Dimensions and Specifications of 6903Z Bearing for Optimal Performance

Understanding the Dimensions of 6903Z Bearings


Bearings are essential components in various mechanical systems, acting as a support mechanism that allows for smooth and efficient movement between moving parts. Among the vast array of bearing types, the 6903Z bearing stands out due to its unique dimensions and versatile applications. In this article, we will explore the dimensions, features, and applications of the 6903Z bearing.


What is a 6903Z Bearing?


The 6903Z bearing is a type of deep groove ball bearing, one of the most commonly used bearings in the industry due to its straightforward design and efficiency. The designation “6903Z” indicates a specific size and type of bearing, where 69 signifies the series, 03 denotes the bore size, and Z refers to the inner seal that protects the inner workings of the bearing from dust and debris.


Dimensions of 6903Z Bearings


The standard dimensions of the 6903Z bearing are as follows


- Bore Diameter (d) 17 mm - Outer Diameter (D) 30 mm - Width (B) 7 mm


These dimensions provide the 6903Z bearing with a compact profile that makes it suitable for a variety of applications. The small bore and outer diameter allow for easy integration into space-constrained designs, while the width ensures stability under load.


Features of the 6903Z Bearing


1. Deep Groove Design The deep groove ball design of the 6903Z allows it to accommodate both radial and axial loads, making it a reliable choice for various mechanical applications.


2. Metal Shielding The Z in its name points to its metal shield. The shield protects the bearing from contaminants, providing longevity and reliability. This feature is especially important in environments with dust or moisture.
