Understanding the Dimensions and Applications of the 6308 ZZ Bearing

The 6308 ZZ bearing is a type of radial ball bearing that stands out due to its robust design and versatile applications. Often employed across various industries, from automotive to manufacturing, understanding its dimensions and specifications is crucial for optimal performance in machinery and equipment.

Dimensions of the 6308 ZZ Bearing

The '6308' designation provides vital information about the bearing's dimensions. The first digit '6' signifies that it belongs to the 6-series of bearings, commonly used in standard industrial applications. The subsequent digits indicate size; in this case, the dimensions are as follows

- Inner Diameter (ID) 40 mm - Outer Diameter (OD) 90 mm - Width (W) 23 mm

The ZZ prefix denotes that this bearing features metal shields on both sides, which protect the internal components from dust, dirt, and other contaminants while also retaining lubrication. This feature is particularly beneficial for applications subject to challenging environmental conditions.

Load Ratings and Performance

The 6308 ZZ bearing is designed to handle radial loads effectively. Its dynamic load rating (the maximum load that can be applied when the bearing is in motion) is approximately 16,000 Newtons, while the static load rating (the maximum load that can be applied when the bearing is stationary) is around 9,000 Newtons. These ratings indicate a solid performance under a variety of operating conditions, making it suitable for both light and medium-duty applications.

Material and Design

Typically, the 6308 ZZ bearing is constructed from high-quality steel, which provides strength and durability. The steel used is often treated to enhance wear resistance and longevity, especially under heavy loads or heat. Additionally, the design of the bearing allows for smooth rotation, reducing friction and increasing efficiency in machinery operations.
