Airtac SDAD Double Rod Slim Cylinder SDAD32X55B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X55B 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 SDAD32X55B
The AirTAC SDAD32X55B is a compact double-acting cylinder featuring a 32 mm bore and a 55 mm stroke. Because the 12 mm piston rod exits both ends of the riveted body, the annular area is identical in each chamber. This geometry ensures push force equals pull force, delivering exactly 345.6 N at 0.5 MPa in both directions, which simplifies symmetric load balancing.
This specific SKU includes male M10x1.25 rod threads on both ends for direct tool mounting. The short body design minimizes axial footprint compared to standard round-body options. End-of-stroke energy is managed solely by a fixed NBR bumper that decelerates the piston, rather than an adjustable air cushion. Note this version lacks a piston magnet, so position sensing is not supported without the -S option.
Airtac SDAD Double Rod Slim Cylinder SDAD32X55B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X55B |
|---|---|
| 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 SDAD32X55B Is Used
Symmetric Transfer Chuck
Drives a dual-sided gripper where the equal 345.6 N extend and retract forces prevent twisting during high-speed part transfers.
PCB Edge Guide
Uses the male M10x1.25 rod ends to push a straightening jig from both sides, keeping electronic panels perfectly aligned.
Vertical Lift Platform
Lifts an 18 kg fixture with a 2:1 safety margin, relying on the through-rod to resist torsion during elevation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X55B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD25 yields 206.2 N at 0.5 MPa, while stepping up to the SDAD40 provides 527.8 N at 0.5 MPa. For this 32 mm bore, a safe working load is approximately 207 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 17.6 kg with a 2:1 safety margin.
The through-rod design inherently resists twisting and allows driving a mechanism on one end while clearing a dog or fixture on the opposite side. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the NBR bumper only decelerates near stroke end and cannot hold a load. For secure positioning without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration features a PT1/8 port, male M10x1.25 rod threads, and no magnet.
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 SDAD32X55B FAQ
The double-rod design provides equal force in both directions: 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.
Yes, the through-rod design allows mounting tooling on both male M10x1.25 threaded ends simultaneously. This configuration also resists rotation, but note this specific SKU lacks a magnet for switch sensing.
