Comprehensive Guide to Dimensions and Specifications of 628ZZ Bearings for Various Applications

Understanding the 628ZZ Bearing Dimensions


Bearings are vital components in machinery, allowing for smooth rotational or linear movement by reducing friction between moving parts. Among the various types of bearings available in the market, the 628ZZ bearing is well-known for its efficiency and versatility in various applications. In this article, we will explore the dimensions, characteristics, and applications of the 628ZZ bearing.


What is a 628ZZ Bearing?


The 628ZZ bearing is a miniature ball bearing that comes with metal shields on both sides, which is why it is commonly denoted with ZZ. The 6 in its designation refers to the series that this bearing belongs to, and 28 indicates its inner diameter of 8mm, outer diameter of 24mm, and the width of 8mm. This compact size makes the 628ZZ bearing suitable for applications where space is limited, yet high performance is required.


Dimensions of the 628ZZ Bearing


To define the dimensions more clearly - Inner Diameter (d) 8 mm - Outer Diameter (D) 24 mm - Width (B) 8 mm


This compact configuration allows the 628ZZ bearing to function effectively in various applications, making it popular in models ranging from toys to industrial equipment.
