The AirTAC Airtac SCD Standard Cylinder SCD32X200S 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 SCD32X200S delivers balanced motion from both ends of its through-rod design, producing an identical 345 N of force in push and pull at 0.5 MPa. Its 12 mm diameter rod extends from each cap, giving you a rear connection point for stroke confirmation flags or secondary light tooling without adding an extra actuator.
This 200 mm stroke model includes a built-in magnet (-S suffix), so CMSG, DMSG or EMSG reed and solid-state sensors clip directly onto the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The compact aluminium body measures 187 mm (A dimension), and the adjustable air cushion on each end helps manage kinetic energy quietly at speeds up to 800 mm/s.

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 shuttle table or small transfer bar where the rear rod can push a return spring or drive a second station in sync, using the equal 621 N force available at 0.9 MPa.
The built-in magnet lets a DMSG sensor mount on the barrel to confirm full extension or retraction, while the rear rod carries a simple flag for a secondary mechanical limit switch.
With a 12 mm rod supported in both end caps, this cylinder resists piston rotation better than a single-rod type, helping keep a small alignment pin or label applicator oriented correctly.
Choose this 32 mm bore when your task needs equal bidirectional thrust around 345 N at standard plant air. If you require more force, the SCD40 series steps up to 528 N at the same 0.5 MPa. Because the rod protrudes from both ends, ensure the rear extension has clearance in your frame; if you only need thrust from one side, the single-rod SC32 series is a simpler fit. For a direct replacement, match bore, 200 mm stroke, PT ports, basic mount, and the -S magnet option to another genuine AirTAC SCD32X200S.
Double-rod checklist
Push and pull force are identical because the rod extends through both ends. At 0.5 MPa you get 345 N, at 0.7 MPa it is 483 N, and at the maximum operating pressure of 0.9 MPa the output is 621 N in both directions.
You pick an SCD when you need the same force and speed in both directions, or when the rear rod can do useful work like carrying a sensor target, a stopper, or a secondary tool. The dual-end support also gives the rod better guidance against twisting than a single-rod cylinder.
