Airtac SDAD Double Rod Slim Cylinder SDAD25X5B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X5B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 5mm 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 SDAD25X5B
The AirTAC SDAD25X5B is a double-acting compact cylinder featuring a 25 mm bore and a 5 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber. This geometry ensures push force equals pull force, delivering exactly 206.2 N at 0.5 MPa in either direction. The through-rod design inherently resists twisting, providing stable guidance for short clamping or ejecting tasks.
This specific SKU includes male M8x1.25 threads on both rod ends for direct mechanical mounting. The short 5 mm stroke minimizes overall axial footprint, saving valuable machine depth where a longer unit will not fit. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Operating speed spans 30-500 mm/s, and the body lacks a piston magnet, meaning it cannot support reed or electronic switches without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD25X5B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X5B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 5 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 SDAD25X5B Is Used
Short-Stroke Strip Clamping
Uses the 5 mm stroke and equal 206.2 N force to grip thin material strips securely without overshooting, leveraging the compact body to save depth in tight forming presses.
Symmetric Ejector Mechanism
Exploits the identical extend and retract forces to push and pull a part evenly, while the through-rod geometry prevents rotational twist during rapid ejection cycles.
Dual-End Tool Driving
Mounts an actuation pin on one male M8x1.25 rod end and a mechanical dog on the opposite end, allowing simultaneous tool operation and physical trip signaling.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X5B the Right Cylinder?
When sizing this unit, compare its 206.2 N output at 0.5 MPa against adjacent bores. Dropping down to the SDAD20 yields 131.9 N, while stepping up to the SDAD32 provides 345.6 N. Based on the 206.2 N figure, a safe working load is roughly 124 N (about 60 percent capacity), translating to a vertical lift capability of approximately 10.5 kg with a 2:1 safety margin. The dual-end male M8x1.25 rods allow you to drive a tool on one side while mounting a mechanical stop on the opposite side.
This model uses an M5x0.8 port and lacks the -S magnet, so position sensing is unavailable on this SKU. Remember that a standard double-acting cylinder does not hold its load if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 SDAD25X5B FAQ
The double-rod design provides equal force in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The theoretical maximum is 42 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need the -S variant (SDAD25X5BS) to enable magnetic position sensing.
