deep groove ball bearings
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 Deep groove ball bearings are the most widely used bearing type. Consequently, they are available from us in many designs, variants, series and sizes.
The deep groove ball bearings are available for shaft diameters ranging from 3 to 700 mm.

Double row deep groove ball bearings
Double row deep groove ball bearings correspond in design to single row deep groove ball bearings. They have deep uninterrupted raceways and high conformity between the balls and raceways. They are able to carry axial loads acting in both directions in addition to radial loads.
Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate. For the same outside and bore diameters, double row bearings are slightly wider than single row bearings but have considerably higher load carrying capacity than single row bearings in the 62 and 63 series.
The large-size bearings which are designed for heavily loaded, slowly rotating applications are without cage.
Single row deep groove ball bearings 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 balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads, even at high speeds
