Airtac SED Double Rod Cylinder SED50X650S
The AirTAC SED Double Rod Cylinder SED50X650S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 650mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X650S
The AirTAC SED50X650S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. A 20 mm rod extends from both end covers, yielding an identical annulus area on both sides. This means you get exactly 825 N of thrust and pull each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in for any ISO 15552 double-rod footprint.
Equipped with a standard magnet (-S), this unit directly accepts CMSE reed or DMSE electronic sensors in the integrated barrel groove. Field-adjustable air cushions at 30 mm length protect the end caps across the 650 mm travel. The rear protruding rod can mount a secondary cam or sensor flag, synchronizing a secondary motion without needing a separate actuator.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 650 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| 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, 30 mm |
| Max stroke | Up to 1200 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SED50X650S Is Used
Cross-Sortation Pusher
Drives a dual-sided sorting arm on a packaging conveyor, using the equal 825 N both-way force to positively push and retract cartons without speed variation.
PCB Edge-Trimming Station
Feeds a cutting tool via the rear rod while the front rod clamps the board, leveraging the anti-rotation twin-rod design for accurate 650 mm travel.
Glass Panel Transfer
Shuttles delicate glass between processing stations, using the -S magnet and DMSE sensors to confirm exact mid-stroke positioning without collision.
Is the Airtac SED Double Rod Cylinder SED50X650S the Right Cylinder?
At 0.5 MPa, this 50 mm bore yields 825 N equally in both directions. If your load demands less force, step down to the 40 mm bore for 528 N; if you need more thrust, step up to the 63 mm bore for 1402 N. Choose this double-rod SED over a single-rod SE when the application requires anti-rotation guidance, equal push-pull dynamics, or rear-rod tooling. The twin rods resist torsional twisting better than a single rod, which is critical over long strokes.
Because this stroke is 650 mm, external linear guides are strongly recommended to prevent side-loading from sagging or heavy masses. A plain SED will drift upon air loss; the adjustable cushion only decelerates near stroke end and does not lock the piston. For fail-safe holding, specify a BSED double-rod lock or an external pilot-operated check valve. When replacing an existing ISO 15552 unit, match the 50 mm bore, 650 mm stroke, PT1/4 port, and mounting style (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 SED50X650S FAQ
Because the double-rod design subtracts rod area from both sides, force is identical in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. Just match the PT1/4 port, 650 mm stroke, and your mounting type (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Remember to leave rear-rod clearance, as a rod protrudes from both ends.
