Airtac SED Double Rod Cylinder SED63X135S
The AirTAC SED Double Rod Cylinder SED63X135S 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 135mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X135S
The AirTAC SED63X135S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 135mm stroke. Because a 20mm rod exits both ends, the annular piston area is identical on extend and retract, yielding equal force of 1402 N each way at 0.5 MPa. The integrated -S magnet enables position tracking using CMSE reed or DMSE electronic sensors.
This through-rod design provides superior anti-rotation guidance for loads and allows the rear rod end to drive a secondary mechanism or mount a cam. It shares the SE extruded aluminum barrel and field-adjustable air cushions at both ends, but requires rear-rod clearance due to its longer overall length.
Airtac SED Double Rod Cylinder SED63X135S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X135S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 135 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 SED63X135S Is Used
Web Guiding Mechanism
Drives a paper or film web guide with 1402 N of equal both-way force, using the twin 20mm rods to prevent binding and maintain precise tracking without load rotation.
Dual-Side Parts Ejector
Ejects stamped metal parts from a press die, utilizing the rear rod to simultaneously push a confirmation sensor flag while the front rod clears the part.
Shuttle Transfer Unit
Transfers automotive components between stations, relying on the 135mm stroke and symmetrical thrust to accelerate and decelerate loads smoothly in both directions.
Is the Airtac SED Double Rod Cylinder SED63X135S the Right Cylinder?
Select the 63mm bore when your application demands 1402 N of symmetrical thrust at 0.5 MPa. If you need less force, step down to the 50mm bore providing 825 N both ways; if pushing heavier payloads, step up to the 80mm bore delivering 2268 N. The twin M16x1.5 rods excel at preventing load twist compared to a single-rod SE cylinder, while the rear rod can operate a secondary gate. For direct replacements, match the 135mm stroke, PT3/8 port, and mounting from the SED set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that air cushions only decelerate near stroke end; a plain SED drifts on air loss, so use a BSED rod lock for fail-safe holding.
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 SED63X135S FAQ
The double-rod design provides equal force in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
The twin rods provide superior anti-rotation guidance for the load and allow the rear rod to drive a secondary mechanism or cam. It also ensures identical extend and retract speeds, but requires extra rear clearance and omits FB, CA, CB, and CR mountings.
