Airtac SED Double Rod Cylinder SED50X35
The AirTAC SED Double Rod Cylinder SED50X35 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 35mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X35
The AirTAC SED50X35 is a double-acting, double-rod ISO 15552 profile cylinder. A 20mm rod exits both end covers, yielding identical annulus areas. It delivers exactly 825 N of thrust and pull at 0.5 MPa, ensuring perfectly symmetrical force both ways.
This 50mm bore unit features a PT1/4 port and 30mm adjustable air cushions at both ends. It lacks a standard magnet, meaning external sensors are incompatible. The rear rod extension is perfect for mounting a cam or secondary tool, but requires dedicated clearance.
Airtac SED Double Rod Cylinder SED50X35 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED50X35 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 35 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| 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, 30 mm |
| Max stroke | Up to 1200 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SED50X35 Is Used
Web Guiding Mechanism
Uses the 825 N equal both-way force to precisely tension and steer film webs without rotational deflection.
Dual-Side Transfer Chuck
Transfers small electronic parts between stations using both rod ends for synchronized gripping.
Cam-Indexing Unit
Leverages the rear rod protrusion to actuate a mechanical cam while the front rod drives the primary press.
Is the Airtac SED Double Rod Cylinder SED50X35 the Right Cylinder?
Choose this 50mm bore when you need equal 825 N force in both directions at 0.5 MPa. If your application requires less power, step down to the 40mm bore (528 N). For heavier drives, step up to the 63mm bore (1402 N). The twin-rod design prevents load rotation better than a single-rod SE cylinder.
This unit is dimensionally interchangeable per ISO 15552. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Note that standard air cushions only decelerate near stroke end; they do not hold position on air loss. For fail-safe holding, consider a BSED rod lock cylinder.
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 SED50X35 FAQ
Because the rod occupies both sides of the piston, force is equal in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
Yes. It is a true ISO 15552 profile cylinder with no external tie rods, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. Just ensure you have rear-rod clearance.
