Airtac SDAD Double Rod Slim Cylinder SDAD100X65S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X65S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 65mm 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 SDAD100X65S
The AirTAC SDAD100X65S is a double-acting compact cylinder featuring a 32mm piston rod protruding from both ends of its riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding exactly 3524.9 N of push and pull force at 0.5 MPa. This symmetry is ideal for driving loads that require consistent kinetic energy in both travel directions.
The through-rod geometry inherently resists twisting, allowing you to mount a work tool on one end and a position dog on the opposite side simultaneously. Equipped with a built-in magnet (-S), it supports AirTAC reed or electronic switches via the body sensor grooves. 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 SDAD100X65S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X65S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 65 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M18×1.5 female / M26×1.5 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3525 N |
| 0.7 MPa | 4935 N |
| Max (@1.0 MPa) | 719 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 SDAD100X65S Is Used
Symmetric Platen Lift
Drives a heavy vertical platen requiring identical 3524.9 N push and pull force at 0.5 MPa, ensuring stable ascent and descent without kinetic mismatch.
Twin-Tool Machining Fixture
Uses the anti-rotation through-rod to mount a clamp on one end and a limit dog on the other, maintaining precise alignment during 65mm stroke operations.
Reciprocating Transfer Unit
Pushes and pulls a transfer carriage with equal 4934.8 N force at 0.7 MPa, leveraging the compact riveted body to save axial depth in a tight cell.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X65S the Right Cylinder?
When sizing this 100mm bore model, compare its 3524.9 N @0.5 MPa output with the neighboring SDAD80, which provides 2267.8 N at the same pressure. Stepping up to this larger bore yields a 55% increase in bilateral thrust, crucial if you are moving heavy platens. A safe working load is roughly 2115 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 179.7 kg with a 2:1 safety margin.
This configuration includes a 65mm stroke, PT3/8 air port, and female M18x1.5 rod-end threads on both sides. The through-rod design prevents rotation without external guides, but remember that a plain cylinder drifts when air is lost or the valve centers—the fixed bumper only decelerates near the stroke end. For strict load holding, integrate an external rod lock or pilot-operated check valve.
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 SDAD100X65S FAQ
The double-rod design provides equal force in both directions: 3524.9 N at 0.5 MPa, 4934.8 N at 0.7 MPa, and a theoretical maximum of 719 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
Yes, the -S option includes a built-in magnet for AirTAC reed or electronic switches. However, the cylinder does not hold position on air loss; the fixed NBR bumper only decelerates the stroke end. Use an external rod lock or pilot-operated check valve for load holding.
