Specifications and Features of 6303 Bearing for Various Applications and Industries

Understanding the Specifications of the 6303 Bearing


Bearings are essential components in various mechanical systems, providing support and facilitating movement between rotary and linear components. Among the different varieties of bearings available in the market, the 6303 bearing is a widely used deep groove ball bearing. In this article, we'll delve into the specifications and characteristics of the 6303 bearing, highlighting its applications and significance in various industries.


What is a 6303 Bearing?


The designation 6303 refers to a specific size and type of deep groove ball bearing. The system of classification consists of numbers that indicate various dimensions and features of the bearing. The 63 denotes that it belongs to the deep groove series, while the 03 indicates the specific size within that series.


Key Specifications


1. Dimensions - Inner Diameter (ID) 17 mm - Outer Diameter (OD) 47 mm - Width (B) 14 mm


These dimensions are standardized, enabling interoperability between components from different manufacturers.


2. Load Ratings - Dynamic Load Rating (C) Approximately 12,800 N - Static Load Rating (C0) Approximately 6,900 N


These ratings indicate the maximum loads that the bearing can withstand while operating (dynamic) and when at rest (static). Designers and engineers must consider these ratings to ensure the bearing functions efficiently under specific operational conditions.
