Airtac SED Double Rod Cylinder SED63X155S
The AirTAC SED Double Rod Cylinder SED63X155S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø63mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 155mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X155S
The AirTAC SED63X155S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 155mm stroke. Because a 20mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal 1402 N of thrust each way at 0.5 MPa. The extruded aluminum barrel omits external tie rods, ensuring clean integration and true ISO 15552 mounting interchangeability.
Fitted with the -S magnet option, this unit directly supports CMSE reed and DMSE electronic sensors for dual-end position tracking. Field-adjustable air cushions at both ends provide tailored deceleration over the 36mm cushion length, while the rear rod end can drive a secondary mechanism or carry a cam. Standard PT3/8 ports and an M16x1.5 rod thread facilitate straightforward pneumatic and mechanical connections.
Airtac SED Double Rod Cylinder SED63X155S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X155S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 155 mm |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| 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, 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SED63X155S Is Used
Servo-Driven Gripper Actuation
Provides 1402 N of equal both-way force to grip and release heavy castings, using the rear rod to sync a secondary cam without rotational drift.
Reciprocating Transfer Pushers
Drives a dual-sided conveyor sorting gate where the through-rod guarantees identical extend and retract speeds for matched cycle times.
Web Edge Guiding Mechanisms
Steers heavy film or foil webs with precise 155mm adjustments, leveraging the twin rods' anti-rotation properties to maintain parallel tracking.
Is the Airtac SED Double Rod Cylinder SED63X155S the Right Cylinder?
Select this 63mm bore when an application demands 1402 N of symmetrical push and pull force at 0.5 MPa. If your mechanism requires less force, stepping down to the 50mm bore provides 825 N both ways. If you need greater thrust, the 80mm bore provides 2268 N both ways. The twin-rod design is specifically chosen over a single-rod SE cylinder when the load requires high resistance to rotation, or when the rear rod must drive a secondary mechanism. Note that a plain SED does not hold position upon air loss; for fail-safe holding, consider a BSED rod-lock cylinder or an external pilot-operated check valve. As a direct ISO 15552 dimensional replacement, match the 155mm stroke, PT3/8 port, and your required mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2) to your existing footprint.
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 SED63X155S FAQ
Because the double-rod design has equal piston area on both sides, it delivers 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa in both the extend and retract directions.
Yes. The SED63X155S is a profile cylinder dimensionally interchangeable per ISO 15552. Just ensure your machine has rear-rod clearance, as the through-rod extends from both end covers, and select from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
