Airtac SED Double Rod Cylinder SED50X700S
The AirTAC SED Double Rod Cylinder SED50X700S 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 700mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X700S
The AirTAC SED50X700S is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. A single piston drives a 20mm rod out of both end covers, yielding an identical annulus area on both sides. This design outputs an equal 825 N of force in both directions at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile.
Equipped with a standard magnet (-S), this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The rear rod extension is highly useful for mounting a secondary cam, operating a limit flag, or driving a secondary mechanism. Field-adjustable air cushions at both ends provide kinetic energy absorption near stroke extremes.

| 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 |

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 SED50X700S Is Used
Web Guiding Frames
Drives opposing edge-guide rollers on film or paper lines. The twin rods provide equal 825 N tensioning force both ways, keeping the web centered without rotational drift.
Dual-Side Transfer Chutes
Actuates synchronized diverters on packaging conveyors. The rear rod simultaneously pushes a secondary gate, moving both sides at exactly the same speed.
Glass Panel Lifters
Raises and lowers heavy glass handling fixtures. The double-ended design resists twisting loads during vertical transit, ensuring the panel remains perfectly level.
Is the Airtac SED Double Rod Cylinder SED50X700S the Right Cylinder?
With a 700mm stroke, the protruding rear rod requires careful machine layout to provide adequate clearance. At this length, side loads cause rod bending; always use external linear guides to prevent binding and premature seal wear. The 50mm bore yields 825 N both ways at 0.5 MPa. If you need less force, the 40mm bore provides 528 N both ways. If your load requires more, step up to the 63mm bore for 1402 N both ways.
Choose this double-rod configuration over a single-rod SE cylinder when your application demands high resistance to rotation or needs simultaneous actuation on two opposite sides. Remember that a standard cylinder does not hold position on air loss; the piston will drift. For fail-safe holding, specify a BSED double-rod lock or an external pilot-operated check valve. This direct ISO 15552 replacement matches a 50mm bore, 700mm stroke, PT1/4 port, and your required mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SED50X700S FAQ
Because a rod exits both ends, the effective piston area is identical in both directions. It delivers 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The twin rods offer superior resistance to side-load twisting and allow you to mount a rear cam or sensor flag. It also provides equal speed and force on extend and retract, which is critical for synchronized dual-side mechanisms.
