Airtac SDAD Double Rod Slim Cylinder SDAD32X55SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X55SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø32mm bore, 55mm 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 SDAD32X55SB
The AirTAC SDAD32X55SB is a 32 mm bore, double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, delivering an equal push and pull force of 345.6 N at 0.5 MPa. This symmetric output is ideal for balanced tooling, while the through-rod geometry inherently resists twisting during linear motion.
This specific configuration includes a built-in piston magnet for position sensing alongside male M10x1.25 rod threads on both ends. Operating at speeds of 30-500 mm/s, the unit relies on a fixed NBR bumper at each stroke end to decelerate the piston. The short body profile saves axial mounting depth compared to standard round-body cylinders, fitting easily into tight machinery.
Airtac SDAD Double Rod Slim Cylinder SDAD32X55SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X55SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 55 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 SDAD32X55SB Is Used
Symmetric Transfer Chuck
Uses the equal 345.6 N push and pull force to grip and release delicate wafers without directional force bias, preventing chuck warping.
Anti-Rotation Edge Guide
The through-rod resists twisting to keep the web material aligned, while the male M10x1.25 threads mount custom guide rollers on both ends.
Dual-End Stamping Station
Mounts a stamping die on one rod end and a position dog on the other, using the magnet to trigger an electronic switch at exact 55 mm intervals.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X55SB the Right Cylinder?
When sizing this 32 mm bore model, consider the neighboring bores for your force requirements. Stepping down, the SDAD25 provides 206.2 N at 0.5 MPa, while stepping up, the SDAD40 yields 527.8 N at 0.5 MPa. This SDAD32X55SB delivers 345.6 N at 0.5 MPa, translating to a safe working load of roughly 207 N or a vertical lift capacity of about 17.6 kg with a 2:1 safety margin. It features a PT1/8 port and a 55 mm stroke.
The dual-end through-rod allows you to drive a work piece on one side while mounting a dog or sensor on the opposite end. Note that a plain cylinder does not hold position if air pressure is lost or the valve is centered; the piston will drift, as the fixed NBR bumper only decelerates near the stroke end. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. This unit has the -S magnet for AirTAC reed or electronic switches and the -B option for male M10x1.25 rod threads at both ends.
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 SDAD32X55SB FAQ
The force is equal in both directions due to the double-rod design. It provides 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a theoretical maximum of 70 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
The through-rod exiting both ends provides equal extend and retract forces, resists mechanical twisting, and allows you to mount tooling on one end while using the other end to trigger a reed or electronic switch via the built-in magnet.
