Airtac SDAD Double Rod Slim Cylinder SDAD32X85
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X85 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø32mm bore, 85mm 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 SDAD32X85
The AirTAC SDAD32X85 is a double-acting, double-rod compact cylinder engineered for symmetric actuation. Because the 12 mm piston rod exits both ends of the riveted body, the annular areas match, delivering an equal 345.6 N of push and pull force at 0.5 MPa. This geometric balance prevents twisting and provides a stable 85 mm stroke.
Its short footprint saves axial mounting depth compared to standard round-body units. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so position sensing is not supported without switching to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD32X85 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X85 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 85 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 120 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 (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 SDAD32X85 Is Used
Web Guiding Mechanism
Utilizes the anti-rotation through-rod to steer film or foil precisely, maintaining equal 345.6 N tension across the 85 mm travel.
Dual-End Transfer Gate
Drives a sorting flap on one side while a tracking dog rides the opposite rod end, benefiting from the compact body depth.
Symmetric Lift Platform
Raises and lowers a light 17.6 kg assembly fixture with matched push/pull dynamics to prevent binding during vertical transit.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X85 the Right Cylinder?
When sizing this 32 mm bore model, consider the neighbouring bores: the SDAD25 provides 206.2 N at 0.5 MPa, while the SDAD40 offers 527.8 N. The SDAD32X85 strikes a middle ground, yielding a safe working load of roughly 207 N (about 60% of its 345.6 N capacity) and a vertical lift capability near 17.6 kg with a 2:1 safety margin.
The through-rod design allows mounting a work tool on one end and a dog or fixture on the opposite end simultaneously. Remember that a plain cylinder drifts if air pressure drops; use an external rod lock or pilot-operated check valve for strict load holding. This configuration features an 85 mm stroke, a PT1/8 port, female M6x1.0 rod-end threads, and no magnet.
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 SDAD32X85 FAQ
The double-rod design provides equal force in both directions: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa. The theoretical maximum is 70 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the 12 mm through-rod protrudes from both sides, allowing you to drive a tool on one end and mount a dog on the other. This configuration lacks a magnet for switches, but the -S variant adds one for reed or electronic sensing.
