Airtac SED Double Rod Cylinder SED63X95
The AirTAC Airtac SED Double Rod Cylinder SED63X95 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 95mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X95
The AirTAC SED63X95 is a double-acting, double-rod ISO 15552 profile cylinder with a 63mm bore and 95mm stroke. Because a 20mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding a perfectly symmetrical 1402 N of force each way at 0.5 MPa. The extruded aluminum barrel integrates sensor grooves, though this specific SKU lacks the -S magnet option for position sensing. Field-adjustable air cushions at both ends (36mm cushion length) manage end-of-stroke deceleration.
The through-rod design is highly beneficial for applications requiring dual-side work or anti-rotation guidance. You can mount a cam or secondary tool on the rear rod end while the front drives the primary load. It uses a PT3/8 port and an M16x1.5 rod-end thread. Remember that the overall length is longer than a single-rod SE cylinder, so you must leave physical clearance for the rear rod to protrude safely.

| 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 |

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 SED63X95 Is Used
Multi-Station Indexing
Drives a 95mm stroke indexing dial with 1402 N both ways, using the rear rod to mount a synchronization cam for coordinated station timing.
Web Guiding Mechanism
Provides equal push and pull force to steer material webs, leveraging the twin rods to prevent binding and maintain parallel tracking.
Dual-Side Press Tooling
Actuates a small press where the front rod stamps parts and the rear rod simultaneously triggers an ejection sequence.
Is the Airtac SED Double Rod Cylinder SED63X95 the Right Cylinder?
When sizing this 63mm bore, stepping down to the 50mm bore drops the both-way output to 825 N at 0.5 MPa, while stepping up to the 80mm bore raises it to 2268 N. Choose this SED63X95 over a single-rod SE when your mechanism needs strict anti-rotation control, dual-side actuation, or a rear-mounted limit flag. As a true ISO 15552 profile cylinder, it drops into standard double-rod mounting interfaces using Basic, FA, LB, TC, FTC, TCM1, or TCM2 attachments (omitting FB, CA, CB, CR styles). Ensure you match the bore, 95mm stroke, PT3/8 port, and mounting style for a direct replacement. Note that a plain SED will drift on air loss; the adjustable cushion decelerates near stroke end but does not lock. For fail-safe holding, use a BSED double-rod rod lock or external brake.
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 SED63X95 FAQ
The SED63X95 generates 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa. Because it is a double-rod cylinder, this force is identical in both the extend and retract directions.
The twin rods provide superior anti-rotation guidance and allow tooling or sensors to be mounted on the rear rod end. It is dimensionally interchangeable per ISO 15552, but requires rear-rod clearance and uses a subset of mounts (Basic, FA, LB, TC, FTC, TCM1, TCM2).
