The AirTAC Airtac SCD Standard Cylinder SCD32X200 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø12mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø32mm bore, 200mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X200 is a compact double-rod pneumatic cylinder that outputs an identical 345 N in push and pull at 0.5 MPa, making it predictable for tasks where the load must be moved with the same force in both directions. Its through-rod design has a 12 mm diameter rod protruding from both end caps, providing better guidance and anti-rotation than a single-rod cylinder of this size.
With a 200 mm stroke, this model is well inside the 1000 mm maximum standard stroke for the 32 bore, and its 21 mm adjustable air cushion at each end helps manage end-of-stroke impact. The body length (A dimension) is 187 mm, and it uses PT1/8 ports. This genuine AirTAC cylinder is built for reliable double-rod actuation in light automation.

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 | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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 a transfer shuttle between two positions with equal force and speed, using the rear rod for a counterbalance or sensor flag.
The dual-rod support naturally resists rotation, making it suitable for pushing small components without adding an external guide for light loads.
Applies identical clamping force from either end of the cylinder, useful in small jigs where the workpiece is accessed from two sides.
Choose the SCD32X200 when you need equal bidirectional force from a small bore. If 345 N is too low, stepping up to the SCD40 bore provides 528 N at the same 0.5 MPa pressure. If your application only needs force from one end, the single-rod SC32 series is a simpler and more compact alternative. For direct replacement, match the 32 mm bore, 200 mm stroke, PT1/8 ports, and confirm the mounting style (this is a basic model with no brackets). For strokes of 200 mm, rod bending under side load is generally not a concern, but any external guiding should still be verified for precise alignment.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. The force is 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at the maximum operating pressure of 0.9 MPa.
Choose the SCD when you need the piston rod to do work on both ends of the cylinder, require equal force and speed in both directions, or need the inherent anti-rotation and better rod guidance that a through-rod design provides.
