Airtac SDAD Double Rod Slim Cylinder SDAD40X45
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X45 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm 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 SDAD40X45
The AirTAC SDAD40X45 is a compact double-acting 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 you exactly 527.8 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balanced tooling.
The 16 mm piston rod resists twisting during operation and allows you to mount a work tool on one end while driving a dog or mechanism on the opposite side. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot support position sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD40X45 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X45 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 45 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 SDAD40X45 Is Used
Guided Strip Peeling
Drives a peeling blade on one rod end while the opposite end moves a depth gauge, relying on the 527.8 N equal force to maintain consistent material removal without twisting.
Symmetric Transfer Arm
Powers a dual-sided pick-and-place arm where the through-rod ensures parallel movement, utilizing the 45 mm stroke to shuttle components between stations smoothly.
Balanced Lift Jig
Lifts a 26.9 kg vertical payload using the dual-end outputs, taking advantage of the anti-rotation properties to keep the jig perfectly level during elevation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X45 the Right Cylinder?
When sizing this unit, compare its 527.8 N output at 0.5 MPa against adjacent bores: the SDAD32 provides 345.6 N, while the SDAD50 yields 824.7 N.
The through-rod geometry prevents rotation and enables dual-end mounting, but remember the fixed bumper only decelerates near stroke end and does not hold the load. If air pressure drops, the piston will drift; use an external rod lock or pilot-operated check valve for load holding. This configuration specifies a 40 mm bore, 45 mm stroke, PT1/8 port, female M8x1.25 rod threads, and no magnet.
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 SDAD40X45 FAQ
The SDAD40X45 generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 108 kgf at 1.0 MPa. Because it is a double-rod cylinder, the push and pull forces are exactly equal in both directions. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod design allows you to attach tooling on one end and a dog or mechanism on the opposite end while resisting rotational twist. Note that this specific SKU does not have a piston magnet; you must select the -S variant to use reed or electronic switches for position sensing.
