Detailed Specifications and Dimensions of 6311 ZZ Ball Bearings for Industrial Applications

Understanding the Dimensions of 6311 ZZ Bearings


Bearings play a crucial role in various mechanical systems, allowing for smooth movement and reducing friction between moving parts. Among the myriad of bearings available, the 6311 ZZ bearing holds a significant place due to its versatile applications and robust design. This article delves into the dimensions and specifications of the 6311 ZZ bearing, highlighting its importance and common applications in industries.


What is a 6311 ZZ Bearing?


The 6311 ZZ bearing is a type of deep groove ball bearing. The designation '6311' refers to its specific dimensions, while 'ZZ' indicates that the bearing is shielded on both sides. This shielding helps protect the internal components from dust, dirt, and moisture, thereby extending the bearing's life and enhancing its performance.


Dimensions of the 6311 ZZ Bearing


To understand the suitability of the 6311 ZZ bearing for various applications, it's essential to consider its dimensions


- Outer Diameter (D) 80 mm - Inner Diameter (d) 50 mm - Width (B) 18 mm


These dimensions paint a clear picture of the bearing's size and capability. The 50 mm inner diameter allows it to fit onto shafts of corresponding sizes, while the 80 mm outer diameter and 18 mm width make it sufficiently robust to handle substantial loads.


Load Ratings

In addition to its physical dimensions, the load ratings of the 6311 ZZ bearing are paramount in determining its effectiveness in various roles. The dynamic load rating is typically around 80 kN, whereas the static load rating is approximately 50 kN. These values suggest that the bearing can efficiently handle both radial and axial loads, making it suitable for high-speed applications.
