Airtac SCD Standard Cylinder SCD32X80S
The AirTAC Airtac SCD Standard Cylinder SCD32X80S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø12mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø32mm bore, 80mm stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD32X80S
The SCD32X80S is a compact double-rod pneumatic cylinder where the 12 mm piston rod extends from both end caps, producing identical push and pull force of 345 N at 0.5 MPa. This through-rod design gives you a rear rod end that can carry a sensor flag, a mechanical stop, or secondary light tooling, while the symmetrical bearing load improves rod guidance for the 80 mm stroke.
Equipped with a built-in magnet (the -S suffix), this model accepts CMSG, DMSG, or EMSG sensors directly on the tie-rod barrel—no extra brackets needed. The body length A(SCD) is 187 mm, and the adjustable air cushion (21 mm) decelerates the piston smoothly at both ends. Ports are PT1/8 with an M10x1.25 rod thread, operating on 40 µm filtered air from 0.15 to 1.0 MPa.

| Stroke | 80 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 21 mm |
| Max stroke | Up to 1000 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 (Ø32mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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 SCD32X80S Is Used
Two-Sided Pick-and-Place
The rear rod operates a secondary gripper or ejector, synchronised perfectly with the front tooling for compact part transfer.
Rear Stroke Sensing
With the built-in magnet, mount a CMSG sensor on the rear barrel to confirm full retraction via the back rod's motion.
Non-Rotating Pusher
The twin-rod support resists rotation, making it suitable for light-duty pressing or aligning components without a separate anti-rotate guide.
Is the Airtac SCD Standard Cylinder SCD32X80S the Right Cylinder?
Choose the 32 mm bore SCD when your application needs equal bidirectional force around 345 N at 0.5 MPa. If you need more thrust, step up to the SCD40 (528 N at 0.5 MPa) with its 16 mm rod. For purely single-sided actuation where only one rod end is used, the standard SC single-rod cylinder gives you a larger push force from the full piston area and is usually the more economical choice. The double-rod layout is not a guided cylinder; if the 80 mm stroke sees any side load, add an external guide rail or switch to a guided cylinder. For a direct replacement, match the 32 mm bore, 80 mm stroke, PT1/8 ports, basic mounting, and the -S magnet option.
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 SCD32X80S FAQ
Because the rod passes through both end caps, the effective piston area is identical in both directions. The force is 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at the 0.9 MPa maximum operating pressure—equal for both push and pull strokes.
Pick the SCD when you need to mount tooling or sensors on both ends of the rod, require perfectly equal force and speed in both directions, or want the extra rod guidance that the through-rod provides. The SC single-rod cylinder delivers higher push force from the full bore area but cannot offer a rear rod connection point.
