The AirTAC Airtac SCD Standard Cylinder SCD160X175 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, 175mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD160X175 is a double-acting pneumatic cylinder with a through-rod design, delivering identical force in both directions—9425 N at 0.5 MPa and up to 16964 N at the maximum operating pressure of 0.9 MPa. Its 40 mm diameter rod extends from both ends, providing a symmetric actuation platform ideal for tasks where tooling or sensors must be mounted on the rear rod, or where equal speed and thrust are critical for process control. The 175 mm stroke operates within the standard range for this 160 mm bore, and the body length A(SCD) is 352 mm.
This tie-rod cylinder uses a PT3/4 port and features an adjustable air cushion (29 mm length) at both ends to decelerate the piston mass smoothly. The SCD160 series is built for robust, repetitive tasks like operating two opposing fixtures simultaneously or driving a transfer mechanism with a guided rear linkage. For position sensing, a magnet can be added by ordering the -S suffix, allowing CMSG or DMSG sensors to clamp directly onto the barrel.

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 push/pull force of 9425 N at 0.5 MPa makes the SCD160X175 perfect for clamping two workpieces simultaneously from opposite sides, ensuring uniform pressure without complex linkage.
Use the rear rod to mount a sensor flag or a secondary stopper. The through-rod design provides inherent anti-rotation, keeping a transfer shuttle aligned over the 175 mm stroke without twisting.
Drive a tool on the front rod and a counterbalance or return spring on the rear rod. The symmetric force output ensures consistent motion profiles for both sides of the machine cycle.
Choose the SCD160X175 when your application requires balanced, high-force actuation from both sides of the piston. If your force requirement is lower, stepping down to the SCD125 bore reduces the output to 5734 N at 0.5 MPa, saving energy and physical space. For applications needing even higher thrust, the SCD200 bore provides 15080 N at the same pressure. This double-rod unit is ideal for pushing and pulling a load with equal force, but if you only need to actuate from one end, a single-rod SC series cylinder is a more economical choice. For direct replacement, match the 160 mm bore, 175 mm stroke, PT3/4 port thread, and ensure any mounting accessories like FA or LB brackets are also specified.
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.
Choose the SCD160X175 when you need to mount tooling or sensors on both ends of the rod, require perfectly equal speed and force for push and pull strokes, or need the enhanced bearing support a through-rod provides to resist deflection. If you only need force applied from one end, the single-rod SC160 is a more cost-effective alternative.
