Airtac SCD Standard Cylinder SCD80X100S
The AirTAC SCD Standard Cylinder SCD80X100S 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, 100mm stroke, PT3/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD80X100S
The SCD80X100S is a double-acting, double-rod pneumatic cylinder that produces identical force in both directions—2268 N at 0.5 MPa—because the 25 mm rod passes through both end caps. This symmetry makes it ideal for applications where a rear rod extension is needed for tooling, a stroke sensor flag, or a mechanical stop.
With a 100 mm stroke and a body length A(SCD) of 257 mm, this model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. The adjustable air cushion (28 mm) decelerates the piston at stroke ends, and the PT3/8 ports provide reliable flow for speeds up to 800 mm/s.
Airtac SCD Standard Cylinder SCD80X100S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD80X100S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø80 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 100 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 SCD80X100S Is Used
Two-Sided Transfer Shuttles
The rear rod can carry a second tooling plate or a counterbalance, enabling a single cylinder to shuttle parts between two parallel conveyor lines with perfectly synchronized motion.
Rear-Mounted Stroke Sensing
With the built-in magnet, a DMSG sensor on the rear end cap detects the piston's position without interfering with the front tooling, keeping the primary work zone clear and accessible.
Anti-Rotation Pushers
The dual-rod support provides better resistance to twisting than a single-rod cylinder, making it suitable for pushing flat panels or sheets where maintaining alignment is critical.
Is the Airtac SCD Standard Cylinder SCD80X100S the Right Cylinder?
Choose the SCD80 bore when your application needs about 2268 N of balanced force per direction at standard plant pressure. If you require more thrust, stepping up to the SCD100 delivers 3681 N at the same 0.5 MPa. For tasks that only need actuation from one end, the single-rod SC80 is a lighter and more compact alternative.
To replace an existing SCD80X100S, match five points: 80 mm bore, 100 mm stroke, PT3/8 ports, the basic mounting style, and the built-in magnet. This cylinder does not include a mounting bracket; for pivoting loads, order the TC centre trunnion kit (F-SC80TC) separately. Note that the through-rod design improves bearing support but does not eliminate the need for external guides under significant side loads.
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 SCD80X100S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. At 0.5 MPa it outputs 2268 N, at 0.7 MPa it outputs 3175 N, and at 0.9 MPa it reaches 4082 N in both directions.
Choose the SCD when you need a rear rod extension for mounting sensors, stoppers, or secondary tooling, or when you require perfectly equal force and speed in both directions. The through-rod also provides better guidance than a single-rod SC, though it is not a replacement for a fully guided cylinder under heavy side loads.
