Airtac SED Double Rod Cylinder SED63X75S
The AirTAC Airtac SED Double Rod Cylinder SED63X75S 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 75mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X75S
The AirTAC SED63X75S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 20 mm rod exits both ends, the annular piston area is identical on extend and retract, yielding 1402 N of force each way at 0.5 MPa. The integrated -S magnet pairs directly with CMSE reed or DMSE electronic sensors in the barrel groove.
This unit features a PT3/8 port and an M16x1.5 rod-end thread. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the rear rod provides excellent anti-rotation guidance for tooling.

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 SED63X75S Is Used
Web Guiding Mechanism
Drives a steering roller with 1402 N both ways at 0.5 MPa, using the rear rod to mount a cam for edge-trace feedback.
Dual-Side Press Fixture
Clamps a workpiece from opposite ends simultaneously, leveraging the equal extend and retract forces to prevent deflection.
Component Transfer Unit
Shifts parts between machining stations, relying on the twin 20 mm rods to prevent binding under dynamic loading.
Is the Airtac SED Double Rod Cylinder SED63X75S the Right Cylinder?
Choose the SED63X75S when your mechanism requires 1402 N of both-way thrust at 0.5 MPa. If your application needs less force, step down to the 50 mm bore (825 N both ways); if you need more, step up to the 80 mm bore (2268 N both ways). The twin-rod design is preferred over a single-rod SE when you need to mount a rear cam or sensor flag, or when the load requires high resistance to torsional rotation. Remember that a standard SED does not hold position on air loss—the piston drifts. For fail-safe holding, use a BSED double-rod lock cylinder or an external pilot-operated check valve. To replace an existing ISO 15552 cylinder, match the 63 mm bore, 75 mm stroke, PT3/8 port, and your required mounting (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 SED63X75S FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
Yes. The SED63X75S is a true ISO 15552 profile cylinder. Just match the 75 mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that the rear rod requires clearance.
