The AirTAC Airtac SCD Standard Cylinder SCD63X192S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 192mm stroke, PT1/4 ports and adjustable end cushioning.
The SCD63X192S is a double-acting, double-rod pneumatic cylinder where the piston rod extends from both ends, delivering perfectly balanced 1402 N of force in each direction at 0.5 MPa. This symmetry is ideal for applications requiring identical push and pull thrust, such as two-sided tooling or transfer mechanisms. The 20 mm diameter rod passes through both end caps, providing enhanced guidance and inherent anti-rotation compared to a single-rod design.
This model includes a built-in magnet, denoted by the 'S' suffix, allowing for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise, non-contact position sensing. With a 192 mm stroke and a body length A of 210 mm, it features an adjustable pneumatic cushion (28 mm) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact.

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 | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 through-rod design provides equal force and speed in both directions, making it perfect for simultaneously operating tooling or clamps on opposite sides of a fixture from a single cylinder.
With a rod supported by bearings at both ends, the SCD63X192S offers inherent anti-rotation, ideal for push/pull applications where maintaining the orientation of the attached tooling is critical.
The built-in magnet and exposed rear rod allow for mounting position-sensing flags or directly attaching sensors to the barrel, providing reliable end-of-stroke confirmation from the back of the cylinder.
Select the SCD63X192S when you need a robust 63 mm bore actuator with equal bidirectional force and the convenience of integrated sensor mounting. If your application requires higher thrust, consider stepping up to the 80 mm bore SCD series, which provides 2268 N at the same 0.5 MPa pressure. For lower force needs, the 50 mm bore SCD delivers 825 N. Should your application involve significant side loading, a proper guided cylinder is necessary, as the dual-rod design improves guidance but is not a substitute for external linear guides.
This cylinder is a direct replacement for an existing AirTAC SCD63X192S, matching on bore, stroke, PT port thread, basic mounting, and the integrated magnet. Always verify that the operating pressure and mounting interface are identical to the original unit to ensure a seamless swap.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa, the force is 1402 N. At 0.7 MPa, it is 1962 N, and at the maximum operating pressure of 0.9 MPa, the force reaches 2523 N. The theoretical force at 1.0 MPa is 286 kgf.
Choose an SCD when your application needs perfectly equal force and speed in both directions, a rear rod end to mount a tool, stopper, or sensor flag, or enhanced bearing support for better side-load resistance and anti-rotation. A single-rod SC cylinder has a higher push force due to the full piston area but a lower pull force, and it cannot provide a rear actuation point.
