Airtac SDAD Double Rod Slim Cylinder SDAD100X70SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X70SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 70mm 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 SDAD100X70SB
The AirTAC SDAD100X70SB is a double-acting, double-rod compact cylinder engineered for high-load symmetry. Because the 32 mm through-rod occupies both chambers, the annular area is identical on extend and retract, yielding an equal push and pull force of 3524.9 N at 0.5 MPa. This geometric balance prevents twisting and ensures stable motion for heavy tooling.
Despite its 100 mm bore, the riveted body saves axial mounting depth compared to standard profile designs. This specific configuration includes a built-in magnet for reed or electronic switches and features male M26x1.5 rod threads on both ends. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion or a locking brake.
Airtac SDAD Double Rod Slim Cylinder SDAD100X70SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X70SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 70 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M18×1.5 female / M26×1.5 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3525 N |
| 0.7 MPa | 4935 N |
| Max (@1.0 MPa) | 719 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 SDAD100X70SB Is Used
Heavy-Duty Press Fitment
Utilizes the 3524.9 N equal extend and retract force to seat heavy industrial components without rotational drift during the pressing cycle.
Symmetric Lift Station
Lifts payloads up to 179.7 kg vertically with a 2:1 margin, relying on the dual-end 32 mm rod to maintain parallel stability and resist twisting.
Dual-End Transfer Mechanism
Mounts a primary gripper on one male M26x1.5 rod end and a position dog on the opposite end, allowing a reed or electronic switch to track motion without interference.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X70SB the Right Cylinder?
Selecting this 100 mm bore model provides massive symmetric force. Sizing both ways: stepping down to SDAD80 offers 2267.8 N at 0.5 MPa, whereas this SDAD100X70SB delivers 3524.9 N. A computed safe working load is roughly 2115 N, allowing a vertical lift of approximately 179.7 kg with a 2:1 safety margin. The through-rod design allows you to mount a tool on one end and a dog on the opposite end simultaneously.
This unit features a PT3/8 port and male M26x1.5 rod threads at both ends. Remember that a plain cylinder does not hold its load when air is lost or the valve is centered; the piston drifts. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. The fixed NBR bumper only decelerates near the stroke end.
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 SDAD100X70SB FAQ
The force is equal in both directions due to the double-rod design. It generates 3524.9 N at 0.5 MPa, 4934.8 N at 0.7 MPa, and a theoretical maximum of 719 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
The through-rod resists twisting under heavy loads and provides identical extend and retract forces. It also allows you to drive tooling on one end while mounting a position dog on the opposite end for a reed or electronic switch.
