Why do some customers choose ceramic ball bearings?

What kind of bearings are called ceramic ball bearings?

As the name suggests, the ball is made of ceramic. Ceramic ball bearings are categorized as full ceramic and hybrid ceramic.

In full ceramic bearings, both the rolling elements and rings are made of ceramic.

In hybrid ceramic bearings, the rolling elements are ceramic balls (such as silicon nitride or zirconium oxide), while the rings are steel or stainless steel.

So why do some customers insist on us offering ceramic ball bearings?

Ceramic ball bearings offer advantages such as high hardness, low friction, high temperature resistance, corrosion resistance, and electrical corrosion resistance, making them suitable for harsh environments and high-performance applications. Compared to steel bearings, ceramic bearings offer higher speeds, longer service life, and greater reliability, reducing maintenance costs and improving efficiency. Of course, these advantages mean that ceramic ball bearings are not cheap.

So, what common industries and equipment require ceramic ball bearings?

- Aerospace: Aircraft engines and turbochargers/superchargers; aircraft landing gear

- Automotive: High-performance vehicles; transmissions and suspension systems

- Robotics: Effectively reduces friction and improves motion precision

- Highly corrosive environments, such as various subsea projects
