The AirTAC Airtac SCD Standard Cylinder SCD160X700 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, 700mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD160X700 is a large-bore double-rod pneumatic cylinder that outputs an identical 9425 N of thrust in both extend and retract directions at 0.5 MPa, thanks to its through-rod construction. With a 40 mm diameter rod protruding from both end caps and a 29 mm adjustable air cushion, it provides symmetric force and controlled deceleration for heavy, balanced tooling on each side of the piston.
This 160 mm bore tie-rod cylinder has a body length (A) of 352 mm and operates on filtered air from 0.15 to 1.0 MPa. At the maximum operating pressure of 0.9 MPa, it generates 16964 N of force in either direction, making it a robust choice for large-scale industrial transfer mechanisms that require identical push and pull capability.

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.
| 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.

The equal 9425 N force in both directions makes the SCD160X700 ideal for large transfer shuttles that pick and place tooling on both ends of the through-rod, ensuring perfectly synchronized motion.
With a 40 mm rod extending from both ends, the dual-rod support provides inherent anti-rotation for wide pusher plates, eliminating the need for an external guide in purely axial, low-side-load applications.
The rear rod extension offers a convenient, clean mounting point for stroke adjustment stops, external shock absorbers, or a sensor flag bracket, keeping the main tooling side clear and accessible.
Choose the SCD160 when your application demands balanced, high-force actuation from both ends of the piston rod, such as driving a large shuttle table. If your load requires less force, stepping down to the SCD125 provides 5734 N at 0.5 MPa, while a step up to the SCD200 offers 15080 N. For a 700 mm stroke, ensure the rod is adequately supported against bending under compressive load; an external guide rail or a switch to a guided cylinder is recommended if significant side forces are present.
This is a direct replacement for an existing AirTAC SCD160 cylinder, provided the bore, 700 mm stroke, PT port thread, and basic mounting style all match. If your current unit has a magnet for sensors, order the -S variant.
Double-rod checklist
Because it 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 produces 16964 N in both directions.
Select the SCD when you need identical force and speed in both directions, or when you require a rear rod extension to mount tooling, a mechanical stop, or a sensor flag. The dual-rod bearing also offers better guidance and anti-rotation than a single-rod SC, but it is not a substitute for a fully guided cylinder under heavy side loads.
