1. The radial bearing is mainly used for rolling bearings that accept radial load; its nominal touch angle is from 0° to 45°. It is different according to the nominal touch angle; it is further divided into:
.1) radial bearing with a nominal touch angle of 0°,
.2) angular touch radial bearing bearing with a nominal touch angle of 0° to 45°.
2. The thrust bearing is mainly used for rolling bearings that accept axial load; its nominal touch angle is 45°～90°. It is different according to the nominal touch angle; it is divided into:
.1) Axial touch bearing thrust bearing with a nominal touch angle of 90°,
.2) Axial touch thrust bearing with a nominal touch angle greater than 45° but less than 90°.
Bearings according to the type of rollover; divided into:
.1) The ball bearing roll is a ball.
.2) Roller bearing tumbler is a roller.
Roller bearings are based on roller types; they are further divided into:
1) Cylindrical roller bearing tumbling body is a cylindrical roller bearing,
2) Needle roller bearing rolling body is a needle roller bearing,
3) Tapered roller bearing tumbling body is a tapered roller bearing,
4) Spherical roller bearing tumbling body is a spherical roller bearing,
Bearings can be adjusted according to their ability;
.1) The self-aligning bearing raceway is spherical; it can be used to the angular error and angular motion between the two raceways.
.2) Non-aligning bearings (rigid bearings) Bearings capable of resisting the angular misalignment between the raceways.
The number of bearings in the roll is divided into:
.1) Single row bearings have a row of rolling bearings.
.2) Double row bearings have two rows of rolling bearings.
.3) Multi-row bearings have more than two rows of tumbling bodies and receive bearings in the same direction. For example: three-row, four-row bearings.
Bearings can be separated according to their components; divided into:
.1) Bearings that can be separated from the bearing can be separated from the bearing.
.2) Do not leave the bearing bearing at the end of the matching; the ferrule can not be free to separate bearings.
Bearings according to their outer diameter scale. Governance. 1) miniature bearing nominal outer diameter scale of 26mm or less bearing.
.2) Bearings with a nominal outer diameter scale of 28 to 55 mm for small bearings.
.3) Bearings with a nominal outer diameter scale of 60 to 115 mm for small and medium-sized bearings.
.4) Bearings with a nominal outer diameter scale of 120 to 190 mm for medium and large bearings.
.5) Bearings with a nominal outer diameter scale of 200 to 430 mm for large bearings.
.6) Bearings with a nominal outer diameter scale of 440 mm or more for extra large bearings.
