Double row angular contact bearings are precision components designed to handle combined radial and axial loads simultaneously. Their unique two-row ball arrangement provides higher load capacity and rigidity compared to single-row bearings, making them ideal for industrial applications like machine tools, gearboxes, and heavy machinery. These bearings typically feature a 30-40 degree contact angle for optimal force distribution and are available in various configurations (universal, tandem, back-to-back) to suit different operational requirements.
