Airtac SDAD Double Rod Slim Cylinder SDAD100X40S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X40S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 40mm 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 SDAD100X40S
The AirTAC SDAD100X40S is a double-acting, double-rod compact cylinder featuring a 100mm bore and 40mm stroke. Because the 32mm piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 3524.9 N at 0.5 MPa in each direction.
The through-rod design inherently resists twisting, allowing you to mount a work tool on one end and a position dog on the opposite side simultaneously. Equipped with a built-in magnet (-S), it supports AirTAC reed or electronic switches. The short body saves axial mounting depth, while end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD100X40S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X40S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 40 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 SDAD100X40S Is Used
Heavy-Duty Stamping
Drives a symmetric stamping die where the equal 3524.9 N push and pull force prevents tool binding during high-tonnage forming operations.
Balanced Vertical Lift
Lifts heavy platens vertically; the dual-end through-rod resists twisting under offset loads while maintaining stable 179.7 kg vertical lift capacity.
Dual-End Transfer
Mounts a gripper on one rod end and a magnetic dog on the opposite end to trigger an electronic switch, saving axial space in compact transfer lines.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X40S the Right Cylinder?
When sizing this model, compare its 3524.9 N @0.5 MPa capacity with the adjacent SDAD80, which provides 2267.8 N @0.5 MPa. Stepping up to the 100mm bore gives a significant boost for heavy loads, yielding a safe working load around 2115 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity of roughly 179.7 kg with a 2:1 margin. The PT3/8 air port feeds the chamber, and the female M18x1.5 rod-end threads accommodate robust tooling.
Remember that a plain double-rod cylinder drifts when air is lost or the valve centers; the fixed NBR bumper only decelerates near stroke end and acts as neither a lock nor a brake. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration includes the -S magnet for sensing and operates at 30-500 mm/s.
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 SDAD100X40S 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 exiting both ends resists rotation and allows mounting a tool on one end and a sensor dog on the other. It also ensures push and pull forces remain identical, which is ideal for symmetric loads.
