Скачать или смотреть 6319M/C3VL0241 insulated bearing with dense coating structure,electrical insulation properties.

Take 6319M/C3VL0241 electrically insulated bearing as an instance.
It has an bore diameter of 95mm, an outer diameter of 200mm, and a thickness of 45mm.The outer ring is equipped with an insulating coating that is 200 microns thick and can withstand a breakdown voltage of 3000VDC.

Advantages
Effective Electrical Isolation: Can prevent electric current from passing through the bearing, avoiding electric corrosion damage to the bearing, protecting the integrity of motor bearings, and prolonging their service life.
High Interchangeability: Have the same dimensions and basic technical characteristics as non-insulated bearings, enabling 100% interchangeability and easy replacement, reducing maintenance costs.
Good Stability: With excellent high-temperature resistance, corrosion resistance, high load-carrying capacity, and long service life, they can adapt to harsh working environments.
Noise and Vibration Reduction: Through optimized design and precision manufacturing, they can significantly reduce noise and vibration during high-speed operation, improving the stability and comfort of equipment operation.

Application Scenarios

In Motors: They are used to isolate and protect against shaft currents in motors, reduce noise and vibration, and are suitable for motors in various environments, especially in medical equipment and precision instruments that require low noise.
In Reducers: They help improve transmission efficiency, protect transmission components from damage, and reduce noise and vibration in reducers.
In Gearboxes: They contribute to enhancing the operational stability of gearboxes, protecting gears and bearings from current damage and mechanical wear, and can meet the requirements of high-speed operation.

Common Types

Electrically Insulated Deep Groove Ball Bearings: Widely used, suitable for applications with general load and speed requirements, with good electrical insulation and sealing performance.
