Airtac SED Double Rod Cylinder SED80X120S
The AirTAC Airtac SED Double Rod Cylinder SED80X120S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø80mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 120mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X120S
The AirTAC SED80X120S is a double-acting, double-rod ISO 15552 profile cylinder. A 25mm rod extends from both end covers, yielding identical annulus areas and equal force in both directions—2268N at 0.5MPa and 3175N at 0.7MPa.
Equipped with the -S magnet option, it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel includes sensor grooves, and field-adjustable air cushions at both ends decelerate the 30-800mm/s motion. Remember to leave rear-rod clearance, as the twin-rod design extends overall length beyond a single-rod SE cylinder.
Airtac SED Double Rod Cylinder SED80X120S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X120S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 120 mm |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SED80X120S Is Used
Servo Press Feeding
Drives a gripper carriage on a CNC servo press, using the 3175N bidirectional force and twin rods to prevent binding during rapid 30-800mm/s part indexing.
Glass Edge Seamer
Pushes a grinding spindle against flat glass edges. The equal both-way force ensures consistent polishing pressure whether extending or retracting.
Dual-Side Lift Gate
Actuates a heavy pneumatic lift gate from the center, using the rear rod end to mount a cam for a secondary latch mechanism.
Is the Airtac SED Double Rod Cylinder SED80X120S the Right Cylinder?
Choose this 80mm bore when you need 2268N of bidirectional force at 0.5MPa. If your load is lighter, the 63mm bore provides 1402N; for heavier drives, the 100mm bore offers 3681N. The twin rods prevent torsional twist and can drive a secondary mechanism from the rear. Note that air cushions only decelerate near stroke end; for fail-safe position holding on air loss, use a BSED rod lock or external pilot check valve. As a true ISO 15552 cylinder, it drops in for any standard double-rod footprint using PT3/8 ports and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
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 SED80X120S FAQ
Because the double-rod design creates equal piston areas on both sides, force is identical in both directions: 2268N at 0.5MPa, 3175N at 0.7MPa, and a maximum of 463kgf at 1.0MPa.
Yes. The SED80X120S is a profile cylinder dimensionally interchangeable per ISO 15552. It uses a PT3/8 port, a 25mm rod with M20x1.5 thread, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
