Airtac SED Double Rod Cylinder SED63X165
The AirTAC SED Double Rod Cylinder SED63X165 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 165mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X165
The AirTAC SED63X165 is a double-acting, double-rod profile cylinder built to the ISO 15552 / VDMA 24562 dimensional interface. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 1402 N of force each way at 0.5 MPa. The extruded aluminum barrel omits external tie rods for a clean profile.
This 63mm bore unit uses a PT3/8 port, a 20mm rod with an M16x1.5 thread, and features field-adjustable air cushions at both ends. It carries no standard magnet (-S omitted), so no CMSE or DMSE sensors can be fitted to this SKU.

| 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) |

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 SED63X165 Is Used
Multi-Station Indexing
Provides 1402 N of equal both-way force to push and pull a multi-station dial indexer, using the rear rod to mount a physical cam for confirming cycle completion.
Dual-Side Transfer
Drives a conveyor transfer arm with 1962 N at 0.7 MPa, leveraging the through-rod to synchronize dual pusher plates on opposite sides of the belt.
Glass Edge Guiding
Applies equal push and pull pressure for 286 kgf max load to guide flat glass sheets through a washing machine, preventing twist via twin-rod anti-rotation.
Is the Airtac SED Double Rod Cylinder SED63X165 the Right Cylinder?
Choose this 63mm model for 1402 N both-way force at 0.5 MPa. If you need less output, step down to the 50mm bore for 825 N; if your mechanism requires more power, step up to the 80mm bore for 2268 N. The twin-rod layout is preferred over a single-rod SE when you need to mount a rear cam, drive a secondary mechanism, or guide the load against rotation.
At 165mm stroke, side-loading is moderate, but external guides are recommended if heavy loads are moved. Remember that a plain SED does not hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end. For fail-safe holding, select a BSED double-rod lock or an external rod lock.
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 SED63X165 FAQ
Because the double-rod design has equal piston areas on both sides, it generates 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa in both extend and retract directions.
Yes, the SED63X165 is a true ISO 15552 profile cylinder with no external tie rods. It offers dimensional interchangeability with other ISO 15552 double-rod cylinders, using a PT3/8 port and mounting options like FA, LB, and TC.
