Double row deep groove ball bearings correspond in their structure and function to a pair of single row deep groove ball bearings. They are designed for high to very high speeds and are used where the load carrying capacity of single row deep groove ball bearings is not sufficient
Double row deep groove ball bearings are wider than single row deep groove ball bearings of the same bore and outside diameter but have a significantly higher load carrying capacity
Sealing
Double row deep groove ball bearings are not sealed
Lubrication
The bearings are open and are greased using a high quality grease.
Operating temperature
Open deep groove ball bearings can be used up to an operating temperature of +120 °C
