Airtac SDAD Double Rod Slim Cylinder SDAD40X35SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X35SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 35mm 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 SDAD40X35SB
The AirTAC SDAD40X35SB is a compact double-acting cylinder featuring a piston rod exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area is identical on extension and retraction, yielding exactly 527.8 N of force at 0.5 MPa in both directions. This symmetric output is ideal for balanced tooling.
This 40 mm bore unit uses a 16 mm rod and a PT1/8 port. Equipped with a built-in magnet (-S), it supports AirTAC reed or electronic switches for position sensing. The -B option specifies male M14x1.5 rod threads at both ends. End-of-stroke deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD40X35SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X35SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 35 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 SDAD40X35SB Is Used
Symmetric Transfer Jaws
Drives opposing gripper jaws with identical 527.8 N force on both strokes, ensuring parts remain centered during horizontal transfers.
Anti-Rotation Guide Post
Uses the twin 16 mm rods exiting both ends to resist twisting torque on a precision alignment fixture, maintaining parallelism.
Dual-End Lift Station
Mounts a lift fork on one male M14x1.5 rod end and a position dog on the opposite end to trigger a reed switch at mid-stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X35SB the Right Cylinder?
When sizing this unit, compare its bidirectional 527.8 N output at 0.5 MPa against adjacent bores. Dropping to an SDAD32 yields 345.6 N, while stepping up to an SDAD50 provides 824.7 N. The through-rod geometry prevents twisting and permits mounting a tool on one end with a dog on the opposite end.
Remember that a standard cylinder drifts when air is removed or a valve centers, as the fixed bumper only decelerates 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 includes the magnet for sensing and male M14x1.5 threads on both 16 mm rods.
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 SDAD40X35SB FAQ
The push and pull forces are equal because the rod occupies both chambers. It generates 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.
The through-rod provides equal force in both directions and resists twisting. It allows you to drive a tool on one end while mounting a dog or switch on the opposite end. The -S magnet enables sensing with AirTAC reed or electronic switches.
