Airtac SDAD Double Rod Slim Cylinder SDAD25X45H
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X45H is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 45mm 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 SDAD25X45H
The AirTAC SDAD25X45H is a double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, delivering an equal push and pull force of 206.2 N at 0.5 MPa. This symmetry is highly advantageous for loads requiring perfectly balanced actuation.
This specific H variant utilizes a fluororubber (FKM) seal for enhanced thermal stability and oil resistance. The 10 mm piston rod resists twisting during operation, while the short body design minimizes axial mounting depth. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD25X45H Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X45H |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 45 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 SDAD25X45H Is Used
Gripper Synchronization
Drives opposing gripper jaws where the equal 206.2 N extend and retract forces prevent twisting of delicate electrical components during pickup.
Dual-End Transfer
Mounts a workpiece pusher on the front rod and a cam dog on the rear rod, allowing a mechanical limit switch to confirm the 45 mm travel externally.
Heat-Resistant Sealing
Applies consistent 288.6 N sealing pressure at 0.7 MPa on a packaging flap, leveraging the FKM seals for operations near heat tunnels.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X45H the Right Cylinder?
When sizing this unit, consider the neighboring bores: the SDAD20 provides 131.9 N at 0.5 MPa, while the SDAD32 offers 345.6 N. The through-rod geometry allows you to mount a tool on one end and a dog on the opposite end simultaneously.
This configuration specifies a 45 mm stroke, an M5x0.8 air port, and female M5x0.8 rod-end threads. Note that this SKU lacks a piston magnet, so magnetic switches cannot be used. Furthermore, a standard cylinder cannot hold a load if air pressure is lost; the piston will drift. For 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 SDAD25X45H FAQ
The push and pull forces are equal because of the double-rod design. 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, so it cannot accept reed or electronic switches. You would need the -S option variant to utilize the built-in body sensor grooves for position detection.
