Understanding the 625 ZZ Ball Bearing Features, Applications, and Benefits

The 625 ZZ ball bearing is a quintessential component widely used in various industrial applications and consumer products. Known for its small size and high performance, this bearing type has gained popularity due to its robustness and versatility. In this article, we will explore the features, applications, and benefits of the 625 ZZ ball bearing.

What is a 625 ZZ Ball Bearing?

The designation 625 ZZ refers to a specific dimension and design of a deep groove ball bearing. The 625 denotes the bearing's series size, which indicates its internal diameter, outer diameter, and width. Specifically, the 625 ZZ ball bearing has an inner diameter of 5mm, an outer diameter of 16mm, and a width of 5mm. The ZZ suffix indicates that this bearing comes with metal shields on both sides, which helps in protecting the lubricant within the bearing from impurities while also minimizing lubricant leakage.
