Koyo Ceramic Hybrid Ball Bearing

Koyo 3NC Ceramic Hybrid Ball Bearings are high-performance bearings that combine ceramic balls with steel inner and outer rings. They are designed to meet the demands of applications that require high speeds, high temperatures, or electric insulation. Here are some of the advantages of Koyo 3NC Ceramic Hybrid Ball Bearings:

Electric Insulation: These bearings eliminate electric arcing or fluting by insulating the bearing, which is crucial for electric motor applications.
High-Speed Performance: The ceramic balls are 60% lighter than steel balls, allowing the bearings to operate at speeds up to 50% higher than traditional steel ball bearings.
Temperature Resistance: They have a lower temperature rise at high speeds and are capable of handling high temperature environments.
Increased Rigidity: The ceramic balls offer greater rigidity, enhancing the bearing’s overall performance.
Longer Service Life: The use of ceramic balls improves grease life and extends the bearing’s service life.
Cost Savings: These bearings can reduce downtime and maintenance costs associated with traditional steel ball bearing failure.
Interchangeability: They are dimensionally interchangeable with current electric motor bearings, requiring no special modifications for installation1.
The 3NC series includes a variety of model numbers within the 6200 and 6300 series, all of which are double shielded and filled with Exxon Polyrex® EM grease. These bearings are ideally suited for a wide range of extreme applications, such as power generation, electric motor industry, turbochargers, and high-speed industrial machinery1.
