Airtac SDAD Double Rod Slim Cylinder SDAD100X120B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X120B 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 SDAD100X120B
The AirTAC SDAD100X120B is a double-acting compact cylinder featuring a 100mm bore and 120mm stroke. Because the piston rod exits both ends, the annular area remains identical in extend and retract motions, yielding an equal push and pull force of 3524.9 N at 0.5 MPa. This symmetric thrust is ideal for driving heavy loads without inducing directional bias.
Equipped with male M26x1.5 threads on both 32mm rod ends, this unit allows dual-end tool mounting while the through-rod geometry inherently resists mechanical twisting. The short riveted body minimizes axial footprint compared to standard round-body options. End-of-stroke deceleration relies on a fixed NBR bumper, not an adjustable air cushion. Note this SKU lacks a piston magnet, so position sensing is not supported without the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD100X120B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X120B |
|---|---|
| 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 SDAD100X120B Is Used
Heavy-Duty Lift Stations
Drives vertical lifting platforms requiring equal force both up and down, safely handling loads around 179.7 kg with a 2:1 margin.
Twin-Tool Machining
Mounts a cutting tool on one male M26x1.5 rod end and a dog on the opposite end, utilizing the anti-rotation through-rod for strict alignment.
Riveting Presses
Provides 4934.8 N of force at 0.7 MPa for symmetric pressing operations where the compact riveted body limits overall machine depth.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X120B the Right Cylinder?
When sizing this 100mm bore actuator, compare its 3524.9 N output at 0.5 MPa against the smaller SDAD80, which provides 2267.8 N. If your application requires less force, stepping down saves space, but if you need maximum symmetric thrust, this model safely handles a working load of roughly 2115 N, or a vertical lift of about 179.7 kg with a 2:1 safety margin. The through-rod design prevents rotation, enabling precise dual-end tooling or dog mounting.
This configuration features a 120mm stroke, PT3/8 air ports, and male M26x1.5 rod threads on both sides. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve centers, as the fixed NBR bumper only decelerates the stroke end rather than locking the load. For 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 SDAD100X120B FAQ
The push and pull forces are identical because the rod occupies both chambers. It generates 3524.9 N at 0.5 MPa and 4934.8 N at 0.7 MPa, with 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 because the fixed NBR bumper only decelerates the stroke end and does not act as a brake. Use an external rod lock for load holding. Additionally, this specific SKU lacks a piston magnet, so it cannot take reed or electronic switches without upgrading to the -S variant.
