Airtac SED Double Rod Cylinder SED50X60
The AirTAC SED Double Rod Cylinder SED50X60 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 60mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X60
The AirTAC SED50X60 is a double-acting, double-rod ISO 15552 profile cylinder. A 20mm rod extends from both end covers, yielding exactly 825 N of thrust and 1154 N at 0.7 MPa in both directions. This symmetry is vital for tooling needing identical push and pull dynamics. The extruded aluminum barrel omits external tie rods.
This 50mm bore unit uses a PT1/4 port and features field-adjustable air cushioning at 30mm length on both ends to decelerate loads. Without the -S magnet option, this SKU has no internal position sensing. The rear rod extension can mount a secondary cam or mechanical flag to trigger external limits.
Airtac SED Double Rod Cylinder SED50X60 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED50X60 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 60 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| 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, 30 mm |
| Max stroke | Up to 1200 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SED50X60 Is Used
Shuttle Transfer
Drives a 60mm transfer shuttle for PCB handling. The 825 N equal both-way force ensures stable part pushing and return without asymmetric acceleration.
Spot Welding Head
Lowers a 50mm spot welding electrode. Twin rods prevent electrode yaw during the 60mm stroke, maintaining tip alignment for consistent weld nuggets.
Dual-Side Gripper
Actuates a centering gripper where both rods drive opposing clamps. The synchronized 1154 N output at 0.7 MPa grips heavy sheet metal blanks firmly.
Is the Airtac SED Double Rod Cylinder SED50X60 the Right Cylinder?
Choose this 50mm bore if your mechanism requires 825 N both ways at 0.5 MPa. Stepping down to the 40mm bore drops output to 528 N both ways, while the 63mm bore raises it to 1402 N. The twin-rod architecture resists torsional rotation better than a single-rod SE cylinder, guiding heavy payloads without yawing. Mounting is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR).
A plain SED does not hold position on air loss; the piston drifts. The adjustable cushion only decelerates near stroke end, acting as a brake rather than a lock. For fail-safe holding, use a BSED double-rod lock cylinder or an external pilot-operated check valve. At 60mm stroke, side loads are minimal, but always guide the load externally.
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 SED50X60 FAQ
Because the double-rod design has equal piston area on both sides, force is identical in extend and retract: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
Yes. The SED50X60 is dimensionally interchangeable per ISO 15552. Match the 50mm bore, 60mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Leave rear-rod clearance, as a rod exits both ends.
