Double Row Angular Contact Thrust Ball Bearings

This category includes special double-row angular contact thrust ball bearings, with main models such as 350769, 351793, BD1-8000, and BD1B 351890 A. Unlike standard thrust ball bearings, these models are specifically designed for heavy-duty trucks, buses, wheel hubs, and steering systems, and are capable of simultaneously withstanding high axial loads and radial loads. Their unique double-row angular contact design ensures excellent operational stability and long service life under extremely high pressure. These bearings typically feature precision-engineered contact angles and reinforced cages, making them critical components for ensuring driving safety and stable wheel and axle rotation in large vehicles.
