The 6806 bearing is typically composed of an inner ring, an outer ring, ball bearings, and a cage (also known as a retainer). The groove on the raceway is slightly larger than the radius of the steel balls. As the balls and raceway make point contact, the bearing can withstand both bi-directional axial loads and radial loads. It is commonly used in pairs under normal circumstances to reduce the internal axial forces caused by the load and to handle radial loads.
The sealing covers for the 6806 bearing mainly come in three types: ZZ, 2RS, and OPEN.
The 6806 OPEN type bearing cover is a design without a cover, allowing the internal components of the bearing to be exposed to the external environment. This design makes the bearing more susceptible to contamination from dirt, dust, and other external particles. Therefore, the 6806 OPEN type bearing is more suitable for applications in clean environments or where regular cleaning is required.
6806 ZZ refers to the 6806 bearing with metal shields as the outer cover. The metal shields effectively block dust, contaminants, and other external particles from entering while retaining the lubricant within the bearing.
6806 2RS refers to the 6806 bearing with rubber seals as the outer cover. The rubber seals provide enhanced protection by effectively blocking moisture, dust, and other contaminants from entering. This sealing method is commonly used in harsh environments and applications that require stricter protection.
When choosing the appropriate bearing outer cover mode for your needs, consider the following factors
Application environment: Determine the potential sources of contamination and other external particles in your application environment. Based on the environmental conditions, choose between open type, metal shields, or rubber seals to provide the appropriate protection.
Precision and speed requirements: Consider the precision and speed requirements of your application. Open type bearings are typically suitable for low precision and lower speed applications, while metal shields and rubber seals offer higher protection and are suitable for medium and high precision requirements.
Maintenance requirements: Consider your maintenance needs for the bearings. Open type bearings require regular cleaning and lubrication, while metal shields and rubber seals can reduce maintenance requirements.
They are widely used in components such as transmissions and generators, providing smooth operation and durability, ensuring the reliability and performance of automobiles.
The 6806 bearing is also used in the rotating components of wind turbines, hydroelectric generators, and other energy facilities.
The 6806 bearing is a thin section bearing widely used in the bottom bracket, and hub of electric bicycles. This type of bearing has an inner diameter of 30mm, an outer diameter of 42mm, and a thickness of 7mm, making it suitable for bearing the loads generated by electric bicycles during operation. Its design features low friction and minimal noise, especially during high-speed operation.
The 6806 bearing is a key component widely used in multiple industries. From the automotive industry and energy equipment to the electric bicycle sector, this bearing plays an essential role in many critical devices. Its high-speed operation, durability, and reliability make it the preferred choice in these industries.
