Airtac SDAD Double Rod Slim Cylinder SDAD100X30S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X30S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 30mm 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 SDAD100X30S
The AirTAC SDAD100X30S is a double-acting, double-rod compact cylinder featuring a 100mm bore and 30mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber, yielding perfectly symmetric thrust. You get exactly 3524.9 N of force at 0.5 MPa on both extend and retract strokes, preventing twisting during heavy linear motion.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches. The 32mm through-rod allows mounting a work tool on one end while a position dog operates on the opposite side. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, keeping the overall axial footprint short for tight machinery layouts.
Airtac SDAD Double Rod Slim Cylinder SDAD100X30S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X30S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 30 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 SDAD100X30S Is Used
Heavy-Duty Lift Stations
Lifting 179.7 kg vertical loads safely using the symmetric 3524.9 N force, ensuring the platen stays perfectly level without twisting during the rise.
Twin-Tool Machining
Driving a clamping fixture on one rod end while a limit dog triggers an electronic switch on the opposite end, maximizing cycle efficiency in a compact cell.
Symmetric Transfer Arms
Moving heavy pallets with equal push and pull thrust, preventing jerkiness when reversing direction at 30 mm stroke increments.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X30S the Right Cylinder?
When sizing this unit, compare its 3524.9 N @0.5 MPa output with the neighboring SDAD80, which provides 2267.8 N @0.5 MPa. Stepping up to the 100mm bore gives a massive 55% thrust increase over the 80mm option, ensuring high rigidity. A safe working load is approximately 2115 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 179.7 kg with a 2:1 safety margin.
The through-rod geometry inherently resists rotation, making it superior for guiding heavy platens. Remember that a standard cylinder drifts when air is lost or the valve centers; the fixed NBR bumper only decelerates near stroke end and never locks the load. For vertical holding without live pressure, install an external rod lock or pilot-operated check valve. This model features a PT3/8 port, female M18x1.5 rod threads, and the -S magnet option.
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 SDAD100X30S FAQ
The force is equal in both directions due to the double-rod design: 3524.9 N at 0.5 MPa and 4934.8 N at 0.7 MPa. The theoretical maximum is 719 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
Yes, the -S option provides a built-in magnet for AirTAC reed or electronic switches. However, the cylinder will drift if air is lost; the fixed NBR bumper only decelerates the stroke end. For load holding, use an external rod lock or pilot-operated check valve.
