Airtac SDAD Double Rod Slim Cylinder SDAD100X35SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X35SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 35mm 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 SDAD100X35SB
The AirTAC SDAD100X35SB is a double-acting, double-rod compact cylinder engineered for rigorous pneumatic applications. Because the 32mm through-rod occupies both internal chambers, the effective annular piston area remains identical in either direction. This geometry ensures push and pull forces match exactly, yielding 3524.9 N of thrust and retraction at 0.5 MPa, scaling to 4934.8 N at 0.7 MPa.
Featuring a space-saving riveted body, this unit saves axial mounting depth where larger profile cylinders cannot fit. The integrated piston magnet enables position sensing via reed or electronic switches. A fixed NBR bumper decelerates the 35mm stroke at both ends, while the male M26x1.5 threads on both rod ends provide robust tool mounting options.
Airtac SDAD Double Rod Slim Cylinder SDAD100X35SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X35SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 35 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 SDAD100X35SB Is Used
Heavy-Duty Pressing
Applies 4934.8 N at 0.7 MPa for stamping or crimping operations where identical extend and retract forces prevent asymmetric tool wear.
Dual-End Transfer
Uses the anti-rotation through-rod to push a part on one end while a position dog triggers a sensor on the opposite end simultaneously.
Vertical Lift Jig
Lifts vertical loads up to 179.7 kg with a 2:1 safety margin, relying on the male M26x1.5 threads for secure heavy fixture mounting.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X35SB the Right Cylinder?
When sizing this 100mm bore unit, consider the SDAD80 which provides 2267.8 N at 0.5 MPa for lighter loads, or step up to this model for heavy-duty symmetric force. The through-rod design inherently resists twisting, allowing you to drive a mechanism on one end while mounting a dog or switch on the opposite side. Computed sizing indicates a safe working load around 2115 N (60% of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 179.7 kg with a 2:1 safety margin.
This configuration includes the -S magnet for AirTAC reed or solid-state switches and the -B option for male M26x1.5 rod threads on both ends. The pneumatic port is PT3/8. Note that a plain cylinder does not hold position upon air loss or valve centering; the piston drifts and the fixed bumper only decelerates near the stroke end. For load holding without live pressure, install 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 SDAD100X35SB 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 through-rod resists twisting and allows dual-end mounting, such as driving a tool on one side and a sensor dog on the other. The -B option provides male M26x1.5 threads on both rod ends for robust fixture attachment.
