Airtac SDAD Double Rod Slim Cylinder SDAD20X60
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X60 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø20mm bore, 60mm 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 SDAD20X60
The AirTAC SDAD20X60 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 remains identical in each direction, giving you exactly 131.9 N of push and pull force at 0.5 MPa. This symmetry is essential when driving loads that require consistent momentum in both strokes.
With a 60 mm stroke and an 8 mm rod diameter, this unit saves valuable axial mounting depth compared to standard round-body options. It uses a fixed NBR bumper at each end to decelerate the stroke end, rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD20X60 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X60 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 60 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 SDAD20X60 Is Used
Gripper Synchronization
Drives opposing gripper jaws with equal 131.9 N force in both directions, ensuring perfectly centered clamping on delicate machined parts.
Dual-End Transfer
Mounts a pusher on the front rod and a tracking dog on the rear rod, utilizing the anti-rotation geometry to move items smoothly between conveyor belts.
Symmetric Lifting Jig
Lifts and lowers a 6.7 kg fixture with a 2:1 margin, relying on the matched annular areas to prevent sagging during vertical transit.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X60 the Right Cylinder?
When sizing this model, compare it against its neighbors: the smaller SDAD16 yields 86.4 N at 0.5 MPa, while the larger SDAD25 provides 206.2 N. The SDAD20X60 hits a reliable middle ground, offering a safe working load of roughly 79 N (about 60 percent of its 131.9 N capacity) and a vertical lift capability of approximately 6.7 kg with a 2:1 safety margin.
The through-rod design inherently resists twisting, allowing you to mount a tool on one end and a dog on the opposite side. Remember that a plain cylinder drifts if air pressure drops or the valve centers, as the fixed bumper only decelerates near stroke end and acts purely as a bumper, never a lock. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration features a 20 mm bore, 60 mm stroke, M5x0.8 port, and female M4x0.7 rod-end threads.
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 SDAD20X60 FAQ
The SDAD20X60 generates 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical maximum of 27 kgf at 1.0 MPa. Because it is a double-rod cylinder, these force figures are exactly the same in both the extend and retract directions.
No, this specific SKU does not include a piston magnet, so it cannot accept reed or electronic switches. You would need the SDAD20X60S variant to utilize the body sensor grooves for position detection.
