Airtac SDAD Double Rod Slim Cylinder SDAD63X90S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X90S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 90mm 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 SDAD63X90S
The AirTAC SDAD63X90S 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, giving you exactly 1401.5 N of thrust and pull force at 0.5 MPa. This symmetric output is ideal for balancing loads without tweaking pressure regulators.
A 90 mm stroke moves the 20 mm diameter piston rod at speeds between 30 and 500 mm/s. The short body design saves axial mounting depth compared to standard round-body options. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, and the built-in magnet (-S) supports reed or electronic switches for position tracking.
Airtac SDAD Double Rod Slim Cylinder SDAD63X90S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X90S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 90 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 SDAD63X90S Is Used
Symmetric Lift Stations
Drives vertical lifting platforms where matching 1401.5 N extend and retract forces prevent sagging during upward and downward transit cycles.
Dual-End Transfer Arms
Mounts a gripper on the front rod and a magnetic dog on the rear to trigger a reed switch, using the anti-rotation through-rod for stable part handoffs.
Guided Pressing Fixtures
Executes 90 mm pressing strokes on light assemblies, relying on the twin rods to resist twisting under offset loads without extra guide shafts.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X90S the Right Cylinder?
When sizing this 63 mm bore unit, compare its 1401.5 N @0.5 MPa output against neighboring bores: the SDAD50 yields 824.7 N, while the SDAD80 provides 2267.8 N. The equal push-pull geometry and through-rod prevent twisting during transit, allowing you to mount a work tool on one end and a position dog on the opposite side. This configuration yields a safe working load of roughly 841 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity near 71.4 kg with a 2:1 safety margin.
This model includes a PT1/4 port, female M10x1.5 rod-end threads on both sides, and the -S magnet for sensing. Remember that a standard cylinder drifts when air is removed or the valve centers; the NBR bumper only decelerates near the stroke end and will not hold the load. For secure vertical positioning without live pressure, install an external rod lock or pilot-operated check valve.
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 SDAD63X90S 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 to resist rotation and allows you to drive a tool on one end while mounting a dog on the other. The built-in -S magnet works with AirTAC reed or electronic switches in the body grooves to track position.
