Hybrid Ceramic Bearings

Hybrid Ceramic Deep Groove Ball Bearings
Standard hybrid ceramic bearings are single row ball bearings available from .0937" through .875" bore sizes.
Hybrid Ceramic Flanged Bearings
Flanged hybrid ceramic bearings have a solid steel flange on the outer ring. This allows the bearing to be more easily located in a housing.
Hybrid Ceramic Cylindrical Roller Bearings
Separable bearings, suitable for high speeds, can accommodate heavy radial loads and axial displacement. Commonly used in electric motors and in applications running under severe operating conditions.

Ceramic Balls

Ceramic Balls
LILY Bearing provide a wide range of ceramic ball options across a variety of sizes. Material options include Silicon nitride (Si3N4), Zirconia (ZRO2), Alumina (Al2O3) and Silicon carbide (SIC) from 0.4mm to just over 115mm in diameter with the most common sizes in between.

What Is Ceramic Ball Bearing?

Ceramic ball bearings use ceramic balls instead of steel, making them lighter, harder, and more durable. They're great for high-speed and harsh environments like aerospace and medical applications. Ceramic ball bearings are high-performance components used in harsh environments where traditional steel bearings may fail. They can spin faster than steel balls without generating as much heat, making them ideal for high-speed machinery and electric motors. The lightweight and non-magnetic properties of ceramic ball bearings also make them ideal for aerospace applications. Overall, they provide superior performance compared to traditional steel bearings in many different applications.


Ceramic Hybrid & Full Ceramic

Ceramic hybrid ball bearings feature steel races and ceramic balls, while full ceramic ball bearings are made entirely of ceramic material. Both types of bearings offer excellent durability, low friction, and high performance in harsh environments.

However, full ceramic ball bearings are more resistant to corrosion and have a higher temperature tolerance than hybrid ceramic bearings. They are for medium load and medium speed applications. It is not possible to achieve the inner and outer ring roundness that is found with precision steel bearings so full ceramic bearings have lower speed ratings. On the other hand, hybrid ceramic bearings can handle higher loads due to their steel race construction. The choice between the two depends on the specific needs of each application.


Notable Features of Ceramic Ball Bearings

Ceramic ball bearings offer benefits such as preventing electrical arcing, reducing wear and operating temperatures, extending service life and grease life. They are durable, resistant to wear, and have cooler running temperatures than steel bearings. They are a great choice for improving equipment performance and minimizing maintenance costs over time.


Different Materials for Ceramic Ball Bearings

◆Zirconia Ceramic Bearings are durable and corrosion-resistant for high-temperature industrial applications.

◆Silicon Nitride Ceramic Bearings are lightweight, strong, and wear-resistant with excellent corrosion resistance.

◆Silicon Carbide Ceramic Bearings have exceptional wear and thermal shock resistance for high-stress environments in various industries.
