Understanding the Dimensions of 6302 ZZ Bearings


Bearings are essential components in machinery and equipment, providing support and reducing friction between moving parts. Among the various types of bearings, the 6302 ZZ bearing is a popular choice due to its robust design and versatile application. This article will delve into the dimensions and characteristics of the 6302 ZZ bearing, highlighting its importance in various mechanical setups.


What is a 6302 ZZ Bearing?


The designation 6302 ZZ refers to a specific type of deep groove ball bearing. The first part of the name, 6302, indicates the bearing series and its size, while ZZ denotes the presence of shields on both sides of the bearing. These shields help to retain lubrication and protect the internal components from dust, dirt, and other contaminants, thereby extending the bearing's lifespan.


Key Dimensions


The 6302 ZZ bearings have standardized dimensions that facilitate their interchangeability and usability across various applications. Here are the key dimensions of the 6302 ZZ bearing


- Inner Diameter (ID) 15 mm - Outer Diameter (OD) 42 mm - Width (W) 13 mm


These dimensions make the 6302 ZZ bearing suitable for a broad range of applications, including electric motors, automotive components, and industrial machinery.


Load Ratings


Apart from the physical dimensions, understanding load ratings is crucial when selecting a bearing. The dynamic load rating for the 6302 ZZ bearing typically stands at around 7,300 N, while the static load rating is approximately 3,700 N. These load ratings dictate the bearing's capacity to support weights and withstand operational stresses, making it vital to choose a bearing that matches the application requirements.
