Airtac SED Double Rod Cylinder SED80X145S
The AirTAC Airtac SED Double Rod Cylinder SED80X145S 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 145mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X145S
The AirTAC SED80X145S is a double-acting, double-rod profile cylinder conforming to the ISO 15552 interface. Because a 25 mm rod occupies both faces of the piston, the annulus area is symmetrical, yielding a perfectly equal 2268 N of thrust in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods for a clean profile.
Equipped with the -S magnet option, this unit supports DMSE electronic and CMSE reed sensors for dual-end position feedback. Field-adjustable air cushions at both ends absorb kinetic energy near stroke limits, while the rear rod extension can mount a secondary cam or sensor flag to sequence auxiliary operations.
Airtac SED Double Rod Cylinder SED80X145S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X145S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 145 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 SED80X145S Is Used
Web Guiding Mechanism
Provides 2268 N of equal bidirectional force to straighten and steer material webs without rotational deflection.
Dual-End Transfer Pusher
Drives a product transfer gate while the rear rod simultaneously triggers a downstream diverter cam.
Multi-Spindle Drill Head
Uses the twin 25 mm rods for anti-rotation guidance during precision drilling operations at 0.7 MPa.
Is the Airtac SED Double Rod Cylinder SED80X145S the Right Cylinder?
When sizing this 80 mm bore, stepping down to the 63 mm variant drops your both-way force to 1402 N at 0.5 MPa, whereas moving up to the 100 mm bore provides 3681 N. The SED80X145S is chosen over a single-rod SE when a mechanism demands high resistance to torsional side-load or requires driving a secondary assembly from the rear rod end. Remember that the adjustable cushion only decelerates the load; it will not hold position upon air loss. For fail-safe holding, specify a BSED double-rod lock or an external pilot check valve. To replace an existing ISO 15552 unit, match the 145 mm stroke, PT3/8 port, and mounting style from the SED set: 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 SED80X145S 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.
The twin rods exiting both ends prevent the piston from twisting under offset loads, and the rear rod can drive a secondary mechanism or sensor flag. It uses a 25 mm rod with an M20x1.5 thread and maintains ISO 15552 mounting interchangeability.
