Airtac SDAD Double Rod Slim Cylinder SDAD16X35S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD16X35S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø16mm bore, 35mm 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 SDAD16X35S
The AirTAC SDAD16X35S is a compact double-acting cylinder featuring a 16mm bore and 35mm stroke, with a 6mm piston rod exiting both ends of its short riveted body. Because a rod occupies each chamber, the annular area is identical in both directions, delivering an equal push and pull force of 86.4 N at 0.5 MPa. This symmetric output is ideal for balanced actuation tasks.
The through-rod geometry inherently resists twisting, while allowing you to drive a tool on one end and mount a dog on the opposite end. Equipped with a built-in magnet (-S), it supports AirTAC reed or electronic switches via the body sensor grooves. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD16X35S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD16X35S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 35 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø16mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 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 SDAD16X35S Is Used
Symmetric Transfer Shuttle
Drives a pick-and-place shuttle where the equal 86.4 N push and pull force prevents skewing during rapid part transfers.
Dual-End Probe Actuation
Mounts a testing probe on one rod end and a position dog on the opposite end, leveraging the anti-rotation through-rod for repeatable measurements.
Compact Component Sorting
Fits into tight 16mm bore machinery envelopes to push and pull lightweight diverters, using the short riveted body to save axial depth.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD16X35S the Right Cylinder?
When sizing this unit, compare its 86.4 N @0.5 MPa output both ways: stepping down to the SDAD12 yields 42.4 N, while moving up to the SDAD20 provides 131.9 N. For your design, a safe working load is roughly 52 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 4.4 kg with a 2:1 safety margin.
This configuration includes the -S magnet for position sensing and female M3x0.5 rod-end threads on both ends, with an M5x0.8 air port. Note that a plain cylinder drifts when air is lost or the valve centers, as the fixed bumper only decelerates near stroke end rather than locking the load; use an external rod lock or pilot-operated check valve for true load holding.
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 SDAD16X35S FAQ
Because the double-rod design provides equal annular area on both sides, the push and pull forces are identical: 86.4 N at 0.5 MPa, 121 N at 0.7 MPa, and a theoretical maximum of 18 kgf at 1.0 MPa.
Yes, the 6mm through-rod exits both ends to resist twisting, allowing you to mount a tool on one side and a dog on the other. The built-in -S magnet works with AirTAC reed or electronic switches in the body grooves for position feedback.
