Rolling bearing classification summary:
1. According to the type of rolling bearing structure
(1) Bearings are classified according to their different load directions or nominal contact angles:
1) Radial Bearings - Mainly used for rolling bearings that bear radial loads with nominal contact angles from 0 to 45.
According to different nominal contact angles, it is divided into:
Radial contact bearings - radial bearings with a nominal contact angle of 0:
Concentric angular contact bearings - Centripetal bearings with a nominal contact angle greater than 0 to 45.
2) Thrust bearings—mainly used for rolling bearings with axial loads, with nominal contact angles greater than 45 to 90.
According to different nominal contact angles, it is divided into:
Axial contact bearings - thrust bearings with a nominal contact angle of 90:
Axial angular contact bearings - thrust bearings with a nominal contact angle greater than 45 but less than 90.
(2) Bearings are classified according to the type of their rolling elements:
1) Ball bearings—balls are balls:
2) Roller bearings—rollers are rollers. According to the roller type, roller bearings are divided into:
Cylindrical roller bearings - rolling elements are cylindrical roller bearings, the ratio of the length and diameter of the cylindrical roller is less than or equal to 3;
Needle roller bearing - rolling element is the needle roller bearing, the ratio of the length and diameter of the needle roller is greater than 3, but the diameter is less than or equal to 5mm;
Tapered roller bearings ---- rolling elements are tapered roller bearings;
Spherical roller bearings are spherical roller bearings.
(3) The bearing can be adjusted according to its work, divided into:
1) Self-aligning bearing ---- The raceway is spherical and can adapt to the angular misalignment and angular motion between two raceway shafts;
2) Non-aligning bearings (rigid bearings) --- bearings that can deflect the angular misalignment between raceways.
(4) According to the number of rows of rolling elements, the bearing is divided into:
1) single row bearing - bearing with a row of rolling elements;
2) Double row bearings - bearings with two rows of rolling elements;
3) Multi-row bearings - bearings with more than two rows of rolling elements, such as three-row, four-row bearings.
(5) Bearings can be separated according to their components, divided into:
1) Separable bearing ---- bearing with detachable parts;
2) Inseparable bearing ---- bearing after the final support, the bearing ring can not be free to separate any bearing.
