Airtac SDAD Double Rod Slim Cylinder SDAD25X50B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X50B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 50mm 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 SDAD25X50B
The AirTAC SDAD25X50B is a double-acting, double-rod compact cylinder featuring a 25 mm bore and 50 mm stroke. Because the piston rod exits both ends, the annular area remains identical in each chamber, delivering an equal push and pull force of 206.2 N at 0.5 MPa. This symmetric output is ideal for balanced load driving.
The through-rod geometry inherently resists twisting, while the short riveted body minimizes axial mounting depth. This specific SKU includes male M8x1.25 thread rods on both ends and lacks a piston magnet. End-of-stroke deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions.
Airtac SDAD Double Rod Slim Cylinder SDAD25X50B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X50B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 50 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 SDAD25X50B Is Used
Symmetric Transfer
Drives a pick-and-place head with equal 206.2 N force extending and retracting, ensuring stable part transfer without momentum shifts.
Anti-Twist Guiding
The dual through-rod resists rotational torque during tight tolerance pressing, keeping the tool plumb without external linear bearings.
Dual-End Actuation
Mounts a work fixture on the male M8x1.25 rod end while the opposite side drives a mechanical dog for external cam tracking.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X50B the Right Cylinder?
When sizing this actuator, stepping down to the SDAD20 yields 131.9 N at 0.5 MPa, while stepping up to the SDAD32 provides 345.6 N at 0.5 MPa. The 25 mm bore offers a computed safe working load of roughly 124 N and a vertical lift capacity of about 10.5 kg with a 2:1 safety margin. The through-rod design allows mounting a tool on one end and a dog on the opposite end simultaneously.
This configuration features male M8x1.25 rod threads, an M5x0.8 air port, and no piston magnet, meaning magnetic switches cannot be used. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the NBR bumper only decelerates the stroke end and does not lock the load. For secure load holding, 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 SDAD25X50B FAQ
The push and pull forces are equal because the rod occupies both chambers. It generates 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in both directions. The theoretical maximum is 42 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
This specific SKU lacks the -S magnet, so it cannot accept reed or electronic switches. Additionally, it does not hold position on air loss; the piston drifts and the fixed NBR bumper only decelerates near stroke end. Use an external rod lock for load holding.
