Airtac SDAD Double Rod Slim Cylinder SDAD80X30SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X30SB 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 SDAD80X30SB
The AirTAC SDAD80X30SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies each chamber equally, the annular area remains constant, delivering 2267.8 N of force at 0.5 MPa in both extend and retract directions. This symmetric output is ideal for balanced actuation tasks.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, the unit provides reliable position feedback. The -B option specifies male M22x1.5 rod threads on both ends, allowing direct mounting of tooling. A fixed NBR bumper decelerates the stroke ends within the 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD80X30SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X30SB |
|---|---|
| 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 SDAD80X30SB Is Used
Symmetric Lifting Jig
Drives a vertical lift platform where equal 2267.8 N push and pull forces prevent binding during heavy component elevation.
Dual-End Transfer Unit
Utilizes the male M22x1.5 threads on both rod ends to push a part forward while a magnetic switch tracks the exact 30 mm stroke position.
Anti-Rotation Guide
Employs the through-rod to resist twisting during precision clamping, maintaining strict alignment without external linear bearings.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X30SB the Right Cylinder?
When sizing this 80 mm bore model, consider the adjacent options: the smaller SDAD63 yields 1401.5 N at 0.5 MPa, while the larger SDAD100 provides 3524.9 N. This SDAD80X30SB strikes a middle ground, offering a safe working load of roughly 1361 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity of approximately 115.6 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and permits driving a tool on one end while mounting a dog on the opposite side. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed NBR bumper only decelerates near stroke end and does not lock the load. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration includes the PT3/8 port, male M22x1.5 rod threads, and the piston 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 SDAD80X30SB FAQ
Because the double-rod design provides equal annular area in both directions, push and pull forces are identical: 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa.
No, a plain cylinder drifts when air is lost or the valve centers. The fixed NBR bumper only decelerates the stroke end and does not act as a brake. For load holding, you must add an external rod lock or pilot-operated check valve.
