Airtac SCD Standard Cylinder SCD80X200SH
The AirTAC Airtac SCD Standard Cylinder SCD80X200SH 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, 200mm stroke, PT3/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD80X200SH
The SCD80X200SH is a double-acting, double-rod pneumatic cylinder that provides identical force and speed in both directions, delivering 2268 N of thrust each way at 0.5 MPa. The 25 mm diameter rod passes through both end caps, allowing you to mount tooling, a stopper, or a sensor flag on the rear rod end while maintaining a symmetric, non-rotating output. This model is fitted with a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and high-temperature Viton seals (H suffix) that shift the operating range to 0–150 °C.
With a 200 mm stroke, this cylinder is well within the 1500 mm maximum standard stroke for the 80 mm bore. The tie-rod construction provides a robust body length of 257 mm (A dimension for SCD), and the adjustable pneumatic cushioning at both ends, with a 28 mm cushion length, decelerates the piston smoothly. Ports are PT3/8, and the rod features an M20x1.5 male thread for attaching end effectors. At the maximum operating pressure of 0.9 MPa, the force output reaches 4082 N, making it a powerful choice for demanding two-sided actuation tasks in hot environments.

| 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 SCD80X200SH Is Used
Two-Sided Actuation
The through-rod design provides a driving force of 2268 N at 0.5 MPa from both ends simultaneously, ideal for operating two mechanisms in a synchronized sequence from a single cylinder.
High-Temp Stroke Sensing
With the built-in magnet and Viton seals for 0–150 °C operation, this cylinder is ready for hot environments where you need to confirm end-of-stroke position using CMSG/DMSG sensors mounted directly on the tie-rod barrel.
Shuttle Table Drive
The equal push/pull force of 4082 N at 0.9 MPa makes this cylinder perfect for driving a transfer shuttle back and forth, where consistent speed and force in both directions are critical for a smooth process.
Is the Airtac SCD Standard Cylinder SCD80X200SH the Right Cylinder?
This SCD80X200SH suits applications needing a balanced 2268 N output at 0.5 MPa in both directions. If your force requirement is lower, the 63 mm bore SCD delivers 1402 N, which may allow for a smaller, more economical installation. For higher force, stepping up to the 100 mm bore provides 3681 N. Because the double rod extends from both ends, ensure there is clearance for the rear rod's movement. If you only need force from one end, a single-rod SC series cylinder is a simpler alternative. This model is a direct replacement for any AirTAC SCD80X200SH cylinder; key matching points are the 80 mm bore, 200 mm stroke, PT3/8 ports, magnet option, and Viton seals.
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 SCD80X200SH FAQ
The push and pull forces are identical due to the double-rod design. At 0.5 MPa it is 2268 N, at 0.7 MPa it is 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 equal force and speed in both directions, a rear rod end for mounting external components like a sensor flag or stopper, or better resistance to rod rotation. The symmetrical rod also balances bearing loads, but for high side loads, a dedicated guided cylinder is still required.
