How many classifications are there for self-aligning ball bearings?

wallpapers Industry 2021-04-07
Bearings are classified according to the load direction or nominal contact angle they can withstand,the self-aligning ball bearings are divided into:
1) Radial bearings-Rolling bearings mainly used for bearing radial loads, with a nominal contact angle ranging from 0 to 45.
According to the different nominal contact angles, it is 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 bearings-rolling bearings mainly used for bearing axial loads, with a nominal contact angle greater than 45 to 90.
According to the different nominal contact angles, it can be divided into:
Axial contact bearing-thrust bearing with a nominal contact angle of 90:
Thrust angular contact bearings-thrust bearings with a nominal contact angle greater than 45 but less than 90.
Bearings are classified according to the types of rolling elements:
1) Ball bearings-the rolling elements are balls:
2) Roller bearings-the rolling elements are rollers. According to the types of rollers, roller bearings are divided into:
Cylindrical roller bearing-the rolling element is a cylindrical roller bearing, and the ratio of the length to the diameter of the cylindrical roller is less than or equal to 3;
Needle roller bearing-the rolling element is a needle roller bearing, the ratio of the length of the needle roller to the diameter is greater than 3, but the diameter is less than or equal to 5mm;
Tapered roller bearing-the rolling element is a tapered roller bearing;
Spherical roller bearings are bearings in which the rolling elements are spherical rollers.
According to whether the bearing can be adjusted during operation, the self-aligning ball bearings are divided into:
1) Self-aligning bearing-the raceway is spherical, which can adapt to the angular deviation and angular movement between the axis of the two raceways;
2) Non-aligning bearings (rigid bearings)-bearings that can resist the angular deviation of the axis between the raceways.
Bearings are divided into the number of rows of rolling elements:
1) Single row bearings-bearings with one 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 and four-row bearings.
Bearings can be divided into:
1) Separable bearings-bearings with separable parts;
2) Non-separable bearing-After the bearing is finally matched, the ring can not be separated freely.
