Airtac SED Double Rod Cylinder SED63X900
The AirTAC Airtac SED Double Rod Cylinder SED63X900 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 900mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X900
The AirTAC SED63X900 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 20 mm rod exits both end covers, the effective piston area is identical in each direction. This means you get exactly 1402 N of output force at 0.5 MPa on both extend and retract strokes.
With a 900 mm stroke, this unit provides extended travel while maintaining an extruded aluminum barrel free of external tie rods. It features field-adjustable air cushioning at both ends to decelerate the load near stroke end. Note that this specific SKU lacks a magnet, so it cannot host CMSE or DMSE position sensors without modification.

| Configuration | Double rod, double acting |
| 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 SED63X900 Is Used
Web Guiding in Roll-to-Roll Printing
Provides 1402 N of equal both-way force at 0.5 MPa to tension and steer paper webs, using the rear rod to mount a mirror flag for edge tracking.
Pallet Transfer Pusher
Drives a 900 mm stroke to push heavy pallets between parallel conveyors, relying on the twin rods to resist twisting from asymmetric crate weights.
Multi-Spindle Drill Head Indexer
Shifts a drilling fixture 900 mm across an automotive machining line, benefiting from the anti-rotation properties of the dual-rod layout for precise spindle alignment.
Is the Airtac SED Double Rod Cylinder SED63X900 the Right Cylinder?
Stepping up or down in bore size changes your force profile significantly. If 1402 N at 0.5 MPa is too much, the next size down is the 50 mm bore providing 825 N both ways. If you need more push, the 80 mm bore yields 2268 N. At 900 mm of travel, the extended rod length makes the cylinder susceptible to side loads; always use external guide rails to prevent binding and premature seal wear.
Unlike a single-rod SE cylinder, the twin-rod design prevents the piston from rotating under offset loads and allows mounting a cam or secondary tool on the rear rod end. Remember that standard air cushions only decelerate the load; they do not hold position on air loss. For fail-safe holding, consider a BSED double-rod lock cylinder. When replacing an ISO 15552 unit, match the 63 mm bore, 900 mm stroke, PT3/8 port, and mounting interface (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 SED63X900 FAQ
The double-rod design provides equal force in both directions because the rod occupies both sides of the piston. It delivers 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 offer superior resistance to rotation under offset loads and allow you to mount tooling or a sensor flag on the rear rod end. It also shares the exact ISO 15552 mounting footprint and PT3/8 port of the standard SE series.
