Airtac SDAD Double Rod Slim Cylinder SDAD40X10B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X10B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 10mm 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 SDAD40X10B
The AirTAC SDAD40X10B 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, giving exactly 527.8 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balancing loads without tweaking pressure regulators.
This specific SKU uses male M14x1.5 threads on the 16 mm rods at both ends for direct tool mounting. The short 10 mm stroke keeps the overall footprint tight, while the fixed NBR bumper absorbs end-of-stroke shock without requiring adjustment.
Airtac SDAD Double Rod Slim Cylinder SDAD40X10B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X10B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 10 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SDAD40X10B Is Used
Web Guiding
Drives a steering roller on one end while the opposite rod mounts a tracking dog, using the equal 527.8 N bidirectional force to nudge material without rotational play.
Transfer Chute Gate
Opens and closes a diverter flap where the male M14x1.5 threads secure the linkage, benefiting from the compact 10 mm stroke to minimize axial mounting depth.
Sealing Jaw Press
Applies symmetric clamping pressure via both rod ends to hold a carton square, relying on the fixed NBR bumper to soften the impact at the 10 mm stroke limit.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X10B the Right Cylinder?
When sizing this unit, stepping down to the SDAD32 yields 345.6 N at 0.5 MPa, whereas moving up to the SDAD50 provides 824.7 N. Based on the 527.8 N output, a safe working load is roughly 317 N (about 60 percent capacity), translating to a vertical lift of approximately 26.9 kg with a 2:1 safety margin. The through-rod geometry prevents twisting and allows driving a tool on one end while using the opposite end for a secondary mechanism. Note that this non-magnet version cannot host reed or electronic switches, and the male M14x1.5 rod ends require matching female threads on your fixtures. Furthermore, the cylinder will drift if air pressure is lost, so add an external rod lock or pilot-operated check valve if you need strict 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 SDAD40X10B FAQ
The push and pull forces are equal because the rod exits both ends. It generates 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU lacks the -S piston magnet and cannot accept reed or electronic switches. You would need the -S variant for position sensing. The through-rod design still allows you to mount a mechanical dog or tool on the opposite end.
