Airtac SDAD Double Rod Slim Cylinder SDAD50X35S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X35S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm 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 SDAD50X35S
The AirTAC SDAD50X35S is a double-acting compact cylinder featuring a 50mm bore and a 35mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 824.7 N at 0.5 MPa in either direction. The short body design drastically reduces axial mounting depth compared to traditional round-body options.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for position sensing. The 20mm through-rod naturally resists twisting, allowing you to drive a tool on one end while mounting a dog or sensor on the opposite side. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston near the end caps rather than acting as an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X35S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X35S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 35 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 SDAD50X35S Is Used
Symmetric Transfer Chuck
Ideal for gripping and moving parts where the 824.7 N equal push and pull force prevents part distortion during bidirectional clamping.
Anti-Rotation Guide Arm
The 20mm through-rod resists twisting, keeping a measuring or inspection probe perfectly aligned on the opposite end from the drive tool.
Vertical Lift Stopper
Handles a 42 kg vertical lift with a 2:1 margin, using the dual-end geometry to mount a dog on the rear rod for end-of-travel signaling.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X35S the Right Cylinder?
When sizing this model, compare its symmetric output with neighboring bores. Stepping down to the SDAD40 yields 527.8 N at 0.5 MPa, while stepping up to the SDAD63 provides 1401.5 N at 0.5 MPa. The 50mm bore strikes a middle ground, offering a safe working load of roughly 495 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of approximately 42 kg with a 2:1 safety margin. The PT1/4 port and 20mm rod diameter are fixed by the bore.
This configuration includes the -S magnet for switch readiness and female M10x1.5 rod-end threads on both ends. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed NBR bumper only decelerates the stroke end and does not lock the load. For vertical load holding without live pressure, install 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 SDAD50X35S FAQ
The double-rod design provides 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.
Yes, the through-rod exits both ends, allowing you to mount a tool on one side and a dog or switch on the other. The included -S magnet works with AirTAC reed or electronic switches.
