Airtac SDAD Double Rod Slim Cylinder SDAD40X15B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X15B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 15mm 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 SDAD40X15B
The AirTAC SDAD40X15B is a double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies each chamber equally, the annular area remains constant, delivering an identical push and pull force of 527.8 N at 0.5 MPa. This symmetry is highly advantageous when driving rigid loads that require balanced bi-directional thrust.
Designed for tight spaces, the short body minimizes axial mounting depth where standard cylinders fail to fit. This specific SKU features male M14x1.5 thread on both 16 mm rod ends, allowing direct attachment of tooling. It lacks a piston magnet, so position sensing is not supported on this base unit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD40X15B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X15B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 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 SDAD40X15B Is Used
Symmetric Pinching
Drives an opposing gripper where the 527.8 N equal force ensures balanced clamping pressure on both extend and retract strokes.
Dual-End Transfer
Mounts a male M14x1.5 tool on one end and a mechanical dog on the opposite end to trip external limit switches.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X15B the Right Cylinder?
When sizing this unit, compare its 527.8 N output at 0.5 MPa against adjacent bores. Dropping down to the SDAD32 yields 345.6 N, while stepping up to the SDAD50 provides 824.7 N. The 15 mm stroke operates efficiently within the 30-500 mm/s speed range.
The through-rod geometry inherently resists twisting, making it perfect for dual-end mounting where one side drives a tool and the opposite side handles a secondary task. Remember that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not lock the load. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration includes the B option for male M14x1.5 rods and uses a PT1/8 port.
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 SDAD40X15B FAQ
The push and pull forces are identical due to the double-rod design. 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.
Yes, the through-rod protrudes from both sides, allowing you to drive a tool on one end while using the opposite end for secondary operations. This specific B-code variant features male M14x1.5 threads on both 16 mm rod ends for direct mounting.
