Airtac SDAD Double Rod Slim Cylinder SDAD100X50S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X50S 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 SDAD100X50S
The AirTAC SDAD100X50S is a double-acting compact cylinder featuring a 100mm bore and a 50mm stroke. Because the 32mm piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 3524.9 N at 0.5 MPa in either direction. The short body design drastically reduces axial mounting depth compared to conventional round-body units.
Equipped with a built-in magnet (-S), this unit interfaces directly with AirTAC reed or electronic switches for position feedback. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. With a safe working load around 2115 N (roughly 60% of the 0.5 MPa rating), it supports vertical lifts up to 179.7 kg with a 2:1 safety margin.
Airtac SDAD Double Rod Slim Cylinder SDAD100X50S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X50S |
|---|---|
| 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 SDAD100X50S Is Used
Heavy-Duty Stamping Press
Drives a symmetric stamping die where the equal 3524.9 N push and pull forces prevent tool binding during high-force metal forming operations.
Vertical Lift Platform
Elevates a 179.7 kg payload using the through-rod design to resist twisting, while the dual-end rods maintain stable vertical guidance.
Dual-End Transfer Unit
Mounts a gripping jaw on one rod end and a magnetic switch dog on the opposite end, utilizing the compact riveted body to save axial space.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X50S the Right Cylinder?
When sizing this 100mm bore model, compare it against the adjacent SDAD80, which yields 2267.8 N at 0.5 MPa. Stepping up to this SDAD100X50S provides 3524.9 N at 0.5 MPa, peaking at 4934.8 N at 0.7 MPa and a theoretical 719 kgf at 1.0 MPa. It features a PT3/8 port, female M18x1.5 rod-end threads, and the -S magnet for sensing. Remember that the fixed NBR bumper only decelerates the stroke end; it does not function as a lock.
The through-rod design inherently resists twisting, allowing you to mount a work tool on one end and a position dog on the opposite side. Note that a standard double-acting cylinder cannot hold a load if air pressure drops or the valve centers—the piston will drift. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SDAD100X50S FAQ
The double-rod design provides equal force in both directions: 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 operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, a standard double-acting cylinder drifts when air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke end and acts as neither a brake nor a lock. For load holding, you must add an external rod lock or a pilot-operated check valve.
