Airtac SDAD Double Rod Slim Cylinder SDAD50X100B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X100B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 100mm 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 SDAD50X100B
The AirTAC SDAD50X100B is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, yielding equal push and pull forces of 824.7 N at 0.5 MPa. This symmetry is highly advantageous for driving loads that must move with consistent momentum in both directions.
This specific SKU includes male M18x1.5 threads on the 20 mm rods at both ends, allowing direct mounting of tooling on opposite sides. The short body design drastically reduces axial footprint compared to standard round-body options. End-of-stroke deceleration is handled by a fixed NBR bumper, and without a piston magnet, this base model does not support position sensing.

| 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SDAD50X100B Is Used
Caliper Gauge Actuation
Drives a measuring head on one end and a calibration dog on the opposite side, using the equal 824.7 N force to ensure symmetric pressure on both inward and outward strokes.
Dual-Side Transfer Pusher
Uses the male M18x1.5 threads on both ends to push a part from one conveyor to another, relying on the through-rod to prevent twist during the 100 mm traverse.
Vertical Lift Platform
Lifts a 42 kg payload with a 2:1 safety margin, taking advantage of the compact riveted body to save vertical space while maintaining identical force in both directions.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X100B the Right Cylinder?
When sizing this unit, consider the neighbouring bores: stepping down to the SDAD40 provides 527.8 N at 0.5 MPa, while stepping up to the SDAD63 yields 1401.5 N at 0.5 MPa. For this 50 mm bore, a safe working load is approximately 495 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 42 kg with a 2:1 safety margin. The 100 mm stroke falls within the 130 mm standard limit, and the unit features a PT1/4 port.
The through-rod geometry inherently resists twisting, making it superior for applications requiring anti-rotation stability or dual-end tooling. Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centred; the piston will drift. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. This configuration has male M18x1.5 rod threads and lacks the -S magnet option.
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 SDAD50X100B FAQ
The force is equal in both directions due to the double-rod design. It generates 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa, with a theoretical maximum of 168 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not have the -S option and therefore lacks a piston magnet, meaning it cannot accept reed or electronic switches. You would need the -S variant for position sensing. However, the male M18x1.5 threaded rods at both ends allow direct dual-end tooling mounting.
