Airtac SDAD Double Rod Slim Cylinder SDAD25X100
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X100 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 100mm 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 SDAD25X100
The AirTAC SDAD25X100 is a double-acting compact cylinder featuring a 25mm bore and a 100mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 206.2 N at 0.5 MPa in either direction.
A 10mm rod diameter at each end provides strong resistance to twisting, allowing you to mount a work tool on one side and a dog or limit switch on the opposite side. The short body design saves axial mounting depth in tight machinery. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD25X100 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X100 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 100 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 SDAD25X100 Is Used
Gripper Synchronization
Drives opposing gripper jaws where the through-rod geometry ensures perfectly symmetric clamping pressure without rotational drift.
Dual-End Transfer
Mounts a pusher plate on the front rod while the rear rod actuates a mechanical dog to trigger a downstream sensor.
Compact Spot Welding
Fits into shallow welding stations to deliver equal 206.2 N force on extend and retract for consistent electrode pressure.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X100 the Right Cylinder?
When sizing this unit, consider the SDAD20 which yields 131.9 N at 0.5 MPa, or step up to the SDAD32 providing 345.6 N at 0.5 MPa. This SDAD25X100 provides a safe working load of roughly 124 N, or a vertical lift of about 10.5 kg with a 2:1 safety margin. The 100mm stroke sits within the 130mm standard limit for this bore.
This specific SKU lacks the -S magnet, so it cannot accept reed or electronic switches. It features female M5x0.8 rod-end threads and an M5x0.8 air port. Note that a plain cylinder drifts when air is lost or the valve is centered; the NBR bumper only decelerates near stroke end and acts as neither a lock nor a brake. Use an external rod lock or pilot-operated check valve for load holding.
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 SDAD25X100 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.
No, this specific SKU does not include the -S piston magnet. You must select the -S variant to use AirTAC reed or electronic switches for position sensing.
