Product Description

PRODUCT DETAILS

 

The 698 bearing is a type of miniature deep groove ball bearing with an inner diameter of 8mm, an outer diameter of 19mm, and a thickness of 6mm. Its structural design is compact and is specifically tailored for scenarios with limited space. The rolling elements and rings are usually made of high-quality chrome steel, which is hard and highly wear-resistant, enabling it to effectively bear radial loads and maintain stable operation at high speeds. It has excellent high-speed performance, with a maximum rotational speed of up to 36,000 rpm. It also has a low friction coefficient during operation, significantly reducing energy loss, and has a relatively low noise and vibration level. 
In numerous industries and fields, the 698 bearing is widely used. In the medical equipment sector, it can be used in precision devices such as lung support devices, ensuring the stable operation of the equipment and guaranteeing the accuracy and safety of medical processes. In the instrumentation field, devices like clocks and flow meters have strict precision requirements, and the 698 bearing can meet these needs, helping the instruments achieve precise measurement and display. In electronic equipment, such as small motors and hard disk drives, this bearing's excellent high-speed performance and low friction characteristics enable smooth and efficient operation of the equipment. In the roller skating shoe field, the 698 bearing is suitable for the wheel axles of roller skates due to its small size, and its high-speed performance meets the speed requirements during skating. Its wear-resistant properties can handle different road surface friction, providing a smooth skating experience for roller skating enthusiasts. Additionally, in some scenarios with extremely high space requirements, such as micro machinery and model manufacturing, the 698 bearing is also an ideal choice, providing reliable support for the miniaturization and precision operation of equipment.
