This listing is for 6 piece/s.Deep groove ball bearings are versatile self-retaining bearings with solid outer rings inner rings and ball and cage assemblies. They are of a simple design robust in operation and easy to maintain. They are available in open and sealed designs. Due to the raceway geometry and the use of balls deep groove ball bearings can support axial forces in both directions as well as radial forces. Deep groove ball bearings of Generation C were specially developed in relation to low noise levels and low frictional torque. They are particularly suitable for example for use in electrical machinery ventilators washing machines and power tools.
