Rolling bearings are different according to their acceptable load direction or nominal touch angle;
1; radial bearing: the first to be used for rolling bearings bearing radial load; its nominal touch angle from 0 degrees to 45 degrees. According to the nominal touch angle is different; is divided into: (nominal touch angle is said to be the ferrule in the rolling bearing The angle between the normal to the roll touch and the plane perpendicular to the bearing axis)
1) Radial touch bearing: a radial bearing with a nominal touch angle of 0 degrees,
2) Angular touch radial bearing: a bearing with a nominal touch angle of 0-45 degrees.
2; Thrust bearing: the first to be used for rolling bearings that accept axial load; its nominal touch angle is 45-90 degrees. It is different according to the nominal touch angle; it is divided into:
1) Axial touch bearing: a thrust bearing with a nominal touch angle of 90 degrees,
2) Angular touch thrust bearing: a thrust bearing with a nominal touch angle greater than 45 degrees but less than 90 degrees.
Bearings according to the type of rollover; divided into:
1; ball bearing: roll body for the ball
2; Roller bearing: Roller is a roller roller bearing according to the roller variety; it is divided into:
1; cylindrical roller bearing: the rolling element is a cylindrical roller bearing,
2; needle bearing: the rolling body is a needle roller bearing,
3; Tapered roller bearing: Roller bearing is a tapered roller bearing
4; spherical roller bearing: the rolling body is a spherical roller bearing.
Bearings can be adjusted according to their ability;
1; self-aligning bearing: the raceway is spherical; can be used to the angular error between the two raceway axis and the angular movement of the bearing.
2; non-aligning bearings (rigid bearings): bearings that can offset the axial angular deviation between the raceways.
The number of bearings in the roll is divided into:
1; single row bearing: bearing with a row of rolling elements,
2; double row bearing: bearing with two rows of rolling elements,
3; multi-row bearing: bearing with more than two rows of rolling elements and receiving loads in the same direction.
Bearings can be separated according to their components; divided into:
1; can be separated from the bearing: bearing with separate components,
2; Do not leave the bearing: the bearing is at the end of the matching; the ferrule can not be free to separate bearings.
