Airtac SDAD Double Rod Slim Cylinder SDAD63X75SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X75SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 75mm 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 SDAD63X75SB
The AirTAC SDAD63X75SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies both chambers, the annular area is identical in each direction, giving you exactly 1401.5 N of push and pull force at 0.5 MPa. This symmetric thrust is ideal for balancing loads that require consistent resistance regardless of travel direction.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, along with male M18x1.5 threads on both 20 mm rod ends. The short body design drastically reduces required 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 SDAD63X75SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X75SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 75 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 SDAD63X75SB Is Used
Symmetric Clamping Press
Uses the equal 1401.5 N bidirectional force to clamp components securely from both sides without shifting the load center.
Dual-End Lift Station
Mounts a lifting jaw on one male M18x1.5 rod end and a position dog on the other to trigger a reed switch mid-stroke.
Anti-Rotation Guide Arm
Exploits the twin 20 mm through-rod to resist twisting torque during precision feeding tasks within a tight 75 mm stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X75SB the Right Cylinder?
When sizing this unit, compare its 1401.5 N @0.5 MPa capacity against adjacent bores: the SDAD50 provides 824.7 N, while the SDAD80 offers 2267.8 N. For this 63 mm bore, a safe working load is approximately 841 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 71.4 kg with a 2:1 safety margin. The through-rod geometry prevents twisting and allows you to mount a tool on one end while tracking position with a switch on the opposite side.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve centers, as the NBR bumper only decelerates near the stroke end and acts as no lock. For load-holding requirements without live pressure, install an external rod lock or a pilot-operated check valve. This model features a 75 mm stroke, a PT1/4 port, the -S magnet, and male M18x1.5 rod threads.
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 SDAD63X75SB FAQ
The push and pull forces are equal because the rod exits both ends. 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. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod design allows driving a tool on one end while mounting a dog or switch on the opposite end. This unit has male M18x1.5 threads on both rod ends and includes the -S magnet for use with AirTAC reed or electronic switches.
