Deep groove ball bearings have deep, uninterrupted raceway grooves. These raceway grooves have a close osculation with the balls, enabling the bearings to accomodate radial and axial loads in both directions. These bearings are particularly versatile and are:simple in designnon separablesuitable for high and even very high speedsrobust in operation, requiring little maintenanceDeep groove ball bearings are the most widely used bearing type. Consequently, they are available from SKF in many designs, variants, series and sizes.
