Airtac SDAD Double Rod Slim Cylinder SDAD25X55S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X55S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm 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 SDAD25X55S
The AirTAC SDAD25X55S is a compact double-acting 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, yielding equal push and pull forces of 206.2 N at 0.5 MPa. This symmetry is ideal for driving loads that require consistent momentum in both strokes.
The integrated -S piston magnet supports AirTAC reed or electronic switches for end-position sensing. A fixed NBR bumper at each end decelerates the stroke, while the short body design saves axial mounting depth. The 10 mm rods provide inherent anti-rotation stability, allowing you to mount a tool on one end and a sensor dog on the opposite.
Airtac SDAD Double Rod Slim Cylinder SDAD25X55S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X55S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 55 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø25mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 SDAD25X55S Is Used
Symmetric Transfer Chuck
Grips and shifts small components with matched 206.2 N force in both directions, preventing uneven wear on the gripper jaws.
Anti-Rotation Guide Arm
Uses the through-rod geometry to resist twisting while positioning a part, keeping the alignment precise over the 55 mm travel.
Dual-End Pick and Place
Drives a pickup nozzle on the front face while the rear rod end triggers a solid-state switch, saving space on the actuation carriage.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X55S the Right Cylinder?
When sizing this model, consider the adjacent bores: the SDAD20 provides 131.9 N at 0.5 MPa, while the SDAD32 offers 345.6 N. The 25 mm bore hits a balanced middle ground with a safe working load of roughly 124 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of approximately 10.5 kg with a 2:1 safety margin.
This configuration includes a 55 mm stroke, M5x0.8 air port, and female M5x0.8 rod-end threads. Note that a plain cylinder drifts when air is lost or the valve centers; use an external rod lock or pilot-operated check valve for load holding. The fixed bumper is not an adjustable cushion or brake.
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 SDAD25X55S FAQ
Because the double-rod design provides equal annular area on both sides, the push and pull forces are identical: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa.
Yes, the through-rod resists rotation and allows you to mount a tool on one end and a dog for a reed or electronic switch on the other. The built-in magnet enables position feedback via standard AirTAC sensors.
