Airtac SCD Standard Cylinder SCD80X160TC
The AirTAC SCD Standard Cylinder SCD80X160TC 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, 160mm stroke, PT3/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD80X160TC
The SCD80X160TC 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 generates 2268 N of thrust each way, making it a balanced actuator for tasks where the return stroke must match the power of the advance stroke. This model includes a centre trunnion (TC) mount, which lets the cylinder pivot during operation, absorbing angular movement in the application.
The 80 mm bore body has a retracted length (A dimension) of 257 mm and uses an adjustable air cushion of 28 mm at each end to decelerate the piston smoothly. Its PT3/8 ports and M20x1.5 rod threads are standard for this bore class. With a 160 mm stroke, it is well within the 1500 mm maximum standard stroke for this bore, keeping it a readily available, off-the-shelf configuration.

| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
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.
Theoretical Output Force (Ø80mm, double rod)
| 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.

Where the Airtac SCD Standard Cylinder SCD80X160TC Is Used
Reciprocating Transfer Shuttles
The equal push/pull force of the through-rod design provides consistent motion in both directions, ideal for shuttling parts between two stations where timing and force must be identical for each half of the cycle.
Dual-End Fixturing & Stops
The rear rod extension can be used to mount a hard stop, a secondary tool, or a sensor flag, turning one cylinder into a compact, self-contained station without needing extra brackets on the front end.
Pivoting Sorting Gates
With the TC centre trunnion mount, this cylinder can pivot freely to actuate a sorting gate or diverter flap, where the balanced force on both rods ensures smooth, chatter-free movement under load.
Is the Airtac SCD Standard Cylinder SCD80X160TC the Right Cylinder?
This 80 mm bore double-rod cylinder is a mid-range workhorse. If you need more force, stepping up to the 100 mm bore provides 3681 N at the same 0.5 MPa. For lighter, more compact applications, the 63 mm bore delivers 1402 N. Choose this SCD over a single-rod SC when you need to mount tooling, a sensor flag, or a mechanical stop on the rear rod, or when you require perfectly symmetrical speed and force for a process.
For a direct replacement, match the 80 mm bore, 160 mm stroke, PT3/8 port thread, and the TC centre trunnion mounting style (which uses the F-SC80TC bracket). This model does not have a built-in magnet, so if you need barrel-mounted sensors, specify the -S option. For strokes of 300 mm or longer, consider the unsupported rod length; at 160 mm, rod buckling is less of a concern, but an external guide is still recommended if the load applies any significant side force.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCD Standard Cylinder SCD80X160TC FAQ
Because the SCD is a double-rod cylinder, the piston area is reduced by the rod area on both sides, making the push and pull forces identical. For the 80 mm bore with a 25 mm rod, the force is 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at the maximum operating pressure of 0.9 MPa.
You would choose the SCD when your application benefits from a rod extending from both ends. This allows you to attach tooling or sensors to the rear rod, provides better rod guidance and anti-rotation than a single-rod cylinder, and delivers perfectly equal force and speed in both directions, which is critical for symmetrical back-and-forth operations.
