Airtac SED Double Rod Cylinder SED63X70S
The AirTAC SED Double Rod Cylinder SED63X70S 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 70mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X70S
The AirTAC SED63X70S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 1402 N of force each way at 0.5 MPa. The extruded aluminum barrel eliminates external tie rods for a clean profile.
This 63mm bore, 70mm stroke unit includes a standard magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. The rear rod extension is ideal for mounting a cam or limit flag to trigger external mechanisms without interfering with the primary work tool.

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 SED63X70S Is Used
PCB Depanelling Press
Drives a cutting blade with 1402 N of equal force both ways, while the rear rod carries a cam to actuate the dust extraction hood.
Pallet Transfer Diverter
Uses the twin rods to resist side loads when pushing heavy pallets, preventing torsional binding during high-speed 30-800 mm/s strokes.
Gripper Synchronization Arm
Simultaneously actuates opposing grippers from one piston, relying on identical extend and retract speeds for precise part centering.
Is the Airtac SED Double Rod Cylinder SED63X70S the Right Cylinder?
Choose this 63mm bore when you need equal 1402 N force in both directions, plus anti-rotation guidance from twin rods. If your load is lighter, step down to the 50mm bore for 825 N; if you need more push, step up to the 80mm bore for 2268 N. At 0.7 MPa, this unit outputs 1962 N both ways.
For a direct ISO 15552 replacement, match the 63mm bore, 70mm stroke, PT3/8 port, and your mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED drifts on air loss; use a BSED or external 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 SED63X70S FAQ
The SED63X70S provides equal force in both directions due to its double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
A double-rod cylinder provides equal force and speed on extend and retract. The rear rod protrusion allows mounting a sensor flag or driving a secondary mechanism, and the twin rods offer superior resistance to rotational torque compared to a single rod.
