Deep groove ball bearings are the most common types of bearings which are durable and easy to maintain. They have a simple structure consisting of an outer ring, an inner ring, a ball, and a cage available in many executions and sizes. They are available in single and double-row designs as well as in open and sealed variants.
Compared with the other kinds of bearings, deep groove ball bearings have a very low frictional coefficient and high speed limit making them unable to endure high impact and heavy loads.
Deep groove ball bearings are mainly used to bear radial loads. They can do the job of an angular contact bearing and bear connected loads in radial and axial direction with larger radial internal clearance.
