Airtac SCD Standard Cylinder SCD160X900S
The AirTAC Airtac SCD Standard Cylinder SCD160X900S 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, 900mm stroke, PT3/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD160X900S
The SCD160X900S is a large-bore double-rod pneumatic cylinder delivering balanced bidirectional force for heavy-duty automation. Because the 40 mm rod passes through both end caps, the effective piston area is identical on each side, producing an equal 9425 N of thrust in both extension and retraction at 0.5 MPa. At the maximum operating pressure of 0.9 MPa, this output climbs to 16964 N, providing consistent power for tooling mounted on either end of the through-rod.
This 900 mm stroke model stays within the standard stroke range for the 160 mm bore, which extends up to 1500 mm. The cylinder body length A(SCD) is 352 mm, and the adjustable air cushion at each end is 29 mm long, helping to decelerate large inertial loads smoothly. A built-in magnet (denoted by the -S suffix) is integrated into the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke detection without external flags.

| 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 SCD160X900S Is Used
Bidirectional Transfer Shuttles
The equal force in both directions makes the SCD160X900S perfect for heavy transfer carts or shuttle tables that must move a pallet forward and then return it with identical speed and power, using the rear rod for a counterbalance or secondary guide.
Dual-Sided Press Tooling
Mount a forming die on the front rod and an ejector mechanism on the rear rod. The symmetric thrust ensures both operations are perfectly synchronized, driven by a single cylinder with a 900 mm stroke for deep-draw or long-press cycles.
Rear-Mounted Stroke Sensing
The built-in magnet allows sensors to be placed on either side of the barrel, but the rear rod extension provides a protected space to mount a sensor flag or a secondary DMSG switch for redundant position verification on long-stroke, safety-critical moves.
Is the Airtac SCD Standard Cylinder SCD160X900S the Right Cylinder?
Select the SCD160X900S when you need a robust 160 mm bore platform with a 900 mm stroke and identical push-pull force. If your load requires less force, stepping down to the 125 mm bore SCD series reduces the balanced output to 5734 N at 0.5 MPa, which may suit lighter tooling. For applications demanding higher thrust, the 200 mm bore SCD provides 15080 N at the same pressure. This double-rod design is ideal when you need to attach tooling or a brake to the rear rod, but if the load is entirely one-sided, a single-rod SC160 cylinder offers a higher push force from the full-bore area. For strokes of this length, ensure the dual-rod assembly is not subjected to high side loads; an external guide rail or a switch to a guided cylinder is necessary to prevent rod bending and premature bearing wear. To replace an existing unit, match the 160 mm bore, 900 mm stroke, PT port thread, basic mounting, and the -S magnet option.
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 SCD160X900S FAQ
The push and pull forces are identical because it is a double-rod cylinder. At 0.5 MPa, the force is 9425 N in both directions. This increases to 13194 N at 0.7 MPa and 16964 N at the maximum operating pressure of 0.9 MPa.
Choose the SCD160X900S when your application requires identical speed and force in both directions, or when you need to mount tooling, a mechanical stop, or a sensor target on the rear rod. A single-rod SC cylinder will provide a higher push force on the extend stroke because it uses the full piston area, but its pull force is significantly lower.
