Airtac SED Double Rod Cylinder SED63X650S
The AirTAC SED Double Rod Cylinder SED63X650S 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 650mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X650S
The AirTAC SED63X650S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. A 20mm rod exits both end covers, yielding equal effective areas. This means the cylinder generates 1402N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods, and the -S magnet enables position sensing.
Equipped with field-adjustable air cushioning at both ends (36mm cushion length), it safely decelerates the tooling over the 650mm stroke. The PT3/8 port and M16x1.5 rod-end thread handle the required 30-800 mm/s speed range. The rear rod protrusion is perfect for mounting a secondary cam or limit flag to track the opposite end of the stroke.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 650 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 SED63X650S Is Used
Web Guiding Mechanism
Drives a dancer roller in a film slitting machine. The twin rods provide anti-rotation stability for the 1402N load, while the rear rod mounts a DMSE sensor flag to track web tension.
Pallet Transfer Pusher
Pushes heavy pallets onto an adjacent packaging line. The equal 1962N force at 0.7 MPa ensures consistent extend and retract speed without requiring pressure compensation.
CNC Lathe Loader
Actuates a dual-grip parts loader for a CNC lathe. The 650mm stroke moves bar stock, and the rear rod end drives a secondary mechanical cam to time the chuck open sequence.
Is the Airtac SED Double Rod Cylinder SED63X650S the Right Cylinder?
When sizing this unit, note the 63mm bore provides 1402N both ways at 0.5 MPa. If your application requires less force, step down to the 50mm bore (825N both ways). For heavier drives, step up to the 80mm bore (2268N both ways). Because the stroke is 650mm, ensure external load guides are used to prevent side-loading damage to the rod seals and front cap.
Choose this double-rod SED over a single-rod SE when you need superior anti-rotation guidance, twin load driving, or rear-position sensing. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Note that the air cushion only decelerates near stroke end; it does not hold position on air loss. For fail-safe holding, use a BSED double-rod lock or external pilot check valve.
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 SED63X650S FAQ
Because the double-rod design yields equal effective piston areas on both sides, the force is identical in both directions: 1402N at 0.5 MPa, 1962N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
Yes. The SED63X650S shares ISO 15552 / VDMA 24562 mounting interface dimensions, making it a direct replacement for other ISO 15552 double-rod profile cylinders. Just verify your rear-rod clearance, as the rod exits both ends.
