This page explains how Magnetic Coupling is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A non-contact torque transmission device that uses magnetic fields to transfer motion through a barrier.
Technical details and manufacturing context for Magnetic Coupling
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Torque | 10–500 N·m | Select based on driven load and speed. |
| Maximum Speed | 3000–6000 rpm | Limited by centrifugal stress and bearing life. |
| Operating Temperature | -40–85 °C | Above 85°C may demagnetize permanent magnets. |
| Torque Transmission Efficiency | 95–98 % | Higher efficiency reduces energy loss. |
| Shaft Diameter Range | 20–120 mm | Must match driven and driving shafts. |
| Air Gap | 2–8 mm | Larger gap reduces torque capacity. |
| Magnet Material | NdFeB | High energy product, temperature limited. |
| Housing Material | SS304/316 | Corrosion resistance for harsh environments. |
| Weight | 5–50 kg | Affects installation and support structure. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 100 bar (standard), higher with reinforced barriers |
| speed range: | 0 to 10,000 RPM (limited by bearing system) |
| temperature: | -40°C to 150°C (standard), up to 300°C with special materials |
| gap tolerance: | 1-10 mm air gap depending on torque requirements |
| torque capacity: | 0.1 Nm to 5000 Nm depending on size and magnet type |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
Quoted from the published standard.
2 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It transmits float movement from the liquid side to the indicator side without physical penetration, maintaining a hermetic seal while allowing accurate level measurement.
The coupling uses neodymium magnets, a stainless steel housing, and PTFE seals.
The rated torque range is 10–500 N·m, maximum speed is 3000–6000 rpm, operating temperature is -40–85°C, and operating pressure is 1.0–1.6 MPa. These are reference ranges; confirm for your specific model.
Check the rated torque, speed, temperature, pressure, shaft diameter, air gap, and ingress protection against your requirements. Always confirm model-specific values and standards with the legal manufacturer or supplier.
