The 3309-BD-XL Double-row angular contact ball bearings primarily consist of an integral inner ring (or double-half inner ring), an integral outer ring, two rows of balls, and a cage. The contact angle is typically 25°, 30°, or 35°, with the two rows of balls arranged back-to-back, providing bidirectional axial load capacity.

A single bearing can withstand both radial and bidirectional axial loads, eliminating the need for paired installation. They offer high axial rigidity and excellent resistance to overturning moments, making them suitable for handling instantaneous overloads. The integral design simplifies installation, saves space, and is widely used in applications requiring compact designs.
