The AirTAC Airtac SCD Standard Cylinder SCD100X260 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. Ø100mm bore, 260mm stroke, PT1/2 ports and adjustable end cushioning.
The SCD100X260 is a double-acting, double-rod pneumatic cylinder that provides identical thrust in both directions—3681 N at 0.5 MPa and 6626 N at the maximum operating pressure of 0.9 MPa. Because the 25 mm rod passes through both end caps, the effective piston area is the same on the push and pull strokes, making this actuator ideal for applications where a rear tooling plate, stroke sensor flag, or manual override must be mounted on the back side.
With a 100 mm bore and a 260 mm stroke, this tie-rod cylinder uses a PT1/2 port and features an adjustable air cushion (29 mm length) at each end to decelerate the piston smoothly. The body length A(SCD) is 263 mm, and the retracted overall length is longer than an equivalent single-rod SC cylinder because the rod protrudes from both caps. Operating speed ranges from 30 to 800 mm/s on filtered air at 0.15–1.0 MPa.

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 | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | 5154 N |
| Max (@1.0 MPa) | 751 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 through-rod lets you mount identical grippers or tooling plates on both ends, enabling a single cylinder to shuttle parts between two parallel conveyors with equal speed and force in each direction.
Attach a sensor flag or cam to the rear rod extension to trigger external limit switches or proximity sensors, providing end-of-stroke confirmation without interfering with the front tooling.
Use the equal push/pull force of 3681 N at 0.5 MPa to drive a two-sided clamp or press where both the advance and retract strokes perform active work on separate fixtures.
Choose the SCD100X260 when you need equal force and speed in both directions and a rear rod extension for dual-sided actuation or sensing. If your load requires roughly 20% less thrust, the SCD80 bore generates 2268 N at 0.5 MPa and may reduce air consumption. For applications that only need force from one end, the single-rod SC100 series is a simpler, more compact alternative.
This cylinder is a direct replacement for another AirTAC SCD100 double-rod unit matching the 260 mm stroke, PT port thread, basic mounting, and no magnet. At a 260 mm stroke, the unsupported rod length is moderate, but if the tooling applies a side load or the rod is connected to a guided carriage, consider adding an external linear guide or switching to a guided cylinder to protect the rod bearings from premature wear.
Double-rod checklist
Push and pull force are identical on this double-rod cylinder. At 0.5 MPa it delivers 3681 N, at 0.7 MPa it delivers 5153 N, and at the maximum operating pressure of 0.9 MPa it delivers 6626 N. The theoretical force at 1.0 MPa is 751 kgf.
Choose the SCD when you need a rear rod extension for mounting tooling, a stopper bolt, or a sensor target, or when you require perfectly equal force and speed in both directions. The through-rod also provides better guidance than a single rod, though it is not a substitute for an externally guided cylinder under significant side loads.
