The AirTAC Airtac SCD Standard Cylinder SCD80X60TC is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø80mm bore, 60mm stroke, PT3/8 ports and adjustable end cushioning.
The SCD80X60TC is a double-acting, double-rod pneumatic cylinder that outputs identical force in both directions because the 25 mm rod passes through both end caps. At 0.5 MPa it produces 2268 N of thrust whether extending or retracting, making motion perfectly symmetrical for two-sided tooling. This model includes a centre trunnion (TC) mount, allowing the cylinder body to pivot as it strokes, which is essential when the load follows an arc.
With a 60 mm stroke, this unit is compact yet powerful, built around an 80 mm bore tie-rod body with a retracted body length of 257 mm (A dimension). The adjustable air cushion at each end decelerates the piston smoothly over the final 28 mm of travel. Ports are PT3/8, and the rod ends are threaded M20x1.5 for attaching fixtures on both sides.

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 | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 push-pull force and rear rod access make it perfect for shuttling a workpiece between two stations, where a stopper or sensor flag can be mounted on the back end without affecting the front tooling.
With the centre trunnion (TC) mount, this SCD80X60TC can swing to operate a diverter gate on a conveyor or a pivoting clamp, accommodating the arc motion without side-loading the rod bearings.
Delivers 4082 N of force at 0.9 MPa from both rod ends simultaneously, enabling a balanced pressing, staking, or crimping operation where tooling is attached to each side of the cylinder.
Choose the SCD80 bore when your application needs roughly 2268 N of balanced force at 0.5 MPa. If you can work with around 1402 N, stepping down to a 63 mm bore reduces air consumption and physical size; if you need closer to 3681 N, the 100 mm bore is the next logical step up. This TC variant is specifically for pivoting applications—if your load moves in a straight line, a basic or foot-mounted (LB) SCD80 is simpler and often cheaper.
This double-rod cylinder is ideal when you need to mount tooling or sensors on the rear rod, but remember it is not a guided cylinder. For strokes longer than 300 mm or any significant side load, add an external guide rail to protect the rod bearings from bending moments. As a direct replacement, match the 80 mm bore, 60 mm stroke, PT3/8 ports, centre trunnion mount, and absence of a magnet.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it outputs 2268 N, at 0.7 MPa it outputs 3175 N, and at the maximum operating pressure of 0.9 MPa it delivers 4082 N in both directions.
Choose an SCD when you need perfectly equal force and speed in both directions, or when you need to mount tooling, a cam, or a position sensor on a rear rod. The through-rod design also provides better guidance and anti-rotation than a single-rod cylinder, though it is still not a substitute for a fully guided unit under heavy side loads.
