Airtac SDAD Double Rod Slim Cylinder SDAD20X60SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X60SB 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 SDAD20X60SB
The AirTAC SDAD20X60SB is a compact double-acting cylinder with a piston rod exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area is identical on extend and retract, yielding exactly 131.9 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balanced tooling, while the through-rod geometry inherently resists twisting.
This specific configuration includes a built-in magnet for AirTAC reed or electronic switches and male M6x1.0 rod threads on both ends. The 60 mm stroke operates within the 100 mm standard limit, and the short body saves axial mounting depth. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD20X60SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X60SB |
|---|---|
| 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 SDAD20X60SB Is Used
Symmetric Transfer Jaws
Drives gripper jaws that push and pull identical 131.9 N loads, utilizing the equal annular force to prevent uneven wear on precision guide rails.
Dual-End Profile Gauging
Mounts a machining fixture on the front male M6 rod and a magnetic switch dog on the rear, leveraging the anti-rotation through-rod for strict alignment.
Compact Strip Ejection
Fits within tight 20 mm bore footprint constraints to eject thin material strips, saving axial depth where a larger profile body cannot fit.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X60SB the Right Cylinder?
When sizing this unit, compare its 131.9 N @0.5 MPa output both ways: stepping down to the SDAD16 yields 86.4 N, while moving up to the SDAD25 provides 206.2 N. For your 20 mm bore, a safe working load is roughly 79 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 6.7 kg with a 2:1 safety margin. This model uses an M5x0.8 air port and male M6x1.0 rods at both ends.
The through-rod design allows driving a tool on one side while mounting a position dog on the opposite end. Note that a standard cylinder does not hold position if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a 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 SDAD20X60SB FAQ
The double-rod design provides equal force in both directions: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa. The theoretical maximum is 27 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod protrudes from both ends, allowing you to drive a tool on one side and mount a dog for an AirTAC reed or electronic switch on the other. This model includes the -S magnet and male M6x1.0 rod threads on both ends.
