Airtac SDAD Double Rod Slim Cylinder SDAD80X75SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X75SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 75mm 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 SDAD80X75SB
The AirTAC SDAD80X75SB is a compact double-acting cylinder featuring a piston rod exiting both ends of its riveted body. Because the rod occupies each chamber equally, the annular area remains constant, delivering identical push and pull forces of 2267.8 N at 0.5 MPa. This symmetric thrust is highly advantageous for manipulating heavy loads without directional force mismatch.
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 threads on the 25 mm diameter rods at both ends. Its space-saving footprint fits where standard round bodies cannot, while end-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X75SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X75SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 75 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 SDAD80X75SB Is Used
Symmetric Lift Station
Lifts 115.6 kg platens vertically using the equal 2267.8 N bidirectional force, ensuring smooth ascent and descent without thrust imbalance.
Twin-Side Machining Jig
Drives a machining head on one male M22x1.5 rod end while a dog fixture rides the opposite end, leveraging the anti-rotation geometry for precise milling.
Dual-End Transfer Arm
Pushes a transfer carriage 75 mm while simultaneously triggering a reed switch on the rear rod, saving axial space in tight conveyor routing.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X75SB the Right Cylinder?
When sizing this 80 mm bore, verify your force margins against adjacent models. Dropping to the SDAD63 yields 1401.5 N at 0.5 MPa, whereas stepping up to the SDAD100 provides 3524.9 N. For the SDAD80X75SB, a safe working load is approximately 1361 N (60% of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 115.6 kg with a 2:1 safety margin.
The through-rod design inherently resists twisting, allowing you to mount tooling on one end and a position dog on the opposite side. Confirm your setup requires PT3/8 air ports and 75 mm of travel. Remember that a plain cylinder drifts when air is lost or the valve centers; utilize an external rod lock or pilot-operated check valve for strict load holding.
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 SDAD80X75SB FAQ
The push and pull forces are equal because of the double-rod design. 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.
Yes, the male M22x1.5 threaded rods exit both ends, allowing you to mount a tool on one side and a switch dog on the other. The through-rod also resists twisting, though end stopping relies on a fixed NBR bumper, not an adjustable cushion.
