Airtac SDAD Double Rod Slim Cylinder SDAD80X15B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X15B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm 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 SDAD80X15B
The AirTAC SDAD80X15B 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, delivering an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetry is highly advantageous for loads requiring consistent kinetic energy regardless of travel direction.
Equipped with male M22x1.5 threads on both 25 mm rod ends, this unit allows direct mounting of tooling on one side and a dog or mechanism on the opposite side. The short footprint saves axial depth compared to conventional cylinders, while end-of-stroke deceleration is handled by fixed NBR bumpers. Note this SKU lacks a piston magnet, so position sensing is not supported.
Airtac SDAD Double Rod Slim Cylinder SDAD80X15B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X15B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 15 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 SDAD80X15B Is Used
Guided Lift Stations
The equal 2267.8 N force and anti-twist through-rod keep heavy vertical lifting platforms perfectly stable during rapid up and down cycles.
Dual-End Forming
Mount a forming tool on one male M22x1.5 rod end and a synchronised clamp on the opposite side to execute simultaneous metalworking tasks.
Symmetric Diverters
Drive a conveyor sorting gate from either side without force imbalance, ensuring products are pushed smoothly without rotational binding.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X15B the Right Cylinder?
When sizing this 80 mm bore, evaluate the neighbouring capacities: stepping down to SDAD63 yields 1401.5 N at 0.5 MPa, whereas moving up to SDAD100 provides 3524.9 N. For this model, a safe working load is approximately 1361 N (about 60 percent of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 115.6 kg with a 2:1 safety margin. The through-rod geometry inherently resists rotation, making it excellent for guided assemblies.
This configuration includes the B option, meaning both rod ends feature male M22x1.5 threads, and the air supply connects via PT3/8 ports. Remember that a standard cylinder drifts when air is removed or the valve is centered, as the NBR bumper only decelerates the stroke end and does not act as a lock. For suspended loads, integrate an external rod lock or pilot-operated check valve. Operating speed ranges from 30-500 mm/s.
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 SDAD80X15B FAQ
The push and pull forces are equal because the rod exits both ends. It generates 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa, with a theoretical maximum of 463 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
The through-rod prevents twisting under offset loads and allows you to mount tooling on one end while driving a mechanism from the opposite end. This specific B variant features male M22x1.5 threads on both sides for easy attachment.
