Airtac SDAD Double Rod Slim Cylinder SDAD63X30B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X30B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 30mm 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 SDAD63X30B
The AirTAC SDAD63X30B is a double-acting, double-rod compact cylinder engineered for symmetric load handling. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This through-rod geometry inherently resists twisting, providing stable guidance for rigid tooling.
Featuring a 63 mm bore and 30 mm stroke, this unit saves axial mounting depth compared to standard round-body options. It features male M18x1.5 thread on both rod ends and uses a PT1/4 air port. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot support magnetic sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD63X30B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X30B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 30 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 SDAD63X30B Is Used
Symmetric Lifting Jig
Drives a rigid vertical lift where the equal 1401.5 N push/pull force prevents sagging on the return stroke.
Dual-End Transfer
Mounts a grip on one male M18x1.5 rod end and a cam dog on the opposite side to trigger external mechanical valves.
Anti-Rotation Guide
Handles a heavy pressing task where the 20 mm through-rod resists twisting under offset loads.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X30B the Right Cylinder?
When sizing this unit, consider the adjacent bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the SDAD80 offers 2267.8 N. The 63 mm bore provides a computed safe working load of roughly 841 N (about 60 percent of the 0.5 MPa rating), making it suitable for vertical lifts up to 71.4 kg with a 2:1 safety margin. The through-rod design allows you to mount a work tool on one end and a dog or mechanical stop on the opposite end simultaneously.
This configuration includes the B option, meaning both rod ends feature male M18x1.5 threads. Remember that a plain cylinder drifts when air is removed or the valve centers; the fixed bumper only decelerates near stroke end and does not lock the load. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Operating speed ranges from 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 SDAD63X30B FAQ
The push and pull forces are identical because the rod occupies both chambers. It generates 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.
No, this specific SKU does not have a piston magnet. You would need the SDAD63X30BS variant, which includes a built-in magnet compatible with AirTAC reed or electronic switches mounted in the body grooves.
