Airtac SED Double Rod Cylinder SED63X85S
The AirTAC Airtac SED Double Rod Cylinder SED63X85S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø63mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 85mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X85S
The AirTAC SED63X85S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both end covers, the annulus area is identical on each side. This means you get exactly 1402 N of output force at 0.5 MPa in both extend and retract directions.
Equipped with a magnet (-S), this 63mm bore unit triggers CMSE reed or DMSE electronic sensors. The extruded aluminum barrel lacks external tie rods, and the field-adjustable air cushions at both ends decelerate the load smoothly before end-of-stroke impact.

| Port size | PT3/8 |
| Rod thread | M16×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 36 mm |

Specifications follow the official AirTAC SED datasheet and ISO 15552 / VDMA 24562 dimensions. Confirm against the product label before installation. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 kgf |
Because a rod exits both ends, the effective piston area — and therefore the force — is identical on extend and retract. Actual usable force is lower than theoretical; size with a safety margin.

Where the Airtac SED Double Rod Cylinder SED63X85S Is Used
PCB Lifting Jigs
Drives vertical pick-and-place jigs in electronics assembly. The twin rods prevent deflection on the 1402 N lift, while the rear rod end mounts a DMSE electronic sensor flag for precise height confirmation.
Indexing Gates
Actuates heavy material routing gates on conveyor lines. Equal 1962 N force at 0.7 MPa ensures positive seating in both directions without the speed imbalance seen in single-rod cylinders.
Dual-Side Clamping
Simultaneously clamps a workpiece from two opposite sides. The through-rod design allows the rear extension to drive a secondary mechanism, delivering matched 1402 N clamping pressure on both ends.
Is the Airtac SED Double Rod Cylinder SED63X85S the Right Cylinder?
Choose this 63mm bore if your process requires 1402 N at 0.5 MPa (or 1962 N at 0.7 MPa) equally in both travel directions. If you need less force, step down to the 50mm bore providing 825 N; if you need more, step up to the 80mm bore yielding 2268 N. The twin-rod design inherently resists torsional rotation better than a single-rod SE cylinder, making it ideal for guiding heavy vertical tooling.
A plain SED does not hold position upon air loss; the piston will drift. For fail-safe holding, specify a BSED double-rod rod lock or use an external pilot-operated check valve. To replace an existing ISO 15552 unit, match the 85mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Quick checklist
- ✓ Equal force/speed both directions needed?
- ✓ Back-rod space for tooling or a flag
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Support both rod ends; avoid side load.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SED Double Rod Cylinder SED63X85S FAQ
Because the double-rod design subtracts rod area from both piston sides, force is equal in both directions. It provides 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
The twin rods provide equal extend and retract forces, better anti-rotation stability for heavy loads, and a rear rod end that can mount a cam or sensor flag. It uses the standard ISO 15552 mounting interface but omits FB, CA, CB, and CR mounts.
