Airtac SDAD Double Rod Slim Cylinder SDAD63X50B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X50B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 50mm 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 SDAD63X50B
The AirTAC SDAD63X50B is a double-acting compact cylinder featuring a 63 mm bore and 50 mm stroke, with piston rods exiting both ends of the riveted body. Because a rod occupies each chamber, the annular area is identical in both directions, giving an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric output is ideal for balanced loads.
This specific SKU includes male M18x1.5 threads on both 20 mm rod ends, allowing direct mounting of tooling without extra adapters. The short body design minimizes axial footprint, while fixed NBR bumpers absorb end-of-stroke impact. Note this unit lacks a piston magnet and cannot support position sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD63X50B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X50B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 50 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SDAD63X50B Is Used
Web Guiding Mechanism
Utilizes the anti-rotation through-rod to maintain precise alignment of film or foil, preventing twist during high-speed shifts.
Symmetric Transfer Arm
Mounts a gripper on one male M18x1.5 end and a counterweight on the opposite end to balance the 1401.5 N force during part handoff.
Dual-End Lift Station
Drives a platform up and down with equal push and pull strength, ensuring stable vertical movement without sagging.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X50B the Right Cylinder?
When sizing this actuator, the SDAD50 provides 824.7 N at 0.5 MPa, whereas stepping up to the SDAD80 yields 2267.8 N at 0.5 MPa. The 63 mm bore offers a computed safe working load of roughly 841 N, or a vertical lift capacity of about 71.4 kg with a 2:1 safety margin. The through-rod geometry resists torsional twisting and permits driving a tool on one end while mounting a secondary mechanism on the opposite side.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve centers; the NBR bumper only decelerates the stroke end and does not function as a lock. For load-holding requirements, integrate an external rod lock or pilot-operated check valve. This configuration features a PT1/4 port, male M18x1.5 rod threads, and operates at 30-500 mm/s.
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 SDAD63X50B FAQ
The double-rod design provides equal force in both directions: 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The theoretical maximum is 286 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one male M18x1.5 end while attaching a secondary fixture to the other. This geometry also prevents the rod from twisting under load.
