Airtac SED Double Rod Cylinder SED63X185S
The AirTAC SED Double Rod Cylinder SED63X185S 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 185mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X185S
The AirTAC SED63X185S is a double-acting, double-rod profile cylinder conforming to ISO 15552. A 20mm rod exits both end covers, yielding identical annulus areas and exactly 1402N of thrust in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods, and adjustable air cushions at both ends decelerate the 185mm stroke.
Fitted with a magnet (-S), this 63mm bore unit supports CMSE reed and DMSE electronic sensors via integrated barrel grooves. The protruding rear rod provides superior anti-rotation guidance and can mount a secondary cam or flag, though you must leave rear clearance to accommodate the through-rod length.
Airtac SED Double Rod Cylinder SED63X185S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X185S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 185 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 SED63X185S Is Used
Servo-Driven Shuttle
Drives an alternating parts shuttle in an assembly line, utilizing the equal 1402N both-way force and rear rod for a synchronized secondary pick.
Web Edge Guide
Guides a material web edge in a converting slitter, using the twin rods to prevent binding and maintain precise tracking under 0.5 MPa.
Indexing Gate
Actuates a heavy-duty sorting gate on a packaging conveyor, relying on the anti-rotation properties of the dual rods to prevent jamming.
Is the Airtac SED Double Rod Cylinder SED63X185S the Right Cylinder?
This 63mm bore generates 1402N both ways at 0.5 MPa. If your payload is lighter, step down to the 50mm bore for 825N; if heavier, step up to the 80mm bore for 2268N. Choose this double-rod SED over a single-rod SE when your mechanism requires equal push-pull dynamics, dual-side load guidance, or rear-mounted position sensing.
For direct replacement, match the 63mm bore, 185mm stroke, PT3/8 port, and your mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that air pressure loss will cause drift; this cylinder does not hold position. Use an external pilot-operated check valve or the BSED double-rod lock for fail-safe holding. At 185mm stroke, external guide rails are recommended to manage side loads on the 20mm rod.
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 SED63X185S FAQ
Because the double-rod design subtracts the rod area on both sides, force is equal in both directions: 1402N at 0.5 MPa, 1962N at 0.7 MPa, with a maximum of 286 kgf at 1.0 MPa.
The twin rods provide superior anti-rotation guidance for the load and allow you to mount a rear cam or sensor flag. It is dimensionally interchangeable per ISO 15552, though the overall length is longer to clear the rear rod.
