Airtac SDAD Double Rod Slim Cylinder SDAD80X35B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X35B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 35mm 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 SDAD80X35B
The AirTAC SDAD80X35B 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 thrust is ideal for balanced gripping or lifting tasks.
This specific SKU includes male M22x1.5 thread on both 25 mm rod ends, allowing direct mounting of tooling on opposite sides. The short body design saves axial depth compared to standard profile cylinders, while the fixed NBR bumpers absorb end-of-stroke shocks. Note that this variant lacks a piston magnet, so position sensing is not supported.
Airtac SDAD Double Rod Slim Cylinder SDAD80X35B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X35B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 35 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 SDAD80X35B Is Used
Web Guiding Mechanism
Utilizes the equal 2267.8 N bidirectional force to tension and steer material rolls smoothly without rotational deflection.
Dual-Side Transfer Arm
Mounts a pusher on one male M22x1.5 rod end and a counterweight on the other to balance horizontal part shuttling.
Symmetric Lifting Jig
Raises and lowers a 115.6 kg fixture with a 2:1 margin, relying on the matching extend and retract thrust for stable vertical travel.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X35B the Right Cylinder?
When sizing this unit, consider the neighbouring bores: stepping down to the SDAD63 yields 1401.5 N at 0.5 MPa, while the larger SDAD100 provides 3524.9 N at 0.5 MPa. The 80 mm bore offers a safe working load of roughly 1361 N, achieving a vertical lift capacity of about 115.6 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting during operation and permits driving a load on one end while using the opposite end for a secondary mechanism. Remember that a plain cylinder drifts when air pressure is lost or the valve is centered; utilize an external rod lock or pilot-operated check valve for strict load holding. This configuration features a 35 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 SDAD80X35B 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, with a theoretical maximum of 463 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
Yes, the through-rod extends from both sides and features male M22x1.5 threads on each end. This allows you to drive a tool on one side while attaching a dog or secondary fixture on the opposite end, while the rod itself resists twisting.
