Airtac SCD Standard Cylinder SCD80X160STC
The AirTAC Airtac SCD Standard Cylinder SCD80X160STC 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 SCD80X160STC
The SCD80X160STC is a double-acting, double-rod pneumatic cylinder that provides identical 2268 N of force in both push and pull directions at 0.5 MPa, thanks to its through-rod design. The 25 mm diameter rod extends from both ends, offering a balanced thrust of 4082 N at the maximum 0.9 MPa operating pressure, making it ideal for symmetrical tooling or dual-sided actuation.
This specific model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a TC centre trunnion mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during operation. With a 28 mm adjustable air cushion and a body length A of 257 mm, it provides smooth deceleration in a compact, tie-rod construction for industrial tasks.
Airtac SCD Standard Cylinder SCD80X160STC Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD80X160STC |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø80 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 160 mm |
| 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 SCD80X160STC Is Used
Dual-Sided Transfer Shuttles
The equal push/pull force and rear rod make this cylinder perfect for shuttling parts between two parallel conveyor lines, where a tool can be mounted on each rod end for bidirectional transfer.
Symmetrical Clamping Fixtures
Achieve perfectly balanced clamping pressure from two sides simultaneously. The through-rod design ensures both clamping arms, mounted on opposite ends, apply the exact same 2268 N of force at 0.5 MPa.
Pivoting Actuator with Sensing
The TC centre trunnion mount allows the cylinder body to swing, while the built-in magnet enables precise end-of-stroke detection with CMSG sensors, ideal for controlling the tilt angle on a dump hopper or diverter gate.
Is the Airtac SCD Standard Cylinder SCD80X160STC the Right Cylinder?
This 80 mm bore SCD unit is a strong mid-range choice, stepping up from the 63 mm bore (1402 N at 0.5 MPa) for applications needing more force without moving to the larger 100 mm bore (3681 N). Its double-rod design is the correct selection when you require equal speed and force in both directions or need to attach tooling, a stopper, or a sensor flag to the rear rod. For a 160 mm stroke, side loading is typically not a primary concern, but any off-axis force should be managed with an external guide. This model is a direct replacement for another AirTAC SCD80X160 cylinder with a PT port, TC mount, and magnet, matching all five critical interface points.
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 SCD80X160STC FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 2268 N, at 0.7 MPa it produces 3175 N, and at the maximum operating pressure of 0.9 MPa, the force is 4082 N in both directions.
Choose the SCD when you need perfectly equal force and speed in both directions, or when you need to utilize the rear rod for mounting a secondary tool, a mechanical stop, or an external sensor flag. The through-rod also provides better support for the piston, reducing uneven bushing wear compared to a single-rod cylinder in high-cycle applications.
