Airtac SDAD Double Rod Slim Cylinder SDAD63X35SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X35SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 35mm 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 SDAD63X35SB
The AirTAC SDAD63X35SB is a compact double-acting cylinder featuring a piston rod exiting both ends of its riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, delivering an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric thrust is a major advantage when driving loads that require consistent kinetic energy on extension and retraction.
The through-rod geometry inherently resists twisting, providing stable guidance without external rails. Equipped with a built-in magnet, this unit supports reed or electronic switches mounted directly into the body sensor grooves. It features male M18x1.5 thread on both rod ends and a PT1/4 port. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD63X35SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X35SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 35 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 SDAD63X35SB Is Used
Symmetric Transfer Arms
Drives pick-and-place arms where the 1401.5 N equal force ensures stable acceleration and deceleration of heavy payloads in both travel directions.
Dual-End Lift Stations
Uses the through-rod to lift a platform on one end while mounting an electronic switch dog on the opposite side to confirm elevation.
Anti-Rotation Guiding
Resists twisting moments during precision pressing tasks, maintaining tool alignment without requiring bulky external linear bearings.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X35SB the Right Cylinder?
When sizing this unit, compare its 1401.5 N output at 0.5 MPa against adjacent bores: the SDAD50 provides 824.7 N, while the larger SDAD80 yields 2267.8 N. For this 63 mm bore, a safe working load is approximately 841 N, allowing a vertical lift of roughly 71.4 kg with a 2:1 safety margin. The dual-end male M18x1.5 rods let you mount a tool on one side and a position dog on the opposite end simultaneously.
Remember that a standard cylinder does not hold position if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. This specific configuration includes the S magnet for sensing and the B male rod thread, operating at speeds of 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 SDAD63X35SB FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 1401.5 N at 0.5 MPa, 1962.2 N at 0.7 MPa, and a theoretical maximum of 286 kgf at 1.0 MPa.
The through-rod resists twisting and allows you to mount a tool on one end and a reed or electronic switch dog on the other. It also ensures push force equals pull force for symmetric load handling.
