Product Detail

Shanghai Metal Corporation is a leading Hybrid Ceramic Bearing manufacturer and supplier.

Hybrid ceramic bearings combine ceramic balls with metal inner and outer rings, offering high-speed performance, heat resistance, low friction, corrosion resistance, and electrical insulation. The low density and high hardness of the ceramic balls make them ideal for high-speed rotation and high-temperature environments, while also reducing lubrication needs. Due to excellent electrical insulation properties, these bearings are widely used in motors, generators, aerospace, automotive industries, and other demanding fields, particularly in corrosive, high-humidity, or high-temperature conditions.

1. Application Fields Hybrid ceramic bearings are widely used in demanding industries such as motors, generators, aerospace, automotive industries, and precision machinery. In applications requiring high speed, precision, and durability, hybrid ceramic bearings offer a longer service life and more stable performance compared to conventional bearings.

2. Environmental Requirements: These bearings are particularly suited for high-temperature, humid, or corrosive environments, where traditional steel bearings may suffer from performance degradation due to heat or chemical exposure. The ceramic balls also provide excellent electrical insulation, preventing current from passing through the bearing and causing electrical erosion, making them especially useful in electrical equipment.

3. Service Life: Extremely long service life (compared to traditional metal bearings).
