A Double Row Deep Groove Ball Bearing is a type of rolling bearing with two rows of balls running in deep raceways. It’s designed to support high radial loads and moderate axial loads in both directions — offering greater load capacity than a single row deep groove bearing while maintaining a compact size.

Construction

• Two rows of precision steel balls
• Inner and outer rings with deep grooves
• Cage (typically steel, brass, or polyamide) to evenly space balls
• Shielded (ZZ) or sealed (2RS) versions are available for protection against dirt and moisture
