Airtac SED Double Rod Cylinder SED63X700S
The AirTAC SED Double Rod Cylinder SED63X700S 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 700mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X700S
The AirTAC SED63X700S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A 20mm rod extends from both end covers, yielding identical annulus areas. This means drive force is perfectly balanced at 1402 N in both directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods for a clean profile.
Equipped with a standard magnet (-S), it interfaces directly with CMSE reed and DMSE electronic sensors. Field-adjustable air cushions at both ends decelerate the piston near stroke extremes. Remember that this long 700mm stroke requires rear-rod clearance and external load guidance to prevent side-loading.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 700 mm |
| 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 |
| Max stroke | Up to 1500 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 SED63X700S Is Used
CNC Lathe Bar Puller
Drives a synchronized puller mechanism on CNC lathes. The 1402N both-way force securely extracts bar stock, while the rear rod simultaneously trips an external limit flag.
Pallet Transfer Pusher
Pushes heavy pallets across a transfer line. The twin 20mm rods prevent twisting during the 700mm extension, maintaining precise alignment under high dynamic loads.
Dual-Side Packaging Flap
Actuates dual cardboard flap folders on packaging machines. Equal extend and retract forces ensure simultaneous folding of both sides without mechanical binding.
Is the Airtac SED Double Rod Cylinder SED63X700S the Right Cylinder?
Selecting this 63mm bore provides a both-way force of 1402 N at 0.5 MPa. If your application needs less force, step down to the 50mm bore yielding 825 N both ways. For heavier loads, step up to the 80mm bore providing 2268 N. Compared to a single-rod SE, this twin-rod design offers superior anti-rotation stability and enables rear-rod tooling or cam actuation.
At 700mm, side loads are a primary concern; always use external guide rails to support the load. A plain SED will drift upon air loss, as the cushions only decelerate near stroke end and do not lock position. For fail-safe holding, specify a BSED double-rod lock or an external pilot-operated check valve. For a true ISO 15552 replacement, match the 63mm bore, 700mm stroke, PT3/8 port, and -S magnet option.
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 SED63X700S FAQ
Because the double-rod design creates equal piston areas on both sides, output force is identical in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
It provides equal force and speed in both directions, better load stability and anti-rotation compared to a single-rod SE cylinder, and allows rear-rod tooling or cam mounting. It is dimensionally interchangeable per ISO 15552.
