Airtac SDAD Double Rod Slim Cylinder SDAD25X90
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X90 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 90mm 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 SDAD25X90
The AirTAC SDAD25X90 is a double-acting compact cylinder featuring a 25 mm bore and a 90 mm stroke. A piston rod extends from both ends of the riveted body, creating identical annular areas on each side. This geometry ensures push and pull forces match exactly at 206.2 N when operating at 0.5 MPa, making it ideal for symmetric load handling.
With a 10 mm rod diameter and an M5x0.8 air port, this unit integrates easily into tight machinery. The through-rod design inherently resists twisting during operation. 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 SDAD25X90 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X90 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 90 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 SDAD25X90 Is Used
Symmetric Transfer Arms
Drives a pick-and-place arm where the matching 206.2 N extend and retract forces prevent jerky movements during component transfer.
Anti-Twist Guiding Jigs
Uses the through-rod geometry to maintain strict alignment on a 90 mm stroke, resisting rotational torque on precision clamping jigs.
Dual-End Sealing Stations
Mounts a sealing head on the front rod and a cam for a mechanical valve on the rear, saving space in compact packaging machinery.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X90 the Right Cylinder?
Choosing this 25 mm bore model provides a safe working load of roughly 124 N, calculated at 60 percent of the 0.5 MPa output. If your application requires less force, the smaller SDAD20 yields 131.9 N at 0.5 MPa, whereas stepping up to the SDAD32 provides 345.6 N. This specific SKU lacks a piston magnet, so position sensing is unavailable unless you select the -S variant for reed or electronic switches.
The dual-end rod allows mounting a tool on one side and a dog on the opposite end simultaneously. Remember that a standard cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift. For secure load holding without live pressure, install 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 SDAD25X90 FAQ
The push and pull forces are identical because the rod exits both ends. It generates 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.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S option code. The dual-end through-rod still allows you to mount a mechanical dog for external sensing.
