Airtac SDAD Double Rod Slim Cylinder SDAD80X65B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X65B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 65mm 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 SDAD80X65B
The AirTAC SDAD80X65B 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 balancing heavy loads without tweaking regulator pressures.
Equipped with male M22x1.5 rod threads on both ends, this 80 mm bore unit saves axial mounting depth compared to standard profile bodies. The fixed NBR bumper decelerates the 65 mm stroke at the ends, but note this specific SKU lacks a piston magnet, so position sensing is not supported without the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X65B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X65B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 65 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 SDAD80X65B Is Used
Elevator Stage Lifting
Lifts a 115 kg vertical platform using the 2267.8 N bidirectional force, relying on the through-rod to prevent platform twist during ascent.
Dual-Side Clamping Jig
Clamps a heavy workpiece from both ends simultaneously, utilizing the male M22x1.5 threads to secure custom jaws on each side.
Pallet Transfer Pusher
Shoves heavy pallets along a line where the compact riveted body fits into tight axial spaces between roller sections.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X65B the Right Cylinder?
When sizing this model, the SDAD63 provides 1401.5 N at 0.5 MPa, while stepping up to the SDAD100 yields 3524.9 N. The 80 mm bore hits a sweet spot, offering a safe working load of roughly 1361 N (about 60 percent of the 0.5 MPa rating) and a vertical lift capacity near 115.6 kg with a 2:1 safety margin.
The through-rod geometry resists twisting during operation and allows you to mount a tool on one end and a dog on the opposite side. Remember that a plain cylinder drifts when air is lost or the valve is centered, so add an external rod lock or pilot-operated check valve for load holding. This configuration includes the B option for male M22x1.5 rod threads, uses a PT3/8 port, and operates without a 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 SDAD80X65B FAQ
The push and pull forces are equal because of the double-rod design. It generates 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa in both directions. The theoretical maximum is 463 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a mechanism on one end while attaching a dog or secondary tool on the other. This specific B-code model features male M22x1.5 threads on both rod ends for secure mounting.
