Airtac SDAD Double Rod Slim Cylinder SDAD63X50SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X50SB 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 SDAD63X50SB
The AirTAC SDAD63X50SB is a double-acting compact cylinder featuring a 63mm bore and 50mm stroke, with piston rods exiting both ends of its riveted body. Because the rod occupies each chamber equally, the annular area is symmetric, yielding an identical push and pull force of 1401.5 N at 0.5 MPa. This symmetric output is ideal for driving loads that require stable, balanced motion without twisting.
This specific configuration includes a built-in piston magnet (-S) for position sensing and male M18x1.5 threads (-B) on both 20mm rod ends. The short body design drastically reduces required axial mounting depth compared to standard round-body options. 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 SDAD63X50SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X50SB |
|---|---|
| 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 SDAD63X50SB Is Used
Symmetric Transfer Arms
Drives a pick-and-place arm from one end while the opposite rod end mounts a dog for switch activation, ensuring 1401.5 N of equal force in both extend and retract motions.
Balanced Lift Stations
Lifts vertically oriented platens without rotational drift, safely handling loads around 71.4 kg with a 2:1 safety margin at 0.5 MPa.
Dual-End Sealing Press
Compresses packaging materials using one rod end while the opposite side progresses through a secondary forming tool, capitalizing on the compact body to save machine depth.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X50SB the Right Cylinder?
When sizing this unit, consider the adjacent bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the larger SDAD80 offers 2267.8 N at 0.5 MPa. The 63mm bore sits perfectly for applications needing roughly 1401.5 N of symmetric force. A practical safe working load is about 841 N (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 design prevents rotation and lets you mount a tool on one end while tracking position with a reed or electronic switch on the opposite end. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; use an external rod lock or pilot-operated check valve for load holding. This model features a PT1/4 port, male M18x1.5 rod threads on both sides, and the -S magnet.
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 SDAD63X50SB FAQ
Because the double-rod design creates equal annular areas, the force is identical in both directions: 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.
Yes, the through-rod resists twisting and allows mounting tooling on both male M18x1.5 ends. The built-in magnet (-S) enables position tracking with an AirTAC reed or electronic switch along the body grooves.
