Airtac SED Double Rod Cylinder SED63X170S
The AirTAC SED Double Rod Cylinder SED63X170S 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 170mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X170S
The AirTAC SED63X170S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod extends from both end covers, the annulus area is identical on both sides. This means you get exactly 1402 N of output force at 0.5 MPa in both extend and retract directions. The extruded aluminum barrel contains no external tie rods.
This specific configuration includes the -S magnet option, enabling position detection with CMSE reed or DMSE electronic sensors. The rear rod extension can simultaneously drive a secondary mechanism or mount a cam, while providing superior anti-rotation guidance compared to a single-rod SE cylinder.
Airtac SED Double Rod Cylinder SED63X170S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 170 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 SED63X170S Is Used
PCB Edge Guiding
Uses the 1402 N both-way force to center and straighten delicate printed circuit boards on a conveyor without rotational drift.
Dual-Side Labeling
Drives opposing label applicators simultaneously from a single piston, ensuring perfectly synchronized contact on both package sides.
CNC Tool Presetter
Mounts a measurement flag on the rear rod to trigger DMSE electronic sensors for precise tool height calibration.
Is the Airtac SED Double Rod Cylinder SED63X170S the Right Cylinder?
Select this 63mm bore if your application requires balanced 1402 N force both ways. If you need less power, step down to the 50mm bore providing 825 N; if you need more, step up to the 80mm bore delivering 2268 N at 0.5 MPa. The double-rod design is optimal for synchronizing two loads or preventing rotation without external guides.
To replace an existing ISO 15552 cylinder, match the 170mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED does not hold position upon air loss; for fail-safe holding, consider a BSED rod-lock variant. At 170mm stroke, the 20mm rod handles standard side loads, but always support heavy lateral loads to prevent binding.
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 SED63X170S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
The twin rods prevent load rotation better than a single-rod cylinder, allow you to mount a sensor flag or cam on the rear rod, and provide identical extend and retract speeds. Remember to leave rear-rod clearance in your machine design.
