The AirTAC Airtac SCD Standard Cylinder SCD63X65STC is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 65mm stroke, PT1/4 ports and adjustable end cushioning.
The SCD63X65STC is a double-acting, double-rod pneumatic cylinder that outputs exactly 1402 N of force in both directions at 0.5 MPa, thanks to its symmetrical piston area. With a 20 mm rod protruding from both end caps and a compact 65 mm stroke, it is a natural fit for short-throw, two-sided tooling where equal speed and thrust are non-negotiable.
This model comes factory-equipped with a built-in magnet (-S) and a centre trunnion mount (TC) including the TCM1 bracket, allowing the entire cylinder body to pivot. The 28 mm air cushion at each end decelerates the piston quietly, and the body length A(SCD) of 210 mm keeps the assembly rigid during the swing.

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 | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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.
The through-rod design lets you mount a gripper on the front and a counterbalance or secondary tool on the rear, moving parts between stations with perfectly synchronized motion.
Delivers an identical 2523 N of clamping pressure at 0.9 MPa from both rod ends, ideal for symmetrical fixtures where uneven force would distort the workpiece.
The TC centre trunnion mount lets the cylinder body swing, while the built-in magnet allows CMSG/DMSG sensors to confirm end-of-stroke position at both extremes of the arc.
Choose the SCD63 bore when your application needs roughly 1400 N of balanced force at standard plant pressure. If you can accept a smaller footprint and about 825 N, step down to the SCD50; for heavier tooling requiring 2268 N, the SCD80 is the next logical step. This STC variant is specifically for pivoting loads—if your design calls for a fixed panel mount, consider the FA front flange instead.
This is a genuine AirTAC double-rod cylinder. To guarantee dimensional and performance compatibility when replacing an existing unit, match all five points: 63 mm bore, 65 mm stroke, PT port thread, TC centre trunnion mounting, and the -S magnet for sensor feedback. Note that a double-rod cylinder is not a substitute for a guided cylinder under side load; for strokes over 300 mm, external guides are mandatory, but at 65 mm the twin-rod bearing support is inherently stable.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 1402 N, at 0.7 MPa it produces 1962 N, and at the maximum operating pressure of 0.9 MPa it produces 2523 N.
You would choose the SCD when you need to mount tooling or a sensor flag on the rear rod, or when you require perfectly equal force and speed in both directions. The twin-rod bearing support also provides better guidance and anti-rotation than a single-rod cylinder of the same bore.
