Airtac SDAD Double Rod Slim Cylinder SDAD80X45B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X45B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm 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 SDAD80X45B
The AirTAC SDAD80X45B 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 you exactly 2267.8 N of push and pull force at 0.5 MPa. This symmetric output is ideal for driving loads that must move with the same authority in both directions.
This specific SKU includes male M22x1.5 thread on both 25 mm rod ends, allowing you to securely mount tooling directly. The short body design drastically reduces axial mounting depth compared to standard round-body cylinders. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, rather than an adjustable air cushion. Note that this variant lacks a piston magnet, so it cannot support magnetic position sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD80X45B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X45B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 45 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M14×1.5 female / M22×1.5 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SDAD80X45B Is Used
Symmetric Lift Station
Drives a vertical lifting platform where equal 2267.8 N push and pull forces prevent sagging on the return stroke, ensuring smooth elevation of heavy jigs.
Anti-Rotation Guide
Handles a precision indexing jaw where the 25 mm through-rod resists twisting torque, maintaining strict alignment without needing external linear bearings.
Dual-End Actuation
Mounts a forming tool on one male M22x1.5 end while the opposite rod end drives a mechanical dog, triggering external limit switches in tight machinery.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X45B the Right Cylinder?
When sizing this unit, compare its 2267.8 N @0.5 MPa capacity against adjacent bores: the SDAD63 provides 1401.5 N, while the SDAD100 offers 3524.9 N. With a safe working load around 1361 N (60% of the 0.5 MPa figure), it can vertically lift approximately 115.6 kg using a 2:1 safety margin. The through-rod geometry inherently resists twisting, enabling you to attach a tool on one end and a dog on the opposite side.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed NBR bumper only decelerates near stroke end and acts as no lock. For load-holding requirements, integrate an external rod lock or pilot-operated check valve. This configuration specifies an 80 mm bore, 45 mm stroke, PT3/8 port, male M22x1.5 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 SDAD80X45B FAQ
The push and pull forces are equal at 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum is 463 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not have a piston magnet. You would need the -S variant to use AirTAC reed or electronic switches. However, the dual male M22x1.5 rod ends still allow mounting external mechanical dogs for position detection.
