The AirTAC Airtac SCD Standard Cylinder SCD160X500S 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, 500mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD160X500S is a large-bore double-rod pneumatic cylinder that produces an identical 9425 N of thrust in both directions at 0.5 MPa, rising to 16964 N at the maximum operating pressure of 0.9 MPa. Its 40 mm diameter rod passes through both end caps, creating a symmetric force profile that is ideal for heavy, balanced tooling on both sides of the piston. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for reliable, non-contact position feedback.
With a 500 mm stroke and a body length A(SCD) of 352 mm, this cylinder provides substantial reach while the adjustable air cushion on each end decelerates large inertial loads over a 29 mm stroke. The PT3/4 port supplies ample flow for the 160 mm bore, and the M36x2 rod threads offer a robust connection for attachments. This configuration is a genuine AirTAC unit, factory-assembled and tested for consistent performance in demanding industrial sequences.

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.

Operates pressing or clamping tools on both ends of the cylinder simultaneously with an equal 16964 N force at 0.9 MPa, perfect for symmetrical assembly jigs.
Drives a heavy transfer cart back and forth with identical speed and force in each direction, using the rear rod to mount a secondary guide or sensor flag.
Applies a precise, equal pull force from both rod ends for material straightening or web tensioning, with the built-in magnet signaling stroke completion.
Select the SCD160X500S when your application requires equal, high-force actuation from both ends of the piston rod. If the 9425 N force at 0.5 MPa is more than needed, stepping down to an SCD125 bore reduces the force to 5734 N at the same pressure. For applications that only need a single working end, a single-rod SC160 cylinder would be a more compact and cost-effective choice. As a direct replacement, match the 160 mm bore, 500 mm stroke, PT3/4 port, basic mounting, and the integrated magnet (-S) suffix to ensure a drop-in fit for an existing AirTAC SCD double-rod unit.
At this 500 mm stroke length, the unsupported portion of the 40 mm rod can be subject to bending under high side loads. If your tooling applies a significant radial force, do not rely on the rod's guidance alone; instead, couple the cylinder with an external linear guide rail or consider a purpose-built guided cylinder to protect the rod bearings and ensure long service life.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it outputs 9425 N, at 0.7 MPa it is 13194 N, and at the maximum operating pressure of 0.9 MPa it reaches 16964 N in both directions.
Choose the SCD when you need to mount tooling, a stopper, or a sensor flag on the rear rod, or when you require perfectly equal force and speed in both directions. The through-rod design also provides better support for the piston, reducing uneven bushing wear compared to a single-rod cylinder under frequent cycling.
