Airtac SDAD Double Rod Slim Cylinder SDAD100X25SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X25SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm 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 SDAD100X25SB
The AirTAC SDAD100X25SB is a compact double-acting cylinder featuring a 100mm bore and a 25mm stroke, engineered with twin piston rods exiting both ends of its riveted body. This geometry creates identical annular areas on each side, ensuring push and pull forces remain exactly equal at 3524.9 N when operating at 0.5 MPa. The through-rod design inherently resists twisting, providing stable linear motion for heavy symmetric loads.
Equipped with a built-in magnet for reed or electronic switches and male M26x1.5 rod threads on both ends, this model maximizes utility in tight spaces. The short body depth saves valuable axial mounting length, while fixed NBR bumpers absorb end-of-stroke shock. Operating between 0.15 and 1.0 MPa, it achieves a maximum theoretical force of 719 kgf.
Airtac SDAD Double Rod Slim Cylinder SDAD100X25SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X25SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 25 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 SDAD100X25SB Is Used
Heavy-Duty Stamping
Delivers 4934.8 N at 0.7 MPa for symmetric pressing operations, utilizing the anti-rotation through-rod to keep the stamp head perfectly aligned.
Vertical Lift Stations
Raises 179.7 kg platforms with a 2:1 safety margin, relying on equal push and pull forces to smoothly lower the load without drift imbalance.
Dual-End Transfer
Mounts a gripper on one male M26x1.5 rod end and a position dog on the opposite end, leveraging the short riveted body to fit within compact transfer chutes.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X25SB the Right Cylinder?
When sizing this actuator, stepping down to the SDAD80 yields 2267.8 N at 0.5 MPa, whereas this 100mm bore provides 3524.9 N. Based on that 0.5 MPa rating, a safe working load is approximately 2115 N, which translates to a vertical lift capacity of roughly 179.7 kg with a 2:1 safety margin. This makes it ideal for substantial pressing or lifting duties where a smaller bore would stall.
The dual-end through-rod allows driving a tool on one side while mounting a dog or switch on the opposite end. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; utilize an external rod lock or pilot-operated check valve for strict load holding. This configuration includes the S magnet and B male M26x1.5 rod threads, with a PT3/8 port.
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 SDAD100X25SB FAQ
Because the double-rod design creates equal annular areas, force is identical in both directions: 3524.9 N at 0.5 MPa, 4934.8 N at 0.7 MPa, and a maximum theoretical 719 kgf at 1.0 MPa. The proof pressure is 1.5 MPa.
Yes, the through-rod exits both sides, allowing you to attach a tool to the male M26x1.5 thread on one end and a dog on the other. The built-in S magnet enables tracking via reed or electronic switches mounted in the body grooves.
