Airtac SDAD Double Rod Slim Cylinder SDAD80X90SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X90SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 90mm 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 SDAD80X90SB
The AirTAC SDAD80X90SB 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 essential for tooling that must drive and retract with equal authority.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, and male-thread rods (-B) measuring M22x1.5 on both ends, this unit simplifies dual-end mounting. The short body design saves axial depth compared to conventional cylinders, while the fixed NBR bumper decelerates the stroke ends without requiring adjustment.
Airtac SDAD Double Rod Slim Cylinder SDAD80X90SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X90SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 90 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 SDAD80X90SB Is Used
Symmetric Lift Station
Drives a vertical lift platform requiring 2267.8 N of equal force in both directions to raise and lower 115.6 kg loads smoothly without sagging.
Dual-End Transfer Mechanism
Uses the male M22x1.5 threads on both rod ends to push a part on one side while triggering an electronic switch dog on the opposite end simultaneously.
Anti-Rotation Straightener
Resists twisting torque during heavy-duty metal flattening tasks, keeping the tooling perfectly aligned thanks to the 25 mm through-rod design.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X90SB the Right Cylinder?
When sizing this 80 mm bore, compare it directly with its neighbors: the SDAD63 provides 1401.5 N at 0.5 MPa, while the SDAD100 offers 3524.9 N. The SDAD80X90SB sits perfectly in the middle at 2267.8 N, yielding a safe working load of roughly 1361 N (about 60 percent of capacity) and a vertical lift capability of approximately 115.6 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting and lets you mount a dog on the opposite end from your tool. Remember that a plain cylinder drifts when air is lost or the valve centers—the fixed bumper only decelerates near stroke end, so add an external rod lock or pilot-operated check valve for load holding. This configuration specifies a 90 mm stroke, PT3/8 port, male M22x1.5 rod threads, and a piston magnet for 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 SDAD80X90SB FAQ
Because the double-rod design creates equal annular areas, 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 in both directions.
Yes, the through-rod exits both sides with male M22x1.5 threads, allowing you to drive a tool on one end and mount a switch dog on the other. The -S magnet enables position sensing with AirTAC reed or electronic switches.
