Airtac SDAD Double Rod Slim Cylinder SDAD12X45B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X45B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm 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 SDAD12X45B
The AirTAC SDAD12X45B is a compact double-acting cylinder featuring a 12mm bore and 45mm stroke, with piston rods extending from both ends. Because a rod occupies each chamber, the annular area is identical on extend and retract, yielding an equal push and pull force of 42.4 N at 0.5 MPa. This symmetry is ideal for driving loads that require consistent kinetic energy in both directions.
The through-rod geometry inherently resists twisting, providing stable guidance without external linear bearings. Its short riveted body minimizes axial mounting depth where a larger profile cylinder will not fit. Equipped with male M5x0.8 threads on both rod ends, this specific SKU lacks a piston magnet and therefore cannot support magnetic sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD12X45B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X45B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 45 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø12mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 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 SDAD12X45B Is Used
Micro-Grip Transfer
Drives a small gripper on one end and a dog on the opposite end, using the 42.4 N equal force to move delicate electronic components symmetrically.
Anti-Rotation Pusher
The through-rod resists twisting during vertical pressing tasks, ensuring a 12mm bore aligns contacts perfectly without lateral drift.
Lab Sample Ejector
Uses the male M5x0.8 rods to push and pull a test tray with identical 59.4 N at 0.7 MPa, maintaining stable kinetics in compact analytical equipment.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X45B the Right Cylinder?
When sizing this unit, compare its 42.4 N output at 0.5 MPa against adjacent bores. Stepping up to the SDAD16 increases force to 86.4 N, while stepping down to a smaller bore drops below practical limits for most loads. For this 12mm bore, a safe working load is approximately 25 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 2.2 kg with a 2:1 safety margin.
The dual-end male M5x0.8 rods allow mounting a tool on one side and a dog on the other. Note that a plain cylinder does not hold position on air loss or valve centering; the piston drifts. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your M5x0.8 port connection and approach speed before checkout.
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 SDAD12X45B FAQ
Because the double-rod design provides equal annular area in both directions, push and pull forces are identical: 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a theoretical maximum of 9 kgf at 1.0 MPa.
No, this specific SKU does not have a piston magnet, so it cannot support magnetic sensing. The -S variant adds a magnet for AirTAC reed or electronic switches. The dual male M5x0.8 rods do allow mechanical dog triggering on the opposite end.
