The AirTAC Airtac SCD Standard Cylinder SCD100X950S 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, 950mm stroke, PT1/2 ports and adjustable end cushioning.
This SCD100X950S double-rod cylinder provides a symmetrical 3681 N of force in both directions at 0.5 MPa, making it ideal for applications where identical push and pull thrust is non-negotiable. The 25 mm diameter rod passes through both end caps, offering enhanced guidance and the ability to mount tooling or sensors on the rear rod end.
With a 950 mm stroke, it stays within the standard range for the 100 mm bore, which supports up to 1500 mm. The body length A(SCD) is 263 mm, and the adjustable cushion is 29 mm. The integrated magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for reliable end-of-stroke detection.

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.

Shuttle tables and material transfer systems where the load must be moved with equal force and speed in both directions, eliminating process variation.
The built-in magnet enables clean external mounting of reed or solid-state sensors along the barrel, providing precise position feedback without brackets.
Operates tooling or clamping fixtures on both ends of the cylinder, such as a press plate on one side and an ejector mechanism on the other.
Choose the SCD100X950S when you need equal force in both directions and sensor feedback. If your load requires more thrust, stepping up to the 125 mm bore provides 5734 N at 0.5 MPa. For applications needing only a single-ended rod, the standard SC100 series is a lighter and more compact alternative. When replacing an existing cylinder, ensure a match on the 100 mm bore, 950 mm stroke, PT port thread, basic mounting, and the magnetic piston feature.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 3681 N, at 0.7 MPa it is 5153 N, and at the maximum operating pressure of 0.9 MPa it reaches 6626 N.
A double-rod cylinder provides equal force and speed in both directions, which is critical for processes that cannot tolerate asymmetry. The through-rod also offers better guidance and allows you to mount a load, stopper, or sensor target on the rear end.
