Airtac SED Double Rod Cylinder SED63X140
The AirTAC SED Double Rod Cylinder SED63X140 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 140mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X140
The AirTAC SED63X140 is a double-acting, double-rod ISO 15552 profile cylinder featuring an extruded aluminum barrel. A piston rod extends from both end covers, yielding identical annulus areas on each side. This geometry delivers exactly 1402 N of output force at 0.5 MPa in both extend and retract directions (1962 N at 0.7 MPa).
Because a rod protrudes from the rear, you can mount a cam or secondary tooling on the opposite end while utilizing the PT3/8 port and M16x1.5 rod thread. This specific SKU lacks the -S magnet option, meaning it carries no onboard position sensing. Field-adjustable air cushions at both ends protect components near the 140 mm stroke limits.
Airtac SED Double Rod Cylinder SED63X140 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X140 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 140 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 SED63X140 Is Used
Web Guiding Mechanism
Drives opposing nip rollers with 1962 N at 0.7 MPa, using the twin rods to prevent binding and maintain precise web tracking.
Transfer Arm Indexer
Moves parts between stations where the rear rod end mounts a cam, leveraging equal push and pull forces for balanced cycling.
Spot Welding Clamp
Applies 1402 N of clamping force at 0.5 MPa on both stroke ends, ensuring consistent electrode pressure during automated welding.
Is the Airtac SED Double Rod Cylinder SED63X140 the Right Cylinder?
Choosing this 63 mm bore provides a balanced 1402 N both-way force at 0.5 MPa. If your application requires less force, the 50 mm bore offers 825 N. For heavier loads, the 80 mm bore provides 2268 N. Unlike a single-rod SE cylinder, this double-rod design prevents piston rotation and supports twin loads. Remember that a plain SED cannot hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end. For fail-safe holding, specify a BSED or an external lock. To replace an existing ISO 15552 unit, match the 140 mm stroke, PT3/8 port, and mounting subset (Basic, FA, LB, TC, FTC, TCM1, 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 SED63X140 FAQ
The double-rod design provides equal force 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.
A rod exits both ends, creating equal extend and retract forces. It offers superior anti-rotation guidance and allows rear-rod tooling or cam mounting, which a single-rod SE cannot do.
