Double row deep groove ball bearings of 4200 series correspond in their structure and function to single row deep groove ball bearings 6200 series arranged in pairs. They have deep raceway grooves in the bearing rings and a narrow osculation between the raceway grooves and balls. However, they are slightly wider than single row deep groove ball bearings of the series 6200  with the same bore and outside diameter.

Double row ball bearings 4200 series have same design as single row deep groove ball bearings, but have a greater width. And they are able to carry axial loads in both directions in addition to radial loads.

Double row bearings 4200 series can be considered for bearing arrangements where the load carrying capacity of single row deep groove ball bearings is no longer sufficient, or axial loads in both directions and/or tilting moments must be supported in addition to radial loads, or a high load carrying capacity is required and the design envelope available in a radial and axial direction is relatively small.

Application

Deep groove ball bearings are frequently used in electric motor applications, commercial and industrial applications including generators, pumps, original equipment or replacement parts in motors, office automation, farm equipment, and conveyor rollers.
