Airtac SDAD Double Rod Slim Cylinder SDAD50X75B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X75B 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 SDAD50X75B
The AirTAC SDAD50X75B is a double-acting compact cylinder featuring a 50 mm bore and a 75 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber. This geometry ensures push and pull forces match exactly at 824.7 N for 0.5 MPa, providing stable symmetric motion. The short body design drastically reduces axial mounting depth compared to conventional round-body units.
This specific SKU includes male M18x1.5 threaded rods on both ends for direct tool mounting. A fixed NBR bumper decelerates the piston near stroke limits within the 30-500 mm/s speed range. Note this version lacks a piston magnet, so position sensing is not supported without the -S option.
Airtac SDAD Double Rod Slim Cylinder SDAD50X75B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X75B |
|---|---|
| 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 SDAD50X75B Is Used
Gripper Jaw Actuation
Drives opposing gripper fingers with identical 824.7 N force in both directions, ensuring parts are clamped securely without rotational deflection during transfer.
Symmetric Lift Stations
Elevates platform assemblies using the male M18x1.5 threads on both ends, maintaining balanced vertical lifting of roughly 42 kg without twisting under load.
Dual-End Transfer Pushers
Pushes workpieces from one conveyor lane to another while simultaneously engaging a mechanical dog on the opposing rod end to trigger downstream sequencing.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X75B the Right Cylinder?
When sizing this unit, consider the neighbouring bores. Stepping down, the SDAD40 yields 527.8 N at 0.5 MPa, while moving up to the SDAD63 provides 1401.5 N at 0.5 MPa. This 50 mm model offers a computed safe working load of roughly 495 N, translating to a vertical lift capacity of about 42 kg with a 2:1 safety margin. The through-rod design inherently resists twisting, allowing you to drive a tool on one end while leaving the opposite end free for a dog or secondary mechanism.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve centers. The fixed NBR bumper only absorbs end-of-stroke shock and acts as neither an adjustable air cushion nor a locking brake. For load-holding requirements, integrate an external rod lock or a pilot-operated check valve. This configuration features a PT1/4 port, no magnet, and male M18x1.5 rod threads.
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 SDAD50X75B 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. Operating pressure ranges from 0.15 to 1.0 MPa.
Yes, the through-rod extends from both sides, allowing you to attach a tool via the male M18x1.5 threads on one end and a dog or fixture on the other. This geometry also prevents the piston from twisting during operation.
