Dimensions and Specifications of 6303 ZZ Bearing for Precision Applications

Understanding the 6303 ZZ Bearing Dimensions and Applications


Bearings play a crucial role in various mechanical systems, allowing for smooth rotation and movement. Among the extensive range of bearings available, the 6303 ZZ bearing stands out due to its robust design and versatile applications. This article will explore the dimensions, specifications, and practical uses of the 6303 ZZ bearing.


What is a 6303 ZZ Bearing?


The 6303 ZZ bearing is a type of deep groove ball bearing, which is one of the most commonly used bearing types in the industry. The '6303' classification signifies certain dimensions and load-carrying capacities, while the 'ZZ' designation indicates that the bearing comes with metal shields on both sides. These shields serve to protect the internal components from dust, debris, and other contaminants, thus extending the lifespan of the bearing.


Dimensions and Specifications


The typical dimensions of a 6303 ZZ bearing are as follows


- Inner Diameter (ID) 17 mm - Outer Diameter (OD) 47 mm - Width (W) 14 mm - Dynamic Load Rating (C) Approximately 10.5 kN - Static Load Rating (C0) Approximately 5.4 kN - Speed Rating The 6303 ZZ bearing can typically operate at speeds up to 18,000 RPM, depending on the specific lubricant and operating conditions.


These dimensions make the 6303 ZZ bearing suitable for various applications, ranging from household appliances to industrial machinery.


Material Composition


Typically, the inner and outer rings of a 6303 ZZ bearing are made from high-quality carbon steel, which provides excellent durability and strength. The balls inside are also made of carbon steel, although ceramic alternatives may be used for specialized applications where lower friction or higher temperatures are concerns. Furthermore, the ZZ shield is often constructed from steel, ensuring robust protection against environmental factors.
