Airtac SDAD Double Rod Slim Cylinder SDAD50X75SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X75SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 75mm 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 SDAD50X75SB
The AirTAC SDAD50X75SB 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 824.7 N at 0.5 MPa. This symmetry is highly advantageous when driving loads that require consistent momentum in both strokes.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, and male M18x1.5 rod threads on both ends. The short body design saves axial mounting depth where a larger cylinder will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X75SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X75SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 75 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 SDAD50X75SB Is Used
Gripper Jaw Sync
Drives opposing gripper jaws with equal 824.7 N force in both directions, maintaining parallel alignment without twisting during part transfer.
Dual-End Transfer
Mounts a pusher on the front rod and a position dog on the rear rod, utilizing the 75 mm stroke to index components smoothly on a packaging line.
Balanced Lift Station
Lifts approximately 42 kg of stacked material vertically, relying on the symmetric through-rod to prevent sagging and maintain a true vertical path.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X75SB the Right Cylinder?
When sizing this 50 mm bore, consider the SDAD40 at 527.8 N or the SDAD63 at 1401.5 N, both rated at 0.5 MPa, to ensure your application falls correctly between them. The through-rod geometry resists twisting and allows you to mount a tool on one end while tracking position with a switch on the opposite end. A safe working load is roughly 495 N, allowing a vertical lift of about 42 kg with a 2:1 margin.
This model features a 75 mm stroke, a PT1/4 port, and male M18x1.5 rod threads at both ends. Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. For load holding without live pressure, you must 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 SDAD50X75SB FAQ
The push and pull forces are equal because the rod exits both ends. It generates 824.7 N at 0.5 MPa, 1154.5 N at 0.7 MPa, and a theoretical maximum of 168 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
The through-rod resists rotation and allows you to mount tooling on one end while using the other end for a switch dog. The built-in magnet works with AirTAC reed or electronic switches to track position, and the male M18x1.5 threads secure fixtures on both ends.
