The AirTAC Airtac SCD Standard Cylinder SCD80X50TC 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, 50mm stroke, PT3/8 ports and adjustable end cushioning.
The SCD80X50TC is a double-rod pneumatic cylinder delivering an identical 2268 N of thrust in both extend and retract strokes at 0.5 MPa, thanks to its through-rod design where both piston sides share the same effective area. This specific model includes the TC centre trunnion mount, supplied with the TCM1 bracket (F-SC80TC), making it ideal for applications where the cylinder body must pivot during actuation.
With an 80 mm bore and a 25 mm rod protruding from both end caps, the unit provides inherent anti-rotation and can carry tooling or sensor flags on the rear rod. The 50 mm standard stroke is cushioned by 28 mm of adjustable pneumatic cushioning at each end, and the body length A(SCD) is 257 mm. It operates on 40 µm filtered air from 0.15 to 1.0 MPa, with a speed range of 30-800 mm/s.

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 TC centre trunnion mount allows the SCD80X50TC to swing freely, making it perfect for actuating transfer arms or flippers that move parts between two conveyor lines with equal speed and force in both directions.
With a rod extending from the rear cap, a secondary sensor flag or cam can be mounted to trigger end-of-stroke signals independently of the main tooling, simplifying control architecture on automated assembly cells.
The dual-rod support provides better resistance to rotation than a single-rod cylinder. Use the SCD80X50TC for clamping fixtures where the jaw must not twist, delivering 4082 N of clamping force at 0.9 MPa.
Choose the SCD80 bore when your application requires equal bidirectional force around 2268 N at standard plant pressure; for lighter tasks, the SCD63 bore provides 1402 N at the same 0.5 MPa. If your load only needs force in one direction and you do not require a rear rod extension, the single-rod SC series is a more economical choice. This centre-trunnion model is specifically for pivoting loads; for fixed surface mounting, select the LB foot mount instead.
As a direct replacement, match the 80 mm bore, 50 mm stroke, PT port thread, TC centre trunnion mounting style, and the absence of a magnet. This cylinder is not a substitute for a guided unit under side load, so if the rear rod will experience bending forces, add an external linear guide.
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 delivers 3175 N, and at the maximum operating pressure of 0.9 MPa it reaches 4082 N.
This specific code does not include the -S magnet option, so the piston does not have a magnetic ring. To use CMSG or DMSG sensors on the barrel, you would need to order the SCD80X50STC variant, which includes the built-in magnet.
