Four-row cylindrical roller bearings are kind of separable bearings. The rings and roller components are easily separable.

Deep groove ball bearings, also known as DGBB bearing, are the typical rolling bearings which have the most widely application.
Basic deep groove ball bearings of different sizes are made up of one inner ring, one outer ring, one cage and a group of balls. It can bear both radial and axial load capacity. Therefore, it can also be divided into axial deep groove ball bearing and radial deep groove ball bearing.

It is widely applied to low speed and medium speed rolling mills. The internal clearance is adjusted and makes it easier to operate.
