Airtac SED Double Rod Cylinder SED80X65
The AirTAC Airtac SED Double Rod Cylinder SED80X65 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 65mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X65
The AirTAC SED80X65 is a double-acting, double-rod ISO 15552 profile cylinder. A 25 mm rod exits both end covers, yielding identical annulus areas. This means you get exactly 2268 N of thrust and pull at 0.5 MPa, with no directional force mismatch.
It uses a PT3/8 port and 36 mm adjustable air cushions at both ends. Because this SKU lacks the -S magnet option, it has no onboard position sensing. The rear rod end is perfect for mounting a secondary cam or tooling fixture.
Airtac SED Double Rod Cylinder SED80X65 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X65 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 65 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 SED80X65 Is Used
Servo Press Mid-Stroke Stop
Provides 2268 N of equal both-way force at 0.5 MPa to halt a moving press platen without rotational drift.
Multi-Stage Forming Clamp
Uses the twin 25 mm rods to guide a heavy stamping fixture, resisting side loads during metal deformation.
Dual-Side Shuttle Transfer
Drives a 65 mm shuttle stroke while simultaneously moving a rear cam to trigger a downstream pneumatic valve.
Is the Airtac SED Double Rod Cylinder SED80X65 the Right Cylinder?
Choose this 80 mm bore for 2268 N both-way force at 0.5 MPa. If you need less force, step down to the 63 mm bore (1402 N both ways). For heavier drives, step up to the 100 mm bore (3681 N both ways).
A double rod prevents load rotation better than a single-rod SE cylinder. It also lets you mount tooling on the rear extension. Remember: air cushions only decelerate near stroke end; they do not hold position on air loss. For fail-safe holding, use an external BSED rod lock.
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 SED80X65 FAQ
Because the double rod occupies both piston sides, force is identical in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
Yes. It is a true ISO 15552 profile cylinder dimensionally interchangeable with other ISO 15552 double-rod units. Just match the 80 mm bore, 65 mm stroke, PT3/8 port, and your mounting type (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
