Airtac SDAD Double Rod Slim Cylinder SDAD32X20S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X20S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø32mm bore, 20mm stroke). The through-rod resists twisting and lets you drive a tool on one end while a switch or dog reads position on the other — with identical force in both directions.

About the Airtac SDAD Double Rod Slim Cylinder SDAD32X20S
The AirTAC SDAD32X20S is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber equally, the annular area remains constant, delivering identical push and pull forces of 345.6 N at 0.5 MPa. This symmetric output is ideal for balanced actuation without differential thrust.
Equipped with a built-in magnet (-S), this unit interfaces directly with AirTAC reed or electronic switches via the body sensor grooves. The short 20 mm stroke and space-saving footprint excel in tight machinery, while the fixed NBR bumpers absorb end-of-stroke impact. Operating at 30-500 mm/s, it handles a safe working load of roughly 207 N, yielding a 2:1 vertical lift margin of about 17.6 kg.
Airtac SDAD Double Rod Slim Cylinder SDAD32X20S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X20S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 20 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 male (B) |
| 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 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
| Max standard stroke | Up to 120 mm |
Because a rod occupies both cylinder chambers, the effective area — and therefore the force — is identical in both directions. Specifications follow the official AirTAC SDAD datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 kgf |
Force uses the annular (rod-side) area on both strokes, so extend and retract match. Actual usable force is lower than theoretical due to friction. Size with a safety margin.

Where the Airtac SDAD Double Rod Slim Cylinder SDAD32X20S Is Used
Gripper Jaw Actuation
Drives synchronized gripper arms where the equal 345.6 N extend and retract forces prevent jaw twisting during part clamping.
Transfer Shuttle
Mounts a pickup head on one rod end and a magnetic dog on the other, using the 20 mm stroke to shuttle components between stations.
Edge Guiding
Employs the anti-rotation properties of the dual 12 mm rods to hold web materials flat without lateral deflection.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X20S the Right Cylinder?
When sizing this 32 mm bore unit, evaluate both neighboring options. Dropping down to the SDAD25 provides 206.2 N at 0.5 MPa, whereas stepping up to the SDAD40 yields 527.8 N at 0.5 MPa. This SDAD32X20S strikes a middle ground with 345.6 N symmetric force, a 12 mm rod diameter, and a PT1/8 port. The female M6x1.0 rod-end threads accommodate standard mounting clevises.
The through-rod geometry inherently resists twisting, allowing you to mount a tool on one end and a position dog on the opposite side. Remember that a standard cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift. For load-holding security, integrate an external rod lock or pilot-operated check valve rather than relying on the fixed bumper, which solely decelerates the stroke end.
Quick checklist
- ✓ Need equal force both directions?
- ✓ Anti-rotation / dual-end mounting?
- ✓ Space for a rod that exits both ends
- ✓ Port/thread type (PT)
- ✓ 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 Leave clearance for the rod exiting both ends.
- check Avoid side load on either rod end.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAD Double Rod Slim Cylinder SDAD32X20S FAQ
The double-rod design provides equal force in both directions: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa. The theoretical maximum is 70 kgf at 1.0 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one end while mounting a dog on the other. The built-in magnet (-S) works with AirTAC reed or electronic switches fitted into the body grooves.
