Airtac SDAD Double Rod Slim Cylinder SDAD12X45SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X45SB 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 SDAD12X45SB
The AirTAC SDAD12X45SB is a compact double-acting cylinder featuring a 12 mm bore and 45 mm stroke. Its through-rod design exits both ends of the riveted body, ensuring the annular area remains identical on extend and retract. This geometry yields exactly 42.4 N of force at 0.5 MPa in both directions, preventing asymmetric load behavior.
Equipped with a male M5x0.8 thread on both rod ends and a built-in magnet, this unit supports reed or electronic switches. The short body footprint minimizes axial mounting depth. End-of-stroke deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD12X45SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X45SB |
|---|---|
| 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 SDAD12X45SB Is Used
Micro-Gripper Actuation
Drives a small parallel gripper where the 42.4 N equal push and pull force ensures symmetric clamping on delicate electronic components.
Anti-Rotation Guide
The twin 6 mm rods resist twisting during vertical pressing tasks, maintaining precise alignment without external guides.
Dual-End Timing Mechanism
Mounts a pick-place tool on one end and a magnetic dog on the opposite end to trigger a reed switch at mid-stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X45SB the Right Cylinder?
When sizing this 12 mm bore actuator, the adjacent SDAD16 offers a higher 86.4 N at 0.5 MPa if you need greater thrust. Downward from 12 mm, you are at the series minimum. The through-rod resists twisting and permits driving a tool on one end while mounting a dog on the opposite side. A safe working load is roughly 25 N, allowing a vertical lift of about 2.2 kg with a 2:1 margin.
This SDAD12X45SB configuration includes the S magnet for sensing and B male M5x0.8 rod threads. It uses an M5x0.8 port. Note that a plain cylinder drifts when air is lost; 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 SDAD12X45SB FAQ
Because the rod occupies both chambers, force is identical in both directions: 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.
The through-rod provides anti-rotation resistance and allows you to mount a tool on one end and a sensor target on the other. The male M5x0.8 threads on both ends simplify fixture attachment.
