Inner and Outer Rings: The 6807 thin section bearing consists of inner and outer rings, which are the primary bearing rings. These rings are typically made from chrome steel material (material can be chosen based on requirements) and undergo precise machining and heat treatment to ensure their hardness and durability.
Steel Balls: The steel balls within the bearing are also usually made from chrome steel material (material can be chosen based on requirements). These balls are evenly distributed between the inner and outer rings, reducing friction through rolling motion and supporting axial and radial loads.
Cage: The cage is the component that supports the steel balls. It is usually made from plastic or metal and maintains the even distribution of the balls while minimizing collisions and friction between them.
Seals: Some 6807 thin section bearings may come equipped with seals to prevent dust, dirt, and other external objects from entering the bearing interior. This helps protect the lubricating grease and extends the bearing's lifespan.
The sealing covers for the 6807 bearing mainly come in three types: ZZ, 2RS, and OPEN.
The 6807 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 6807 OPEN type bearing is more suitable for applications in clean environments or where regular cleaning is required.
6807 ZZ refers to the 6807 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.
6807 2RS refers to the 6807 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.
In some components of automobiles, such as transmissions and generators, the 6807 bearing is also utilized.
The 6807 bearing is a crucial bearing model used in most electric bicycle motor. This bearing has dimensions of 35mm inner diameter, 47mm outer diameter, and 7mm thickness. Its size design allows it to maintain low friction and high efficiency during high-speed rotation.
The 6807 bearing is a key component widely used in various industries. From the automotive industry to electric bicycle sector, this bearing plays an indispensable role in many critical devices. Its high-speed operation, durability, and reliability make it the preferred choice in these industries.
