Airtac SDAD Double Rod Slim Cylinder SDAD100X120S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X120S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 120mm 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 SDAD100X120S
The AirTAC SDAD100X120S is a double-acting, double-rod compact cylinder featuring a 100mm bore and 120mm stroke. Because the 32mm piston rod exits both ends of the riveted body, the annular area is identical in each chamber, yielding exactly 3524.9 N of force at 0.5 MPa in both extend and retract directions. This symmetric thrust is ideal for heavy loads requiring consistent motion without twisting.
Designed to save axial mounting depth, the short body integrates a fixed NBR bumper at each end to decelerate the stroke end rather than relying on an adjustable air cushion. The built-in S magnet enables position detection using an AirTAC reed or electronic switch. Operating pressure spans 0.15 to 1.0 MPa, with a safe working load around 2115 N, ensuring robust performance in tight machinery footprints.
Airtac SDAD Double Rod Slim Cylinder SDAD100X120S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X120S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 120 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 SDAD100X120S Is Used
Heavy-Duty Pressing
Utilizes the 3524.9 N equal bidirectional force to press heavy components securely without rotational deflection.
Symmetric Lift Stations
Employs the dual-end rod to lift and lower platforms evenly, ensuring balanced vertical movement and stable load handling.
Multi-Tool Actuation
Mounts a primary work tool on one rod end and a dog for a reed or electronic switch on the opposite end to sequence operations.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X120S the Right Cylinder?
When sizing this model, consider the neighboring bores: stepping down to SDAD80 provides 2267.8 N at 0.5 MPa, while the SDAD100X120S offers a substantial 3524.9 N. The through-rod geometry resists rotation and allows dual-end mounting, letting you drive a tool on one side while tracking position with a switch on the other. Confirm the PT3/8 port, female M18x1.5 rod-end threads, and the included S magnet for your sensing requirements.
Remember that a plain cylinder does not hold its load on air loss or when the valve is centered, as the piston drifts and the fixed NBR bumper only decelerates near the stroke end. For secure vertical load holding—such as lifting approximately 179.7 kg with a 2:1 margin—you must add an external rod lock or a 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 SDAD100X120S FAQ
The force is equal in both directions due to the double-rod design: 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 maximum operating pressure is 1.0 MPa.
No, the piston drifts if air is lost or the valve is centered, as the fixed NBR bumper only decelerates the stroke end. For secure vertical load holding, you must install an external rod lock or a pilot-operated check valve.
