Airtac SDAD Double Rod Slim Cylinder SDAD50X110B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X110B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 110mm 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 SDAD50X110B
The AirTAC SDAD50X110B is a compact double-acting 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, giving you 824.7 N of push and pull force at 0.5 MPa. This symmetry prevents twisting and allows you to mount a work tool on one end while using the opposite side for a secondary action.
This specific SKU uses male M18x1.5 threads on both 20 mm rods and a PT1/4 port. The 110 mm stroke stays within the 130 mm standard limit. End-stop energy is managed solely by a fixed NBR bumper, so for high-speed cycles you should slow the approach or add external shock absorbers.
Airtac SDAD Double Rod Slim Cylinder SDAD50X110B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X110B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 110 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 SDAD50X110B Is Used
Symmetric Pinching
Drives a dual-jaw gripper where the equal 824.7 N extend and retract forces keep clamping pressure perfectly balanced across the 110 mm travel.
Dual-End Transfer
Mounts a male M18x1.5 tool on one rod end and a dog on the opposite end to trip a mechanical limit while shifting parts on a 50 mm bore line.
Lift and Lower
Raises a 42 kg vertical payload using the 20 mm through-rod, relying on the fixed NBR bumper to soften the stops at both the top and bottom of the stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X110B the Right Cylinder?
When sizing this unit, stepping down to the SDAD40 yields 527.8 N at 0.5 MPa, while stepping up to the SDAD63 provides 1401.5 N. This 50 mm bore offers a safe working load of roughly 495 N (about 60 percent of the 0.5 MPa figure) and can vertically lift around 42 kg with a 2:1 safety margin.
The through-rod geometry provides excellent anti-rotation stability for dual-end mounting. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed NBR bumper only decelerates near the stroke end and acts as neither a lock nor a brake. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration lacks the -S magnet, so it cannot accept reed or electronic switches.
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 SDAD50X110B FAQ
The push and pull forces are identical because of the double-rod design. 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.
Yes, the through-rod exits both sides with male M18x1.5 threads, allowing you to drive a tool on one end and a dog on the other. The dual-rod geometry also resists twisting. This SKU lacks a piston magnet, so it cannot be used with magnetic switches.
