Deep Groove Ball Bearings

Deep Groove Ball Bearings mainly take radial load as well as take moderate axial load. With less coefficient of friction, high limiting speed, large size range and variations or structure, they are suitable for precision instrument, low noise motors, automobiles, motorcycles, and other common machinery as a widely used type of bearings in machinery industry.
