1. The type of rolling bearing structure classification

(1) direction or the public can bear the load that the contact angle, divided into:

1) Radial bearings ---- mainly used for rolling bearings to withstand radial loads, the nominal contact angle from 0-45. Nominal contact angle is divided into: radial contact bearings ---- nominal contact angle of 0 radial bearings: Angular contact bearings ---- nominal contact angle greater than 0-45 radial bearings.

2) The thrust bearing ---- mainly used for rolling bearing axial load and the nominal contact angle of greater than 45-90. Nominal contact angle is divided into: axial contact bearings ---- nominal contact angle 90 of the thrust bearings: angular contact thrust bearings ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing.

(2) According to the type of rolling element is divided into:

1) ball bearings ---- rolling element ball:

2) roller bearings ---- rolling element roller. Roller bearings according to the type of roller is divided into: Cylindrical Roller Bearings ---- rolling body is a cylindrical roller bearings, cylindrical roller length and diameter ratio of less than or equal to 3; Needle Roller Bearings --- - The rolling body is a needle roller bearings, needle length and diameter ratio greater than 3, but the diameter is less than or equal to 5mm; Tapered Roller Bearings ---- rolling element is a tapered roller bearing; Spherical Roller The bearings 11 rolling element is a spherical roller bearing.

(3) according to their work, divided into:

1) self-aligning bearing ---- raceway is spherical shaped to adapt to the angular deviation between the two raceway axis line and the angular motion of the bearing;

2) non-aligning bearings (rigid bearings) ---- impedance of the line angle offset between the axis of the raceway of the bearing.

(4) the number of columns of the rolling elements, divided into:

1) Single row bearings ---- with a rolling element bearings;

2) double-row bearings ---- two rolling element bearings;

3) multi-row bearings ---- more than two rolling element bearings, such as three, four bearings.

(5) According to their parts whether the separation, divided into:

1) separable bearings ---- bearings with separable components;

2) can not be separated bearing ---- bearings in the final matching rings are not any free separation of the bearing.
