1. According to the structure type of rolling bearings, (1) bearings are divided into: 1) radial bearings - rolling bearings mainly used to bear radial load, with nominal contact angle from 0 to 45, according to the load direction they can bear or the nominal contact angle. According to the different nominal contact angles, it can be divided into radial contact bearings - radial bearings with a nominal contact angle of 0; radial angular contact bearings - radial bearings with a nominal contact angle greater than 0 to 45. 2) Thrust bearing - mainly used for bearing axial load, with nominal contact angle greater than 45 to 90. According to the difference of nominal contact angle, it can be divided into: axial contact bearing - thrust bearing with nominal contact angle of 90; thrust angular contact bearing - thrust bearing with nominal contact angle greater than 45 but less than 90.

2. According to the types of rolling elements, bearings are divided into: 1) ball bearings ---- rolling elements are balls; 2) roller bearings ---- rolling elements are rollers. Roller bearings can be divided into cylindrical roller bearings according to the types of rollers. The rolling body is the bearing of cylindrical roller. The ratio of length to diameter of cylindrical roller is less than or equal to 3; Needle-roller bearing - the rolling body is a needle bearing. The ratio of needle length to diameter is greater than 3, but the diameter is less than or equal to 5mm; Tapered roller bearing - the rolling body is the bearing of tapered roller; Self-aligning roller bearing - the rolling body is a spherical roller bearing. (3) Bearing can be divided into: 1) self-aligning bearing - the bearing whose raceway is spherical and can adapt to the angular deviation and angular movement between the axes of two raceways; 2) Non-aligning bearing (rigid bearing) - a bearing that can resist the angular deviation of the axis between the raceways.

3. According to the size of rolling bearings, bearings can be divided into: (1) miniature bearings - bearings with a nominal outer diameter of less than 26mm; (2) Small bearings - bearings with a nominal outer diameter of 28-55mm; (3) Medium and small bearings - bearings with nominal outer diameter ranging from 60 to 115mm; (4) Medium and large bearings - bearings with a nominal outer diameter of 120-190mm (5) large bearings - bearings with a nominal outer diameter of 200-430mm; (6) Extra large bearing - bearing with nominal outer diameter of more than 440mm.
