Airtac SED Double Rod Cylinder SED80X475
The AirTAC Airtac SED Double Rod Cylinder SED80X475 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 475mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X475
The AirTAC SED80X475 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 475 mm stroke and an 80 mm bore. Because a 25 mm rod exits both end covers, the effective piston area is identical in both directions. This yields exactly 2268 N of thrust and pull at 0.5 MPa, ensuring perfectly balanced motion for demanding transfer operations.
The extruded aluminum barrel omits external tie rods for a clean profile. Field-adjustable air cushions at 36 mm lengths decelerate the load near each stroke end. This specific SKU lacks the -S magnet option, meaning it has no onboard position sensing; integrate external limit switches for end-of-stroke detection.
Airtac SED Double Rod Cylinder SED80X475 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X475 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 475 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 SED80X475 Is Used
Pallet Transfer Strapper
Drives a strapping head on a pallet line using the 2268 N both-way force to feed and retract the strap equally, preventing slip on heavy wood pallets.
Servo Press Leveler
Uses the twin 25 mm rods to guide a leveling plate against rotation, ensuring metal sheets enter the press straight without binding.
Gantry Pick-and-Place
Couples the rear rod end to a secondary cam, synchronizing a gripper jaw while the front rod lifts 463 kgf of engine blocks at 1.0 MPa.
Is the Airtac SED Double Rod Cylinder SED80X475 the Right Cylinder?
When sizing this 80 mm bore, note the 50 mm bore provides 825 N both ways at 0.5 MPa, while the 100 mm bore jumps to 3681 N. Choose this 80 mm model when your mechanism needs 2268 N of symmetric force to drive a rear-rod cam or secondary mechanism. For drop-in replacements, match the 475 mm stroke, PT3/8 port, and mounting from the SED set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. At 475 mm stroke, the extended rod length demands external linear guides to prevent side-load wear on the end covers. A plain SED does not hold position on air loss; the piston drifts and the cushion only decelerates, so specify a BSED double-rod 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 SED80X475 FAQ
Because the double-rod design subtracts the rod area on both sides, force is equal 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.
No. The SED ISO 15552 mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR mounts found on some single-rod cylinders to accommodate the rear rod protrusion.
