Understanding 6807 Bearings Dimensions and Applications
Bearings are critical components in machinery, enabling smooth rotational or linear movement by reducing friction between moving parts. Among the various types of bearings, the 6807 bearing stands out due to its unique dimensions and versatile applications. This article delves into the specifications, dimensions, and uses of 6807 bearings, providing a comprehensive overview for engineers and enthusiasts alike.
What is a 6807 Bearing?
The 6807 bearing is part of the 68 series, which are commonly categorized as deep groove ball bearings. These bearings are designed with a deep raceway that allows for high radial loads and a degree of axial load capability, making them suitable for various applications across multiple industries, including automotive, aerospace, and industrial machinery.
Dimensions of 6807 Bearings
The dimensions of a 6807 bearing are standardized, which facilitates easy replacement and maintenance. The most common specifications for a 6807 bearing are as follows
- Inner Diameter (ID) 35 mm - Outer Diameter (OD) 47 mm - Width (W) 7 mm
These measurements contribute to the bearing's capacity and performance. Given its size, the 6807 bearing is compact yet robust, allowing it to fit into applications where space is limited while still providing substantial load-bearing capability.
Load Ratings
Understanding the load ratings of a 6807 bearing is crucial for its effective application. The dynamic load rating is approximately 12,700 N (Newtons), while the static load rating is around 6,100 N. These ratings indicate the maximum load the bearing can handle under dynamic and static conditions, respectively. It’s essential to select a bearing that meets the load requirements of specific applications to prevent premature failure.
Materials and Construction
The 6807 bearing is typically constructed from high-quality materials such as chrome steel, stainless steel, or ceramics. Chrome steel is advantageous for its strength and resistance to wear, making it a common choice for various applications. Stainless steel bearings, while slightly more expensive, offer superior resistance to corrosion, making them ideal for marine environments or applications that involve exposure to moisture.
