Airtac SDAD Double Rod Slim Cylinder SDAD40X130
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X130 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 130mm 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 SDAD40X130
The AirTAC SDAD40X130 is a double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, delivering an equal push and pull force of 527.8 N at 0.5 MPa. This symmetry is essential when driving loads that require consistent momentum control in both travel directions.
This specific configuration utilizes a 16 mm piston rod and PT1/8 ports. The extended 130 mm stroke exceeds the standard maximum for this bore, making it a nonstandard stroke configuration. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, which absorbs shock effectively but requires external shock absorbers if cycling at the maximum 500 mm/s speed.
Airtac SDAD Double Rod Slim Cylinder SDAD40X130 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X130 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 130 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 SDAD40X130 Is Used
Long-Stroke Gripper Transfer
Moves parts across a 130 mm gap with equal 527.8 N force in both directions, ensuring the gripper decelerates smoothly without twisting on the return trip.
Dual-End Feeder Mechanism
Uses the through-rod to push a component on the front side while a mechanical dog trips an external limit switch on the rear, saving axial space.
Vertical Lift Stopper
Raises and lowers a 26.9 kg payload using the equal pull force, relying on the fixed NBR bumper to soften the impact at the top and bottom of the 130 mm travel.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X130 the Right Cylinder?
When sizing this unit, consider the neighboring bores: the SDAD32 provides 345.6 N at 0.5 MPa, while the SDAD50 offers 824.7 N. The through-rod geometry resists twisting forces, allowing you to mount a tool on one end and a dog on the opposite end simultaneously.
This SKU lacks the S suffix, meaning it has no piston magnet and cannot support reed or electronic switches. Rod-end threads are female M8x1.25 (or male M14x1.5 on B-coded variants). Remember that a standard cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, integrate an external rod lock or a 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 SDAD40X130 FAQ
The double-rod design provides equal force in both directions: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa. The 130 mm stroke is nonstandard for this 40 mm bore, which typically maxes out at 120 mm.
No, this specific model lacks the S option code, so it has no piston magnet and cannot trigger reed or electronic switches. You must use the S variant for magnetic sensing, though you can still mount external mechanical dogs on the exposed rod.
