Airtac SDAD Double Rod Slim Cylinder SDAD20X60B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X60B 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 SDAD20X60B
The AirTAC SDAD20X60B is a double-acting compact cylinder featuring a 20 mm bore and 60 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry yields perfectly symmetrical thrust, generating 131.9 N at 0.5 MPa for both extend and retract strokes.
This specific SKU includes male M6x1.0 threaded rods on both ends for direct tool mounting. The short body design minimizes axial footprint, while the fixed NBR bumper decelerates the stroke ends. Operating pressure spans 0.15 to 1.0 MPa, and the M5x0.8 port ensures reliable airflow across the 30 to 500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD20X60B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X60B |
|---|---|
| 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 SDAD20X60B Is Used
Gripper Jaw Sync
Drives opposed gripper jaws where the male M6 thread mounts custom fingers and equal push/pull force keeps the jaws perfectly aligned.
Transfer Pusher
Pushes parts along a belt using the 60 mm stroke, benefiting from the anti-twist through-rod to maintain precise contact with the workpiece.
Flap Folder
Folds carton flaps symmetrically using both rod ends, saving axial depth inside tight packaging machinery frames.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X60B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to SDAD16 yields 86.4 N at 0.5 MPa, while stepping up to SDAD25 provides 206.2 N at 0.5 MPa. For this 20 mm bore, a safe working load is roughly 79 N (about 60 percent of the 131.9 N figure), which translates to a vertical lift capacity of approximately 6.7 kg with a 2:1 safety margin.
The through-rod design resists twisting and allows mounting a dog on the opposite end. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near stroke end and does not lock the load. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration lacks a piston magnet, so it cannot accept reed or electronic switches. To add sensing capabilities, specify the -S variant.
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 SDAD20X60B 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 you must select the -S variant to use AirTAC reed or electronic switches for position sensing.
