Airtac SDAD Double Rod Slim Cylinder SDAD40X60
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X60 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 60mm 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 SDAD40X60
The AirTAC SDAD40X60 is a double-acting compact cylinder featuring a 40mm bore and 60mm stroke, with twin piston rods exiting the riveted body. Because a rod occupies both internal chambers, the annular piston area is identical on extend and retract. This geometry yields equal push and pull force, delivering 527.8 N at 0.5 MPa in each direction, which is ideal for driving symmetric loads without reversal bias.
A 16mm rod diameter at both ends provides high torsional rigidity, resisting twist during traversal. The short body footprint saves axial mounting depth where larger profile cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper, and the PT1/8 port ensures adequate flow for the 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD40X60 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X60 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 60 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 SDAD40X60 Is Used
Parallel Gripper Jaw
Drives opposing gripper jaws with equal 527.8 N force in both directions, ensuring balanced clamping pressure on precision machined parts.
Dual-End Transfer Dog
Uses the anti-rotation through-rod to push a workpiece carrier on one end while simultaneously triggering a mechanical dog on the opposite side.
Vertical Lift Platform
Lifts a 26.9 kg vertical load with a 2:1 safety margin, leveraging the twin rods to prevent platform twisting during elevation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X60 the Right Cylinder?
When sizing this 40mm bore, compare its 527.8 N @0.5 MPa output both ways: dropping to SDAD32 provides 345.6 N, while stepping up to SDAD50 yields 824.7 N. This model has no piston magnet (no -S code), so it cannot host reed or electronic switches. Rod-end threads are female M8x1.25 on both ends. A safe working load is roughly 317 N, allowing a vertical lift of about 26.9 kg with a 2:1 safety margin.
The through-rod design prevents rotation and permits mounting a tool on one end and a dog on the opposite end. Remember that a plain cylinder drifts when air is lost or the valve is centered; the fixed NBR bumper only decelerates near stroke end and acts as neither a lock nor an adjustable air cushion. 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 SDAD40X60 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.
No, this specific SKU lacks the -S magnet option, so it cannot trigger AirTAC reed or electronic switches. You must use external proximity sensors or select an -S variant for internal magnetic sensing.
