Airtac SDAD Double Rod Slim Cylinder SDAD40X110SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X110SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 110mm 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 SDAD40X110SB
The AirTAC SDAD40X110SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber equally, the annular area remains constant, delivering identical push and pull forces of 527.8 N at 0.5 MPa. This symmetric thrust is ideal for balancing loads without tweaking pressure regulators.
This specific configuration includes a built-in magnet for position sensing and male M14x1.5 rod threads on both ends. The 16 mm diameter rods resist twisting during extension, while the short body profile saves valuable axial mounting depth. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD40X110SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X110SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 110 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SDAD40X110SB Is Used
Gripper Synchronization
Drives opposing gripper jaws where the 527.8 N equal bidirectional force ensures perfectly balanced clamping pressure on delicate extrusions.
Elevator Counterbalance
Lifts a 26.9 kg vertical platform using the anti-rotation through-rod to prevent carriage twisting during the 110 mm travel.
Dual-End Transfer
Mounts a male M14x1.5 tooling head on one end and a magnetic dog on the other to trigger a reed switch mid-stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X110SB the Right Cylinder?
When sizing this unit, compare its 527.8 N output at 0.5 MPa against adjacent bores. Dropping down to the SDAD32 provides 345.6 N, whereas stepping up to the SDAD50 yields 824.7 N.
The through-rod geometry prevents rotation and permits mounting a tool on one end while tracking position with a reed or electronic switch on the opposite side. Remember that the fixed bumper only decelerates the stroke end; a plain cylinder drifts if air pressure drops, so add an external rod lock or pilot-operated check valve for load holding. This model features a 110 mm stroke, PT1/8 port, the -S magnet, and male M14x1.5 threads.
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 SDAD40X110SB FAQ
The double-rod design provides equal force in both directions: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. The theoretical maximum is 108 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke near the end; for load holding without live pressure, you must install an external rod lock or pilot-operated check valve.
