Airtac SDAD Double Rod Slim Cylinder SDAD25X5SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X5SB 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 SDAD25X5SB
The AirTAC SDAD25X5SB is a compact double-acting cylinder featuring a piston rod exiting both ends of its riveted body. Because the rod occupies each chamber, the annular area stays identical, yielding an equal push and pull force of 206.2 N at 0.5 MPa. This symmetry is highly beneficial when driving rigid loads that require balanced resistance in both travel directions.
The through-rod geometry inherently resists twisting, allowing you to mount a work tool on one male M8x1.25 threaded end and a position dog on the opposite side. Fitted with a built-in magnet, it supports reed or electronic switches in the body grooves. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD25X5SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X5SB |
|---|---|
| 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 SDAD25X5SB Is Used
Gripper Jaw Sync
Drives opposing gripper fingers with equal 206.2 N force in both directions, maintaining parallel clamping on delicate electronics without rotational twist.
Short Stroke Punching
Executes a 5 mm stamping cycle where the male M8 rod end mounts the punch and the opposite end secures a dog for immediate position confirmation.
PCB Edge Guide
Guides circuit boards through a processing station using the anti-rotation through-rod, ensuring the 25 mm bore body fits within tight machine clearances.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X5SB the Right Cylinder?
When sizing this unit, compare its 206.2 N output at 0.5 MPa against adjacent bores: the SDAD20 provides 131.9 N, while the SDAD32 offers 345.6 N. A safe working load is approximately 124 N, enabling a vertical lift of about 10.5 kg with a 2:1 safety margin. This specific configuration includes the S option for magnetic sensing and B option for male M8x1.25 rod threads on both ends, operating via an M5x0.8 port.
The dual-end through-rod prevents rotation and enables dual-end mounting, but remember that a plain cylinder drifts if air pressure drops or the valve centres. The fixed NBR bumper only decelerates near stroke end rather than locking the load. For secure holding without live pressure, integrate an external rod lock or 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 SDAD25X5SB 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, with a proof pressure of 1.5 MPa.
The through-rod resists twisting and allows mounting a tool on one male M8x1.25 end while using the other for a dog or switch. The built-in magnet works with reed or electronic switches, and the short 5 mm stroke minimizes axial footprint.
