The AirTAC Airtac SCD Standard Cylinder SCD32X45 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø12mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø32mm bore, 45mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X45 is a compact double-acting, double-rod air cylinder that outputs an identical 345 N of force in both extend and retract directions at 0.5 MPa, thanks to its through-rod design where the 12 mm rod is subtracted from both piston areas. This balanced output makes it ideal for light-duty two-sided tooling, symmetrical clamping, or any short-stroke task where consistent bidirectional thrust is critical.
With a 45 mm stroke and a body length of 187 mm, this tie-rod cylinder fits neatly into confined automation cells. The adjustable air cushion (21 mm) at each end decelerates the piston smoothly, protecting end caps from impact. It operates on 40 µm filtered air from 0.15 to 1.0 MPa, with a speed range of 30-800 mm/s, and the PT1/8 ports and M10x1.25 rod threads are standard.

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 | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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 rod extending from both ends allows simultaneous operation of two mechanisms from one compact cylinder, such as triggering dual reject gates on a small conveyor.
The dual-rod connection provides inherent anti-rotation, making it suitable for a light-duty push plate that must stay aligned without adding an external guide rail.
Delivers equal 345 N clamping force in both directions, perfect for a fixture that must grip a part from two opposite sides with precisely balanced pressure.
Choose the SCD32X45 when you need equal push-pull force in a small footprint. If the 345 N force at 0.5 MPa is marginal, stepping up to the SCD40 bore provides 528 N, while the SCD32 is the right choice if space and weight are the primary constraints. For applications where a rear rod is not needed, a single-rod SC32 cylinder offers a higher push force from the full piston area.
As a direct replacement, match the 32 mm bore, 45 mm stroke, PT port thread, and basic mounting. If you later need magnetic piston sensing, order the SCD32X45-S variant. Remember that a through-rod provides better guidance than a single rod, but it is not a substitute for a proper guided cylinder if the load applies a significant side force.
Double-rod checklist
The push and pull forces are identical because it is a double-rod cylinder. At 0.5 MPa, both directions produce 345 N. The force increases to 483 N at 0.7 MPa and reaches 621 N at the maximum operating pressure of 0.9 MPa.
Choose the SCD32 when you need a rear rod to mount a sensor flag, a manual override button, or a second tool. It also provides equal force and speed in both directions and better rod bearing support, which is useful when the load is not purely axial.
