Airtac SDAD Double Rod Slim Cylinder SDAD40X110
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X110 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 SDAD40X110
The AirTAC SDAD40X110 is a double-acting, double-rod compact cylinder featuring a 40 mm bore and 110 mm stroke. Because a 16 mm rod exits both ends of the riveted body, the annular piston area is identical in each direction, yielding exactly 527.8 N of push and pull force at 0.5 MPa. This symmetric thrust is ideal for balancing loads that move back and forth without shifting the center of mass.
The through-rod geometry inherently resists twisting, allowing you to mount a work tool on one end and a dog or fixture on the opposite end simultaneously. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Please note this specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD40X110 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X110 |
|---|---|
| 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 SDAD40X110 Is Used
Gripper Synchronization
Drives opposing gripper jaws via the dual-end rods, ensuring perfectly parallel clamping motion that resists twist during high-speed pick-and-place.
Symmetric Transfer Arm
Moves a transfer pallet 110 mm forward and back with matched 527.8 N force, preventing sag or uneven acceleration on the return stroke.
Balanced Lift Station
Lifts a 26.9 kg vertical load using both rod ends to maintain platform levelness, avoiding the rotational play common to single-rod designs.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X110 the Right Cylinder?
When sizing this unit, compare its symmetric 527.8 N thrust at 0.5 MPa against adjacent bores: the SDAD32 provides 345.6 N, while the SDAD50 offers 824.7 N. The 110 mm stroke falls within the 130 mm standard maximum for this bore.
The dual-end through-rod prevents rotation and enables dual-end tooling, but a plain cylinder drifts when air is lost or the valve centers—the fixed bumper only decelerates impact near stroke end and acts as neither a lock nor a brake. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration uses a PT1/8 port, female M8x1.25 rod threads, 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 SDAD40X110 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. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod resists twisting and allows tooling on one end while using the opposite end for a dog or mechanical fixture. However, this specific SKU has no piston magnet, so it cannot accept magnetic reed or electronic switches without changing to the -S variant.
