6800 And 6900 Series 3x8x4 Ceramic Bearing For Bicycle Wheel Hub

Product Specification

The Brief Introduction of CSQ 6800 Series and 6900 Series of Ceramic Ball Bearings

We have three factories in China.

•In 2005, Beijing Zhongxing Shiqiang Ceramic Bearing Co., Ltd. was founded.

•In 2017, Liaoning Zhongxing Shiqiang New Material Co.,Ltd. was founded.

•In 2020, Zhongxing Shiqiang Technology (Tianjin) Co., Ltd. was founded.

The below photo is our ceramic bearings of 6800 series and 6900 series. 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 and ball, we also produces these three materials. 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 ). Other details of products, please see the below photo.

Fast and smooth riding ceramic bearings used in bicycle wheel hubs

The hub contains bearings that enable the wheel to rotate around the axle smoothly.

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

1. Reduced Friction: Ceramic bearings have a smoother surface finish and a lower coefficient of friction compared to steel bearings. This results in reduced rolling resistance and improved efficiency. With lower friction, ceramic bearings allow for more efficient power transfer from the rider's pedaling efforts to the wheels, leading to enhanced speed and performance.

2. High-Speed Capability: Ceramic bearings excel at high-speed rotations due to their reduced weight and lower friction properties. This is particularly advantageous for road cycling or high-speed racing, where maintaining speed and reducing energy loss are critical. The reduced friction in ceramic bearings allows for smoother and faster rotation, contributing to improved speed and performance.

3. Durability: Ceramic bearings generally have a longer lifespan compared to steel bearings. They are highly resistant to wear, heat, and deformation, allowing them to withstand high loads and repetitive stresses common in cycling. The durability of ceramic bearings translates into extended maintenance intervals and improved reliability, making them ideal for high-performance applications.

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.

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.
