Collection: Double Row Self-Aligning Ball Bearings

Double row self-aligning ball bearings feature two rows of balls running on a spherical outer ring raceway, allowing the bearing to accommodate angular misalignment of the shaft relative to the housing. This self-aligning capability makes them ideal for applications where shaft deflection or mounting errors are expected, while still supporting moderate radial loads and limited axial loads in both directions at moderate speeds.

When selecting double row self-aligning ball bearings, consider the bore diameter, load capacity requirements, and operating speed. These bearings are commonly used in agricultural machinery, conveyor systems, wood-working equipment, and textile machinery where shaft misalignment due to deflection or thermal expansion must be accommodated. The designation system typically indicates bore size, diameter series, and width series to help match the bearing to your application requirements.
