Is Used
Two-Sided Transfer Shuttle
The equal push/pull force of 9425 N at 0.5 MPa makes this cylinder perfect for shuttling heavy pallets or components between two stations, with tooling attached to both rod ends for balanced, synchronized motion.
Rear-Mounted Stroke Sensing
The through-rod at the rear cap provides a perfect mounting point for a sensor flag or cam. Combined with the built-in magnet (-S) and barrel-mounted sensors, you get redundant, high-confidence end-of-stroke detection for critical processes.
Heavy-Duty Symmetric Clamping
Delivering 16964 N of clamping force at the maximum operating pressure of 0.9 MPa, the SCD160X350S can drive a two-sided clamp or press fixture where the force must be identical from both directions to prevent part distortion.
Is the Airtac SCD Standard Cylinder SCD160X350S the Right Cylinder?
Choose the SCD160 bore when your application needs roughly 9425 N of balanced thrust at 0.5 MPa. If you require more force, stepping up to the SCD200 delivers 15080 N at the same pressure. For tasks that only need push force and have no use for a rear rod, the single-rod SC160 is a lighter and more compact alternative. The through-rod provides better guidance than a single-rod cylinder, but it is not a guided cylinder; for significant side loads, use an external guide rail.
When replacing an existing unit, match five points: 160 mm bore, 350 mm stroke, PT port thread, the specific SCD mounting accessory (this model is basic, so no bracket is included), and the -S magnet option for sensor compatibility. The 350 mm stroke length is well-supported, but always ensure the rod is not subjected to bending moments from misaligned loads.
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 SCD160X350S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. 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 produces 16964 N. The theoretical force at 1.0 MPa is 1922 kgf.
Choose the SCD when you need identical force and speed in both directions, or when you need to mount tooling, a stopper, or a sensor flag on the rear rod. The through-rod also provides better bearing support and some resistance to rotation compared to a single-rod cylinder, making it suitable for applications where the rod must not twist.
