Dimensions and Specifications for 6905Z Bearing and Similar Models

Understanding the Dimensions of the 6905Z Bearing A Comprehensive Guide


Bearings are essential components in various mechanical applications, serving as supports that reduce friction between moving parts. Among different types of bearings, the 6905Z series has gained popularity due to its versatility and robust performance. This article will delve into the dimensions and characteristics of the 6905Z bearing, highlighting its applications and importance in machinery.


What is the 6905Z Bearing?


The 6905Z bearing is a type of deep groove ball bearing that features a metal shield on one side, identifiable by the Z in its designation. This shield is designed to protect against contaminants and retain lubrication in the bearing, thereby extending its lifespan and enhancing performance. These bearings are typically manufactured from high-quality materials such as chrome steel, ensuring durability and reliability.


Dimensions of the 6905Z Bearing


The standard dimensions of a 6905Z bearing are crucial for its compatibility with various applications. The main dimensions include


- Inner Diameter (d) 25 mm - Outer Diameter (D) 42 mm - Width (B) 9 mm


These dimensions are essential for selecting the right bearing for specific machinery. The inner diameter determines the shaft size that the bearing can accommodate, while the outer diameter and width are important for fitting into housings and ensuring stability during operation.


Load Ratings and Performance

The load ratings of the 6905Z bearing indicate its capacity to handle radial and axial loads. The dynamic load rating (C) for a 6905Z bearing is approximately 6,100 N, while the static load rating (C0) is about 3,600 N. These figures signify that the bearing can endure significant loads, making it suitable for high-performance applications.
