Single and double row designs: Deep groove ball bearings can be single or double rows. The single-row design is suitable for standard loads, while the double-row design is suitable for higher loads. Track depth: The inner and outer rings of the bearing have a deeper track, which increases its radial load capacity. Ball spacing: The steel balls in the bearing are separated by a cage, which ensures that the steel balls are evenly distributed and improves the stability and efficiency of the bearing. Sealing and shielding: Depending on the application, bearings can be configured with different types of sealing or shielding caps, such as rubber seals and metal shields.
