Airtac SDAD Double Rod Slim Cylinder SDAD20X10
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X10 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø20mm bore, 10mm 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 SDAD20X10
The AirTAC SDAD20X10 is a double-acting compact 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 an equal push and pull force of 131.9 N at 0.5 MPa. This symmetry is ideal for driving loads that require consistent kinetic output without twisting.
With a mere 10 mm stroke and an 8 mm rod diameter, this thin profile saves axial mounting depth where a standard round-body unit will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD20X10 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X10 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 10 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 90 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 (Ø20mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 SDAD20X10 Is Used
Strip Peeling
Drives a short 10 mm blade stroke to peel adhesive strips, using the equal 131.9 N push and pull force to maintain consistent tension without twisting.
PCB Ejection
Uses the compact riveted body to fit tight electronics assembly cells, pushing a board out one end while a dummy rod idles on the other.
Symmetric Clamping
Clamps a delicate workpiece from both sides simultaneously via the through-rod, ensuring perfectly balanced 131.9 N holding force in both directions.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X10 the Right Cylinder?
When sizing this 20 mm bore unit, consider the neighbouring bores: stepping down to the SDAD16 provides 86.4 N at 0.5 MPa, while stepping up to the SDAD25 yields 206.2 N at 0.5 MPa. The through-rod geometry resists rotation, allowing you to mount a work tool on one end and a dog on the opposite end simultaneously. A safe working load is roughly 79 N, providing a 2:1 margin for a vertical lift of about 6.7 kg.
This configuration uses an M5x0.8 port and female M4x0.7 rod-end threads on both sides. Note that a plain cylinder drifts when air is lost or the valve is centred; the NBR bumper only decelerates near the stroke end and acts as no brake. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
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 SDAD20X10 FAQ
The double-rod design provides equal force in both directions: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical maximum of 27 kgf at 1.0 MPa.
Yes, the through-rod resists rotation and allows dual-end mounting. However, this specific SKU lacks a piston magnet, so position sensing requires upgrading to the -S variant for AirTAC reed or electronic switches.
