Airtac SED Double Rod Cylinder SED63X85
The AirTAC Airtac SED Double Rod Cylinder SED63X85 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 SED63X85
The AirTAC SED63X85 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 1402 N of force at 0.5 MPa in both directions. This symmetry eliminates the push-pull force mismatch found in single-rod units.
This 63 mm bore unit features a PT3/8 port, a 20 mm rod with an M16x1.5 thread, and adjustable air cushions at both ends. The rear rod extension is perfect for mounting a cam or driving a secondary mechanism. Note that this specific SKU lacks a piston magnet, so it cannot host CMSE or DMSE position sensors.

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 SED63X85 Is Used
Web Guiding Brakes
Drives opposing brake shoes on a film winding line. The twin rods prevent shoe twisting, delivering 1402 N of perfectly equal clamping force in both directions.
Dual-Side Transfer Jaws
Actuates synchronized pick-and-place grippers on an electronics assembly line. The rear rod protrusion simultaneously drives a mechanical ejector cam.
Edge Deburring Fixtures
Clamps aluminum extrusions for robotic deburring. The rigid double-rod guidance absorbs lateral cutting loads without drifting under 0.5 MPa pressure.
Is the Airtac SED Double Rod Cylinder SED63X85 the Right Cylinder?
Choose this 63 mm bore if your application requires 1402 N (at 0.5 MPa) of perfectly balanced force in both directions. If you need less thrust, the adjacent 50 mm bore provides 825 N both ways; stepping up to the 80 mm bore yields 2268 N. The twin-rod design inherently resists torsion and provides superior anti-rotation guidance compared to a single-rod SE cylinder.
As a true ISO 15552 extruded-aluminum profile cylinder, it drops in seamlessly for any standard 63 mm double-rod replacement using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (FB/CA/CB/CR are omitted). Remember that adjustable air cushions only decelerate the load near stroke end; they do not hold position on air loss. For fail-safe locking, consider an external rod lock or the BSED series.
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 SED63X85 FAQ
Because the double-rod design occupies volume on both sides of the piston, 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.
Yes. The SED63X85 is an extruded aluminum profile cylinder with standard ISO 15552 mounting dimensions. You can directly swap it using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts, provided you leave clearance for the rear rod protrusion.
