Merry Christmas

Angular contact ball bearing, also known as acbb bearing, is a kind of inseparable bearing, the side shoulders of inner ring and outer ring are uneven. In order to increase the load capacity, one of the side shoulder will be lower than the other. This kind of bearings has raceways both on inner ring and outer ring.

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.

Spherical thrust roller bearings is a kind of thrust rolling bearing. They allow low friction rotation and angular deviation and are designed to bear radial load and one-way axial load.
