The AirTAC Airtac SCD Standard Cylinder SCD200X100S 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, 100mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD200X100S is a heavy-duty double-rod pneumatic cylinder delivering symmetrical thrust of 15080 N in both extend and retract at 0.5 MPa, rising to 27143 N at the maximum operating pressure of 0.9 MPa. Its through-rod design, featuring a 40 mm diameter rod protruding from both ends, eliminates force differential between strokes, making it ideal for large fixtures requiring identical push-pull power. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This genuine AirTAC cylinder has a 200 mm bore, a 100 mm standard stroke, and a body length A(SCD) of 362 mm. It operates on 40 µm filtered air within a -20 to +70 °C range and includes adjustable air cushioning with a 33 mm cushion length to decelerate high-inertia loads smoothly. The PT 3/4 ports and M36x2 rod threads provide robust connections for industrial tooling on both sides of the piston.

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.

Related types: SC (single rod), SCJ (adjustable stroke), SCT (multi-position). SCD mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Operates a synchronized clamp from both ends of the cylinder, applying equal 15080 N force to secure large weldments or structural assemblies without distorting the workpiece.
Drives a transfer shuttle with a tooling plate mounted on the front rod, while the rear rod extension trips CMSG magnetic sensors for precise mid-stroke or end-of-travel signaling.
Provides identical push and pull force for a straightening or forming press, using the rear rod for a return stop or to mount a secondary feedback scale for position monitoring.
Select the SCD200X100S when you need balanced, high-force actuation from both ends of the cylinder. If your application requires slightly less force, consider stepping down to the SCD160 bore, which provides 9425 N at 0.5 MPa. For applications needing only a single working end, the standard SC single-rod series is a more economical choice. This cylinder is a direct replacement for an existing AirTAC SCD200X100S with PT ports and a magnet; ensure the bore, stroke, port thread, and sensor type match exactly.
For this 100 mm stroke, rod bending under side load is typically not a primary concern, but any external guidance should still be aligned precisely to prevent premature bearing wear. Remember that an SCD cylinder is not a guided unit and cannot support substantial off-axis loads without an external guide system.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa, the force is 15080 N; at 0.7 MPa, it is 21111 N; and at the maximum operating pressure of 0.9 MPa, it reaches 27143 N. The theoretical force at 1.0 MPa is 3075 kgf.
Choose the SCD when you need to mount tooling or sensors on both ends of the piston rod, or when your process requires absolutely equal force and speed in both directions. An SC single-rod cylinder has a higher push force due to the full piston area, but its pull force is reduced by the rod area. The SCD sacrifices that higher push force for perfect symmetry.
