Airtac SDAD Double Rod Slim Cylinder SDAD100X20B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X20B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 20mm 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 SDAD100X20B
The AirTAC SDAD100X20B is a double-acting compact cylinder featuring a 100mm bore and a 20mm stroke, engineered with twin piston rods exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area remains identical, yielding exactly 3524.9 N of force at 0.5 MPa on both extend and retract strokes. This symmetric output is essential for applications demanding balanced load handling without drift bias.
Equipped with male M26x1.5 rod threads on both ends, this specific SKU omits a piston magnet, meaning magnetic position sensing is not supported. The through-rod geometry inherently resists twisting, allowing you to mount a heavy work tool on one end while driving a mechanism from the opposite side. Operating between 0.15 and 1.0 MPa, it relies on a fixed NBR bumper to decelerate at stroke limits rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD100X20B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X20B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 20 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 SDAD100X20B Is Used
Heavy-Duty Pressing
Applies 3524.9 N of equal force in both directions to seat bearings or stamp components, utilizing the male M26x1.5 rods for secure tool mounting.
Symmetric Lifting Jig
Lifts 179.7 kg vertical payloads with a 2:1 margin, relying on the anti-rotation through-rod to prevent load twisting during elevation.
Dual-End Transfer
Drives a transfer clamp on one end while a mechanical dog operates on the opposite side, maximizing the 20mm short stroke for rapid part shifting.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X20B the Right Cylinder?
When sizing this unit, compare its 3524.9 N output at 0.5 MPa against the neighboring SDAD80, which provides 2267.8 N. Stepping up to the 100mm bore offers a massive 55% increase in thrust over the 80mm variant, making it the optimal choice when your payload approaches 2115 N safe working load (about 60% of the 0.5 MPa capacity). For vertical lifts, expect a secure 179.7 kg capacity with a 2:1 safety margin. This model uses a PT3/8 port and features male M26x1.5 threads on both rods.
The through-rod design prevents rotation and enables dual-end mounting, but remember that a standard cylinder cannot hold a load if air pressure drops or the valve centers—the piston will drift. For load-holding security, integrate an external rod lock or pilot-operated check valve. The fixed NBR bumpers absorb end-of-stroke shock, but for high-energy cycles, consider adding external shock absorbers.
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 SDAD100X20B FAQ
The force is identical 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, this specific SKU lacks the -S option and does not have a piston magnet, so it cannot accept reed or electronic switches. You must use external mechanical dogs or limit sensors for position detection.
