Airtac SED Double Rod Cylinder SED50X230S
The AirTAC SED Double Rod Cylinder SED50X230S 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 230mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X230S
The AirTAC SED50X230S is a double-acting, double-rod ISO 15552 profile cylinder. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 825 N of thrust in both directions at 0.5 MPa. The extruded aluminum barrel eliminates external tie rods for a clean, integrated profile.
Fitted with the -S magnet option, it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The rear rod can mount a cam or sensor flag to trigger secondary mechanisms, while adjustable air cushions at both ends decelerate the 230 mm stroke.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 230 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 SED50X230S Is Used
Gripper Transfer Arms
Drives a 825 N both-way transfer arm in packaging lines, using the twin rods to prevent jaw rotation during vertical product lifting.
Dual-Side Labeling Heads
Powers a labeling station from both ends simultaneously, maintaining perfect parallel motion across the 230 mm stroke for precise label application.
Pallet Pusher Mechanisms
Indexes pallets with equal push and pull force, using the rear rod to actuate a diverter cam at mid-stroke.
Is the Airtac SED Double Rod Cylinder SED50X230S the Right Cylinder?
Selecting this 50 mm bore provides 825 N both ways at 0.5 MPa. If your mechanism needs less force, step down to the 40 mm bore (528 N); if pushing heavier loads, step up to the 63 mm bore (1402 N). Choose the SED over a single-rod SE when the load requires anti-rotation guidance or a rear-rod output for dual-side tooling.
At 230 mm stroke, ensure external guide rails carry heavy lateral loads to prevent rod binding. For fail-safe position holding on air loss, note that the SED piston drifts; the cushions only decelerate near stroke end and do not lock. Use a BSED double-rod rod lock or external pilot check valve instead. ISO 15552 mounting interfaces include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR).
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 SED50X230S FAQ
The SED50X230S delivers equal force in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The twin rods provide superior anti-rotation guidance and allow the rear rod to drive a secondary mechanism or sensor flag. It is dimensionally interchangeable per ISO 15552, using a PT1/4 port and M16x1.5 rod thread.
