Airtac SDAD Double Rod Slim Cylinder SDAD80X120SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X120SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 120mm 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 SDAD80X120SB
The AirTAC SDAD80X120SB is a double-acting, double-rod compact cylinder engineered for symmetric actuation. Because a 25 mm rod exits both ends of the riveted body, the annular piston area is identical in both chambers, yielding an equal push and pull force of 2267.8 N at 0.5 MPa. This geometric balance prevents twisting and ensures stable motion for heavy guided loads.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, along with male M22x1.5 rod threads on both ends. The short body footprint saves axial mounting depth compared to standard round-body options. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X120SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X120SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 120 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 SDAD80X120SB Is Used
Elevator Stage Lift
Raises and lowers a 115 kg vertical platform with equal force both ways, using the male M22x1.5 rods to secure the carriage while maintaining a short axial profile.
Transfer Shuttle
Drives a symmetric parts shuttle where the through-rod resists rotational twist, allowing a reed switch to track position on the rear end without interrupting the front tool.
Heavy Duty Clamping
Clamps thick steel workpieces with 2267.8 N of force at 0.5 MPa, relying on the fixed NBR bumper to absorb the end shock of the 120 mm stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X120SB the Right Cylinder?
When sizing this unit, compare its 2267.8 N output at 0.5 MPa against neighboring bores. Stepping down to the SDAD63 provides 1401.5 N, while stepping up to the SDAD100 yields 3524.9 N. Based on the 80 mm bore, a safe working load is approximately 1361 N (60% of the 0.5 MPa figure), allowing a vertical lift of roughly 115.6 kg with a 2:1 safety margin.
The through-rod design allows you to mount a tool on one end and a position dog on the opposite side simultaneously. Remember that a plain cylinder drifts when air is lost or the valve centers—the fixed 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 model features an 80 mm bore, 120 mm stroke, PT3/8 port, an S magnet, and male B rod threads.
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 SDAD80X120SB FAQ
The push and pull forces are equal because the rod occupies both chambers. It generates 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes. The double-rod design features a 25 mm through-rod with male M22x1.5 threads on both ends, allowing you to drive a tool on one side while mounting an AirTAC reed or electronic switch on the opposite end to read position.
