Airtac SDAD Double Rod Slim Cylinder SDAD100X50
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X50 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 50mm 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 SDAD100X50
The AirTAC SDAD100X50 is a double-acting, double-rod compact cylinder engineered for heavy-duty symmetric actuation. Because the 32 mm piston rod exits both ends of the riveted body, the annular area is identical in each chamber, yielding exactly 3524.9 N of force at 0.5 MPa on both the extend and retract strokes. This equal-force geometry eliminates thrust differential, providing stable motion for heavy payloads.
Designed to save axial mounting depth, the short body integrates a fixed NBR bumper at each end to decelerate the stroke. Operating at speeds of 30-500 mm/s via a PT3/8 port, it handles a safe working load of roughly 2115 N. The through-rod architecture inherently resists mechanical twisting, allowing you to drive a tool on one end while mounting a dog or fixture on the opposite side.
Airtac SDAD Double Rod Slim Cylinder SDAD100X50 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X50 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 50 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 SDAD100X50 Is Used
Heavy-Duty Lift Stations
Lifts 179.7 kg payloads vertically with a 2:1 safety margin, utilizing the equal 3524.9 N bidirectional force to prevent gravity-biased drift during retraction.
Twin-Spindle Machining
Drives a machining head on one end while the opposite rod end mounts a tracking dog, leveraging the 32 mm through-rod to resist torsional twisting under heavy cuts.
Large Mold Transfer
Moves heavy injection molds within a compact press cell, saving axial footprint while delivering 4934.8 N at 0.7 MPa to seat the tooling symmetrically.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X50 the Right Cylinder?
When sizing this 100 mm bore model, compare its 3524.9 N @0.5 MPa output with the neighboring SDAD80, which provides 2267.8 N @0.5 MPa. Stepping up to this 100 mm bore gives a massive 55% increase in thrust, making it necessary for high-mass displacement, whereas the 80 mm version suits lighter frames. This specific SKU features female M18x1.5 rod-end threads and lacks a piston magnet, meaning it cannot support magnetic sensing without switching to an -S variant.
The through-rod design provides excellent anti-rotation resistance and dual-end mounting flexibility for complex tooling. Remember that a plain cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. For vertical lifting applications requiring a 2:1 safety margin, it can handle approximately 179.7 kg, but you must integrate an external rod lock or pilot-operated check valve to secure the load mechanically.
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 SDAD100X50 FAQ
The SDAD100X50 delivers equal force in both directions due to its double-rod design: 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.
Yes, the 32 mm through-rod protrudes from both ends, allowing you to mount tooling on one side and a tracking fixture on the other while resisting rotation. However, this specific SKU lacks a piston magnet, so it cannot accept magnetic switches unless you upgrade to the -S variant.
