Airtac SDAD Double Rod Slim Cylinder SDAD63X110B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X110B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm 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 SDAD63X110B
The AirTAC SDAD63X110B 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, meaning push force equals pull force at 1401.5 N under 0.5 MPa. This symmetric thrust is a major advantage for loads requiring perfectly balanced bidirectional driving.
This specific configuration features male M18x1.5 thread on both 20 mm rod ends, allowing direct mechanical fastening on opposing sides. The short body design saves axial mounting depth compared to traditional round-body units. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD63X110B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X110B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 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 (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 SDAD63X110B Is Used
Web Guiding Mechanism
Uses the dual male M18x1.5 rod ends to tension and steer material equally in both directions, relying on the 1401.5 N symmetric thrust to prevent tracking drift.
Balanced Lift Station
Raises and lowers a 71.4 kg platen vertically. The through-rod resists twisting during the 110 mm travel, maintaining precise vertical alignment without side play.
Reciprocating Transfer
Shuttles components between two processing stations. Equal force on extend and retract ensures consistent acceleration profiles across the 110 mm stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X110B the Right Cylinder?
When sizing this actuator, the 63 mm bore yields 1401.5 N at 0.5 MPa. Stepping down, the SDAD50 provides 824.7 N, while stepping up to the SDAD80 offers 2267.8 N. For your calculations, a safe working load is roughly 841 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of approximately 71.4 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and lets you mount a tool on one end and a dog on the opposite side. Note that this SKU lacks the -S magnet, so magnetic switches cannot be used. Furthermore, a plain cylinder drifts when air is lost or the valve centers; use an external rod lock or pilot-operated check valve for load holding.
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 SDAD63X110B FAQ
Because the double-rod design provides equal annular area on both sides, the push and pull forces are identical: 1401.5 N at 0.5 MPa, 1962.2 N at 0.7 MPa, and a maximum theoretical output of 286 kgf at 1.0 MPa.
Yes, the through-rod exits both ends with male M18x1.5 threads, allowing you to drive a tool on one side while mounting a dog or fixture on the other. The continuous rod also provides inherent anti-rotation resistance.
