The AirTAC Airtac SCD Standard Cylinder SCD200X150 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. Ø200mm bore, 150mm stroke, PT3/4 ports and adjustable end cushioning.
This SCD200X150 double-rod pneumatic cylinder provides an identical 15080 N of force in both the extend and retract strokes at 0.5 MPa, thanks to its through-rod design that equalizes the effective piston area. The 40 mm diameter rod protrudes from both ends, allowing you to mount tooling, a mechanical stop, or position sensors on the rear side while the front side performs the primary work, giving you a naturally synchronized, two-sided actuation point from a single air supply.
The cylinder body measures 362 mm (A dimension) and features an adjustable air cushion with a 33 mm length to decelerate the massive 200 mm bore piston smoothly. Operating on filtered air from 0.15 to 1.0 MPa, it can generate up to 27143 N of thrust at the maximum 0.9 MPa pressure, making it a robust choice for heavy-duty fixtures that demand balanced, controlled motion from both ends of the actuator.

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 | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | 21111 N |
| Max (@1.0 MPa) | 3075 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 15080 N force in both directions provides perfectly balanced acceleration and deceleration for a shuttle table moving large castings or weldments between stations.
Mount a pressing tool on the front rod and a stripper plate on the rear rod to create a self-contained press-and-eject station with a single synchronized cylinder.
Use the rear rod extension to mount a sensor flag or a mechanical stop, enabling end-of-stroke confirmation without interfering with the primary tooling on the front end.
Select the SCD200X150 when your application requires a powerful, balanced push-pull action, such as driving a large transfer shuttle or a dual-sided clamping fixture. If 15080 N at 0.5 MPa exceeds your requirement, stepping down to the SCD160 bore reduces the force to 9425 N, while still maintaining the equal bidirectional output. For applications needing force in only one direction, the single-rod SC200 series provides a higher push force due to the full piston area on the blind side.
As a direct replacement, this unit matches any existing AirTAC SCD200X150 with PT ports and a basic mount. When ordering a replacement, verify five key points: the 200 mm bore, 150 mm stroke, PT port thread, the specific SCD mounting accessory (if any), and the presence of a magnet. For this 150 mm stroke, rod bending is typically not a concern, but if your tooling applies a significant side load, an external guide rail or switching to a guided cylinder is recommended to protect the rod bearings.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are equal. At 0.5 MPa it outputs 15080 N, at 0.7 MPa it is 21111 N, and at the maximum operating pressure of 0.9 MPa it reaches 27143 N in both directions.
Choose the SCD200 when you need identical force and speed in both directions, or when you need to attach tooling, a brake, or sensors to the rear rod. The single-rod SC200 will provide a higher push force on the blind side but a much lower pull force on the rod side.
