Brief Description
Double Row Ball Bearings are designed for applications that exceed the load-carrying capacity of a single row bearing but require the flexibility and alignment features of a DGBB. By incorporating two rows of rolling elements, this design significantly increases the bearing's radial and axial load support and enhances rigidity.
Introduction
Our double row bearings offer a compact and powerful solution, providing the performance equivalent of two single row bearings mounted side-by-side, but in a narrower design. They are essential for applications facing heavy radial loads, significant bidirectional axial loads, and moments of tilt. The increased rigidity minimizes shaft deflection, ensuring higher precision and extended operational life, especially in tough industrial environments.
