Airtac SED Double Rod Cylinder SED63X750
The AirTAC Airtac SED Double Rod Cylinder SED63X750 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 750mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X750
The AirTAC SED63X750 is a double-acting, double-rod ISO 15552 profile cylinder built for demanding 750 mm stroke applications. Because a rod exits both end covers, the effective piston area is identical in both directions. This means the cylinder generates an equal 1402 N of thrust and pull at 0.5 MPa, eliminating the force differential found in single-rod units.
This SKU lacks the -S magnet option, so it has no onboard position sensing. The extruded aluminum barrel incorporates adjustable air cushioning at both ends (36 mm cushion length) to decelerate the load near stroke extremes. You must leave rear-rod clearance, as the twin-rod design increases overall length compared to a standard SE cylinder.

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 SED63X750 Is Used
Long-Stroke Transfer Conveyors
Drives heavy pallets over 750 mm with equal 1402 N push/pull force at 0.5 MPa, using the twin rods to keep loads aligned without skewing.
Multi-Stage Machining Centers
Indexes tooling carriages precisely; the rear rod can mount a physical cam or limit flag to trigger mechanical stops, independent of sensors.
Automated Assembly Presses
Applies 1962 N of equal force in both directions at 0.7 MPa for pressing and returning subassemblies, ensuring consistent cycle dynamics.
Is the Airtac SED Double Rod Cylinder SED63X750 the Right Cylinder?
Selecting this 63 mm bore provides 1402 N of equal both-way force at 0.5 MPa. If your application requires less output, the adjacent 50 mm bore yields 825 N both ways. For heavier demands, stepping up to the 80 mm bore provides 2268 N. The twin-rod design is highly recommended for 750 mm strokes because the second rod adds dual-side guidance, resisting rotation and side-loading far better than a single-rod SE cylinder.
Because this is a 750 mm stroke, external guide rails are strongly advised to prevent sag and protect the 20 mm rod from bending moments. Note that a plain SED does not hold position on air loss; the piston will drift. For fail-safe holding, use a BSED double-rod rod lock or an external pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552 with a PT3/8 port and M16x1.5 rod thread.
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 SED63X750 FAQ
The SED63X750 provides equal force in both directions due to the double-rod design. It delivers 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
The twin-rod design provides dual-side guidance and superior anti-rotation resistance, which is critical for a 750 mm stroke. It also allows the rear rod end to drive a secondary mechanism or cam. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
