Airtac SDAD Double Rod Slim Cylinder SDAD100X85B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X85B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 85mm 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 SDAD100X85B
The AirTAC SDAD100X85B is a double-acting, double-rod compact cylinder engineered for heavy-duty symmetry. Because a 32 mm rod exits both ends of the riveted body, the annular piston area is identical in each chamber, yielding exactly 3524.9 N of push and pull force at 0.5 MPa. This equal-force geometry eliminates thrust reversal, ensuring stable performance in demanding press or lift operations.
Featuring male M26x1.5 threads on both rod ends, this 100 mm bore unit supplies a theoretical maximum output of 719 kgf at 1.0 MPa. The short body design minimizes axial footprint compared to conventional round-body cylinders, while the fixed NBR bumpers absorb end-of-stroke shock. Operating at speeds of 30-500 mm/s, it uses a PT3/8 port to drive high-volume airflow efficiently.
Airtac SDAD Double Rod Slim Cylinder SDAD100X85B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X85B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 85 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 SDAD100X85B Is Used
Heavy-Duty Stamping Press
Applies 4934.8 N of identical force extending and retracting to form thick metal sheets without reversing thrust loads.
Symmetric Vertical Lift
Raises and lowers 179.7 kg platforms smoothly, relying on the dual-end 32 mm rods to prevent platform twisting during transit.
Dual-End Transfer Mechanism
Drives a primary gripper on one male M26x1.5 rod end while mounting a cam dog on the opposite end to trip external limit sensors.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X85B the Right Cylinder?
When sizing this model, consider the force step between neighboring bores. Dropping down to an SDAD80 provides 2267.8 N at 0.5 MPa, which may be insufficient for high-mass tooling, whereas the SDAD100X85B provides a safe working load of roughly 2115 N (about 60% of its 0.5 MPa rating). This makes it ideal for vertically lifting loads up to 179.7 kg with a 2:1 safety margin. The through-rod design inherently resists mechanical twisting, allowing you to mount a primary tool on one end and a dog or secondary mechanism on the opposite male M26x1.5 threaded end.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve centers; the NBR bumper only decelerates the stroke end and acts as neither a lock nor a brake. To hold a suspended load securely, integrate an external rod lock or a pilot-operated check valve. This specific SKU lacks a piston magnet, so position sensing is unavailable unless you upgrade to the -S variant for AirTAC reed or electronic switches.
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 SDAD100X85B FAQ
The double-rod design provides equal force in both directions: 3524.9 N at 0.5 MPa and 4934.8 N at 0.7 MPa. The theoretical maximum output is 719 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept AirTAC reed or electronic switches. You would need the -S variant for internal magnetic sensing, though you can still mount external physical dogs to the male M26x1.5 rods.
