Hybrid Ceramic Bearings

ISK BEARINGS ceramic bearings, made of materials like ZrO2 and Si3N4, boast excellent hardness, high temperature resistance, and corrosion resistance. Hybrid ceramic bearings combine ceramic balls with chromium steel or stainless steel inner and outer rings, balancing the favorable characteristics of ceramics with the durability of steel. They are suitable for high-speed, high-temperature, and corrosive environments, providing better operational performance and durability for industrial equipment, minimizing downtime, and reducing potential losses for companies.

By choosing stainless steel for the inner and outer rings based on the application environment, the adaptability can be extended to a wider range of conditions, such as resistance to acids, alkalis, corrosion in seawater, dilute nitric acid, marine climates, steam, and other corrosive media.

GCr15 Hybrid Ceramic Bearings

GCr15 is a type of high-carbon chromium bearing steel commonly used in traditional steel bearings. In hybrid ceramic bearings, GCr15 is often used for the inner and outer rings, paired with ceramic balls.
This combination maintains the advantages of ceramic balls (such as reducing weight and increasing hardness) while still utilizing the strength and durability of steel to provide better performance.

SS Hybrid Ceramic Bearings

Stainless steel bearings have inner and outer rings that are less prone to rust compared to bearing steel. In hybrid ceramic bearings, stainless steel is used for the inner and outer rings, while ceramic balls are employed.
This combination provides resistance to corrosion and moisture for applications that require it.

Precautions for Operating with Hybrid Ceramic Bearings

It is still recommended to use lubricating grease. Failure to do so may affect the bearing's lifespan.
Must be used in strong acid, strong alkali, and other chemical environments. Please contact ISK BEARINGS.
