Airtac SDAD Double Rod Slim Cylinder SDAD50X100SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X100SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 100mm 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 SDAD50X100SB
The AirTAC SDAD50X100SB 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 on extend and retract, yielding exactly 824.7 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balanced mechanisms.
The 50 mm bore uses a 20 mm piston rod and a PT1/4 port. Equipped with the -S magnet, it accepts reed or electronic switches in the body grooves. The -B option provides male M18x1.5 rod threads on both ends. End-of-stroke deceleration relies on a fixed NBR bumper, which is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X100SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X100SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 100 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SDAD50X100SB Is Used
Symmetric Transfer Chuck
Uses the equal 824.7 N extend and retract force to grip and release parts smoothly without directional force bias.
Dual-End Guiding Jig
Mounts a work tool on one male M18x1.5 rod end and a tracking dog on the opposite end for anti-rotation precision.
Vertical Lift Station
Lifts up to 42 kg with a 2:1 safety factor, relying on the through-rod to resist twisting during elevation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X100SB the Right Cylinder?
When sizing this 50 mm bore, the adjacent SDAD40 provides 527.8 N at 0.5 MPa, while the larger SDAD63 offers 1401.5 N. The 824.7 N output here gives a safe working load of roughly 495 N at a 60 percent margin, or a vertical lift capacity of about 42 kg with a 2:1 safety factor. The through-rod geometry prevents twisting and allows mounting a tool on one end and a position dog on the opposite side.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve centers, as the NBR bumper only decelerates near the stroke end. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. This configuration includes the S magnet and B male M18x1.5 rod threads, operating 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 SDAD50X100SB FAQ
The double-rod design produces equal force in both directions: 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa. The theoretical maximum is 168 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 centers. The fixed NBR bumper only decelerates the stroke end. For load holding, you must add an external rod lock or a pilot-operated check valve.
