Airtac SCD Standard Cylinder SCD32X160S
The AirTAC Airtac SCD Standard Cylinder SCD32X160S 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, 160mm stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD32X160S
The SCD32X160S is a double-rod pneumatic cylinder where the 12 mm piston rod extends from both ends, giving you identical push and pull force of 345 N at 0.5 MPa (621 N at 0.9 MPa) in each direction. This symmetry is invaluable when you need to mount tooling, a stopper, or a position-sensing flag on the rear rod, or when the load must be guided from both sides of the piston.
This model includes a built-in magnet (-S suffix), so you can directly clamp CMSG, DMSG, or EMSG reed or solid-state sensors onto the tie-rod barrel for non-contact end-of-stroke detection. With a 160 mm stroke, a 21 mm air cushion at each end, and PT1/8 ports, it fits neatly into compact two-sided actuation and transfer tasks where balanced motion matters more than raw force.

|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø32 mm |
| Rod diameter | Ø12 mm (both ends) |
| Stroke | 160 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 SCD32X160S Is Used
Two-Sided Actuation
The rod protruding from both ends lets you drive two mechanisms from one cylinder body, such as opening and closing a pair of grippers or gates simultaneously with perfectly synchronized motion.
Rear-Mounted Stroke Sensing
With the built-in magnet, attach a CMSG sensor to the rear rod's path. This is ideal when the front end is inaccessible or crowded, letting you confirm full retraction from the back of the machine.
Anti-Rotation Pusher
The dual-rod design inherently resists piston rotation. Use it as a light-duty pusher in a pick-and-place where a single rod might twist, keeping your end-effector aligned without adding external guides.
Is the Airtac SCD Standard Cylinder SCD32X160S the Right Cylinder?
Choose the SCD32 bore when your application needs symmetric force around 345 N at 0.5 MPa. If you require more thrust, the SCD40 steps up to 528 N at the same pressure. For a single-rod solution where only one end does the work, the standard SC32 series is a simpler, shorter alternative. This double-rod cylinder is a direct replacement for another AirTAC SCD32X160-S with the same PT port thread and basic mounting.
At a 160 mm stroke, the through-rod design provides better bearing support than a single-rod cylinder, but it is not a substitute for a fully guided cylinder if the rod tip sees significant side load. For long-stroke pushing with lateral forces, consider adding an external linear guide.
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 SCD32X160S FAQ
Because the rod passes through both end caps, the effective piston area is identical on both sides. The force is 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at the maximum operating pressure of 0.9 MPa. The theoretical force at 1.0 MPa is 70 kgf.
Choose the SCD when you need equal force and speed in both directions, a rear rod extension for mounting a sensor flag or secondary tooling, or better resistance to rod bending and rotation. If you only need force from one end and want a shorter overall length, the single-rod SC32 is the better fit.
