Airtac SDAD Double Rod Slim Cylinder SDAD63X25B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X25B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 25mm 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 SDAD63X25B
The AirTAC SDAD63X25B 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, yielding exactly 1401.5 N of force at 0.5 MPa on both extend and retract strokes. This symmetry is vital for applications requiring perfectly balanced push and pull dynamics.
Equipped with male M18x1.5 rod threads on both ends, this 63 mm bore unit saves axial mounting depth compared to standard profile bodies. It operates at 30-500 mm/s and relies on a fixed NBR bumper at each end to absorb end-of-stroke shock. Note that this specific SKU lacks a piston magnet, so it cannot directly host magnetic switches without modifying the build.
Airtac SDAD Double Rod Slim Cylinder SDAD63X25B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X25B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 25 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 SDAD63X25B Is Used
Gripper Synchronization
Drives opposing gripper jaws using the dual male M18x1.5 rod ends, ensuring perfectly parallel clamping motion that resists rotational twist under high loads.
Balanced Lift Stations
Lifts 71.4 kg vertical payloads safely, leveraging the identical 1401.5 N extend and retract forces to prevent sagging or asymmetric acceleration on ascent and descent.
Dual-End Transfer
Mounts a pusher plate on one rod end and a mechanical dog on the opposite end, allowing external physical signaling without sacrificing the 25 mm compact stroke depth.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X25B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD50 provides 824.7 N at 0.5 MPa, while moving up to the SDAD80 yields 2267.8 N. The 63 mm bore offers a computed safe working load of roughly 841 N (about 60% of the 0.5 MPa figure), which translates to a vertical lift capacity of approximately 71.4 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting and allows you to drive a tool on one end while leaving the opposite end free for mechanical synchronization. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the fixed NBR bumper only decelerates the stroke end and does not function as a lock. For secure load holding, integrate an external rod lock or pilot-operated check valve. This model features a PT1/4 port, a 25 mm stroke, male M18x1.5 rod threads, and no 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 SDAD63X25B FAQ
Because the rod exits both ends, push and pull forces are perfectly equal. It generates 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 in both directions.
No, this specific SKU does not include a piston magnet. You would need the -S variant to utilize AirTAC reed or electronic switches in the body sensor grooves. The dual male M18x1.5 rod ends still provide excellent anti-rotation support for external mechanical tracking.
