Deep Groove Ball Bearing are particularly versatile.They are simple in design, non-separable,suitable for high and even very high speeds and are robust in operation,requiring little maintenance.Deep raceway grooves and the close conformity between the raceway grooves and the ball enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads,even at high speeds.Single row deep groove ball bearings are the most widely used bearing type.
