Airtac SDAD Double Rod Slim Cylinder SDAD63X55SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X55SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 55mm 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 SDAD63X55SB
The AirTAC SDAD63X55SB is a compact double-acting 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, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric thrust is a major advantage for loads requiring consistent kinetic energy on extend and retract strokes.
This specific configuration includes a built-in piston magnet for position sensing and male M18x1.5 rod threads on both ends. The 63 mm bore uses a PT1/4 air port and operates at speeds between 30 and 500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, which keeps the overall axial footprint short for tight machinery layouts.
Airtac SDAD Double Rod Slim Cylinder SDAD63X55SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X55SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 55 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 SDAD63X55SB Is Used
Symmetrical Transfer Chuck
Grips and shifts components with identical 1401.5 N clamping force on both the extend and retract strokes, preventing part deformation during bidirectional transfers.
Dual-End Lifting Jig
Uses the male M18x1.5 rods on both ends to drive a lift carriage on one side while mounting a magnetic dog on the other for precise height confirmation.
Anti-Rotation Guide Pusher
The fixed through-rod resists twisting forces during heavy horizontal pushing tasks, maintaining alignment without needing external guide rods.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X55SB the Right Cylinder?
When sizing this unit, consider the neighboring bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the larger SDAD80 offers 2267.8 N. The 63 mm bore provides a safe working load of roughly 841 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity near 71.4 kg with a 2:1 safety margin. The through-rod geometry resists twisting and allows you to mount a tool on one end while tracking position with a reed or electronic switch on the opposite end.
This model features a 55 mm stroke (within the 130 mm standard limit) and male M18x1.5 threads. Remember that a plain double-rod cylinder does not hold position if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, you must integrate an external rod lock or a 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 SDAD63X55SB FAQ
The force is equal in both directions due to the double-rod design. It delivers 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 maximum operating pressure is 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke near the end caps; it does not act as a brake. You need an external rod lock or pilot-operated check valve for load holding.
