The AirTAC Airtac SCD Standard Cylinder SCD100X500S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø100mm bore, 500mm stroke, PT1/2 ports and adjustable end cushioning.
This SCD100X500S double-rod cylinder generates an identical 3681 N of force in both directions at 0.5 MPa, thanks to its through-rod design where both piston faces share the same effective area. The 25 mm rod extends from both ends, providing a symmetric mounting platform for tooling or sensors on the rear cap side while delivering a full 500 mm of usable stroke.
Equipped with a built-in magnet (-S suffix), it accepts CMSG, DMSG, or EMSG reed and solid-state sensors directly on the tie-rod barrel for non-contact position feedback. The PT1/2 ports and adjustable air cushion (29 mm length) allow smooth deceleration of large transferred masses, with a body length A(SCD) of 263 mm forming the base retracted dimension.

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 | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | 5154 N |
| Max (@1.0 MPa) | 751 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 rear rod can carry a mirror-image gripper or pusher plate, allowing a single cylinder to transfer parts between two parallel conveyors with perfectly synchronized motion.
With the built-in magnet, mount a DMSG sensor on the rear tie-rod to detect end-of-stroke from the back side, keeping the front rod area clear for tooling in tight automation cells.
The dual-rod bearing support resists rotation better than a single-rod cylinder, making it suitable for pushing wide, flat products onto a palletizer infeed without adding an external anti-rotate guide.
Step up to the SCD125 bore if your application demands more than 3681 N at 0.5 MPa, as the 125 mm bore provides 5734 N. For purely single-sided actuation, a single-rod SC100 cylinder offers a higher push force (4019 N at 0.5 MPa) by using the full piston area, making it the better choice when rear-rod access is not required. At a 500 mm stroke, consider the unsupported rod column; if side loads are present, an external guide rail or a guided cylinder is necessary to prevent rod bending and premature bearing wear.
This model is a direct replacement for another AirTAC SCD100X500S matching bore, stroke, PT port thread, basic mounting, and the integrated magnet. It is not dimensionally interchangeable with ISO 15552 cylinders.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are equal. At 0.5 MPa it produces 3681 N, at 0.7 MPa it produces 5153 N, and at the maximum operating pressure of 0.9 MPa it produces 6626 N in both directions.
Choose the SCD when you need equal force and speed in both directions, or when you need to mount tooling, a mechanical stop, or a sensor flag on the rear rod. The through-rod also provides better guidance and anti-rotation than a single-rod cylinder, though it is not a substitute for a fully guided cylinder under heavy side loads.
