HZK Double-row deep groove ball bearings are rolling bearings with a deep-groove raceway design. Standard models include 4200A and 4300A. While having the same outer and inner diameters as single-row deep groove ball bearings, they feature a greater axial width and significantly higher radial load capacity than single-row models, making them suitable for configurations where the load capacity of single-row bearings is insufficient.
Deep groove ball bearings have a particularly wide range of applications. Consequently, they are available in a wide variety of types and sizes. The HZK standard series includes the following types: ,Single-row deep groove ball bearings , Single-row deep groove ball bearings with filler grooves , Stainless steel deep groove ball bearings ,Double-row deep groove ball bearings – Ceramic deep groove ball bearings , Deep groove ball bearings for high-temperature applications.
