Airtac SDAD Double Rod Slim Cylinder SDAD80X30B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X30B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 30mm 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 SDAD80X30B
The AirTAC SDAD80X30B is a double-acting compact cylinder featuring a piston rod exiting both ends of its riveted body. Because the rod occupies each chamber, the annular area matches on extend and retract, delivering an identical push and pull force of 2267.8 N at 0.5 MPa. This symmetric output is a major advantage when driving rigid loads that require balanced resistance in both travel directions.
Equipped with male M22x1.5 rod threads on both ends, this specific SKU allows direct mounting of tooling on one side while utilizing the opposite end for a secondary mechanism. The through-rod geometry inherently resists mechanical twist, and the short body design saves valuable axial space compared to conventional cylinders. It relies on a fixed NBR bumper at each stroke end to absorb shock, yielding a safe working load of roughly 1361 N for a 2:1 safety factor.
Airtac SDAD Double Rod Slim Cylinder SDAD80X30B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X30B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 30 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 SDAD80X30B Is Used
Web Guiding Mechanism
Utilizes the anti-rotation through-rod to steer material evenly, maintaining precise alignment without twisting under the 2267.8 N bidirectional force.
Dual-End Transfer Pusher
Mounts a drive dog on one male M22x1.5 end and a secondary actuator on the opposite, synchronizing two conveyor lanes in a compact footprint.
Balanced Lift Station
Lifts a 115.6 kg vertical load with a 2:1 safety margin, relying on equal push and pull forces to prevent sagging during upward and downward travel.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X30B the Right Cylinder?
When sizing this unit, consider the neighboring bores: the SDAD63 provides 1401.5 N at 0.5 MPa, while the SDAD100 offers 3524.9 N. The SDAD80X30B bridges that gap perfectly with 2267.8 N, yielding a vertical lift capacity of approximately 115.6 kg with a 2:1 margin. The through-rod design prevents rotation and enables dual-end mounting, but remember a plain cylinder drifts when air is lost or the valve centers. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
This configuration includes the B option, meaning the 25 mm rods feature male M22x1.5 threads at both ends instead of the default female M14x1.5. The air port is PT3/8, and the standard 30 mm stroke operates within the 130 mm maximum limit. Note that this SKU lacks the S magnet code, so it cannot accept AirTAC reed or electronic switches for position sensing.
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 SDAD80X30B FAQ
The double-rod design provides equal force in both directions: 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.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one male M22x1.5 end while using the other for a secondary task. The fixed NBR bumpers decelerate the stroke ends, but for load holding you need an external rod lock.
