Airtac SED Double Rod Cylinder SED63X275
The AirTAC SED Double Rod Cylinder SED63X275 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 275mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X275
The AirTAC SED63X275 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. Because a Ø20 mm rod extends from 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.
This SKU has no standard magnet, so it does not support CMSE or DMSE position sensing without modification. The extruded aluminum barrel incorporates adjustable air cushions at both ends to tame kinetic energy near stroke extremes. You must leave rear-rod clearance in your layout, as the piston rod protrudes from the back cover.
Airtac SED Double Rod Cylinder SED63X275 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 275 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 SED63X275 Is Used
Web Guiding Brakes
Drives opposing brake shoes on a film converting line. The equal 1402 N both-way force ensures symmetric tensioning without skewing the web path.
Parallel Pick-and-Place
Moves a dual-jaw gripper on an electronics assembly handler. The rear rod simultaneously pushes a limit flag to confirm stroke completion.
Lift-and-Transfer Gates
Actuates a vertical gate on a packaging conveyor. The twin rods prevent the load from binding during the 275 mm vertical lift cycle.
Is the Airtac SED Double Rod Cylinder SED63X275 the Right Cylinder?
Choose this 63 mm bore when you need 1962 N of force at 0.7 MPa in both directions. If your load is lighter, step down to the 50 mm bore which yields 825 N at 0.5 MPa. For heavier drives, step up to the 80 mm bore providing 2268 N at 0.5 MPa. The twin-rod design inherently resists torsion better than a single-rod SE cylinder, making it ideal for dual-side guidance and rear-rod cam actuation.
At 275 mm of stroke, the extended rod length amplifies any lateral load. Use external guide rails to prevent side-loading damage to the front and rear bushings. Remember that a plain SED does not hold position on air loss; the piston will drift. For fail-safe holding, use a BSED double-rod lock or an external pilot-operated check valve. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and 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 SED63X275 FAQ
Because the rod occupies 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 SED63X275 is a profile cylinder with ISO 15552 / VDMA 24562 mounting dimensions, making it a direct replacement. Just match the PT3/8 port, M16x1.5 rod thread, and your chosen mounting style.
