Airtac SDAD Double Rod Slim Cylinder SDAD50X5B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X5B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 5mm 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 SDAD50X5B
The AirTAC SDAD50X5B is a double-acting, double-rod compact cylinder featuring a 50 mm bore and a 5 mm stroke. Because the piston rod exits both ends, the annular area remains identical in each chamber, delivering an equal push and pull force of 824.7 N at 0.5 MPa. This symmetric output is ideal for balanced loads, while the through-rod geometry inherently resists twisting during operation.
This specific SKU includes male M18x1.5 thread on both rod ends and uses a PT1/4 air port. The short riveted body minimizes axial mounting depth where larger profile cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this variant lacks a piston magnet, so it cannot directly host magnetic switches without the -S option.
Airtac SDAD Double Rod Slim Cylinder SDAD50X5B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X5B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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 SDAD50X5B Is Used
Symmetric Ejector
Drives a part ejector where the equal 824.7 N push and pull force prevents binding on the return stroke.
Dual-End Transfer
Mounts a grip on one male M18x1.5 rod end and a position dog on the other to trigger an external sensor.
Compact Pin Insertion
Fits into tight multi-station fixtures using the short riveted body to press pins with matched bidirectional force.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X5B the Right Cylinder?
When sizing this unit, consider the 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 50 mm bore offers a safe working load of roughly 495 N, which translates to a vertical lift capacity of about 42 kg when applying a 2:1 safety margin. The through-rod design allows you to mount a tool on one end and a dog or switch on the opposite end simultaneously.
Keep in mind that a standard cylinder does not hold position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For load-holding requirements, integrate an external rod lock or a pilot-operated check valve. This configuration confirms a 50 mm bore, 5 mm stroke, PT1/4 port, male M18x1.5 rod threads, and no magnet.
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 SDAD50X5B 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.
No, this specific SKU does not have a piston magnet. You would need the -S variant to use AirTAC reed or electronic switches. However, the through-rod still allows mounting a physical dog on the opposite end to actuate external sensors.
