Airtac SDAD Double Rod Slim Cylinder SDAD80X70B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X70B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 70mm 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 SDAD80X70B
The AirTAC SDAD80X70B 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 exactly 2267.8 N of push and pull force at 0.5 MPa. This symmetry is ideal for driving loads that require consistent effort on extension and retraction.
This specific SKU includes male M22x1.5 thread on both 25 mm rod ends, allowing direct mounting of tooling. The short body design minimizes axial footprint compared to standard round cylinders. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note this variant lacks a piston magnet and cannot support position sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD80X70B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X70B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 70 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 SDAD80X70B Is Used
Web Guiding Mechanism
Uses the dual male M22x1.5 rod ends to tension and steer material equally in both directions, preventing rotational twist during high-speed line tracking.
Symmetric Lift Station
Raises and lowers a 115 kg platen with matched 2267.8 N force on both the up and down strokes, ensuring smooth vertical travel without sagging.
Dual-End Transfer Arm
Mounts a grip on one end and a mechanical dog on the opposite side, leveraging the compact body to fit within tight automated assembly cells.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X70B the Right Cylinder?
When sizing this unit, compare its 2267.8 N output at 0.5 MPa against adjacent bores. Stepping down to the SDAD63 yields 1401.5 N, while stepping up to the SDAD100 provides 3524.9 N. The 80 mm bore offers a safe working load around 1361 N, which translates to a vertical lift capacity of roughly 115.6 kg when applying a 2:1 safety margin.
The through-rod geometry prevents twisting and permits mounting a work tool on one end with a dog on the opposite side. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the fixed NBR bumper only decelerates the stroke end and does not function as a lock. For load holding, integrate an external rod lock or pilot-operated check valve. This configuration specifies a 70 mm stroke, PT3/8 port, and male M22x1.5 rods on both ends, with 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 SDAD80X70B 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. The theoretical maximum is 463 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not have a piston magnet. You must select the -S option to enable sensing with AirTAC reed or electronic switches. The through-rod design still allows you to mount a physical dog on the opposite end for mechanical detection.
