Miniature 695 / 623 Ceramic Ball Bearings For Autonomous Underwater Vehicle

Product Specification

The Brief Introduction of CSQ Ceramic Ball Bearings

The below photo is our miniature ceramic bearings of 693 and 695. Our factory produces three materials, they are silicon nitride, silicon carbide and zieconia, you can choose one of them you want. And about the ring, we recommend you the ceramic inner ring and outer ring. About the ball, you can also choose zirconia, silicon nitride and silicon carbide. For the cage, we have PTFE, Nylon and PEEK, but you can also choose other materials. The precision grade of bearings is high up to P4 ( ABEC7 ). About sealing, you can choose sealed or open. If you choose sealing, we have PEEK, PTFE, Rubber or others you want. Other details of products, please see the below photo. If you want to know more, welcome email me~

Corrosion Resistance and Temperature Stability for AUV

Miniature ceramic bearings can be used in various parts of Autonomous Underwater Vehicles, such as pressing housings, sensors and transducers, electrical connectors, heat exchangers and other parts.

And if you use our miniature ceramic ball bearings, you will get :

1. Corrosion resistance: AUVs operate in highly corrosive marine environments with exposure to saltwater. Ceramic bearings have excellent corrosion resistance, making them ideal for use in AUVs. They can withstand prolonged exposure to saltwater without deteriorating or rusting, ensuring the longevity and reliability of the bearings, that means less maintenance and long service life.

2. High hardness and wear resistance: Ceramic materials, such as silicon nitride or zirconia, used in ceramic bearings exhibit high hardness and exceptional wear resistance. This property is particularly beneficial in AUV applications where the bearings are subjected to high loads and rotational speeds. Ceramic bearings can withstand these demanding conditions without significant wear, resulting in extended bearing life and reduced maintenance requirements.

3. Low friction and high efficiency: Ceramic bearings have lower friction coefficients compared to metal bearings. This characteristic reduces energy losses due to friction, resulting in improved overall efficiency of AUV propulsion systems. The reduced friction also enables smoother operation and reduces heat generation, contributing to enhanced performance and thermal management in AUVs.

4. Reduced noise and vibration: Ceramic bearings exhibit lower levels of noise and vibration compared to metal bearings. This characteristic is desirable in AUVs as it helps minimize acoustic signatures and disturbances, allowing for quieter and less disruptive underwater operations.

CSQ that Contains Industry and Trade

Our company is specialized in producing ceramic balls and ceramic bearings, the technology is inherited from the parent company: Beijing Zhongxing Shiqiang Ceramic Bearing Company, which already has FDA,REACH,ROHS,ISO9001,ISO14001,ISO45001 certifications.

Now I will introduce the Tianjin branch, the factory covers an area of about 4000 square meters, equipped with automatic production and assembly line, ball grinding machine and other production equipment, as well as a variety of bearing testing equipment. We have professional testing equipment and technicians. All products are 100% strictly inspected before exporting, including appearance defect inspection, roundness, roughness and geometry size, and all products meet ISO international standards.

At present, our company mainly produces ceramic ball bearings, sliding bearings, ceramic balls and ceramic industrial parts. The production materials are high performance ceramic materials, mainly SSIC, Si3N4 and ZrO2 material. And we have a series of professional production and inspection equipments, such as the HIP (High temperature Insostatic Pressing) Equipment is from ABB Sweden, the inspection equipments are mostly from Mitutoty. The products will be strictly 100% inspected before export.

Our main customers are mainly located in Germany, United Kingdom and other European countries and Japan, Korea and other Asian countries. We dedicate to provide high level products and technical services, our experienced and professional team is committed to handling your enquiry quickly and accurately.
