(1) can bear the load bearing at their direction, or nominal contact angle is different, and is divided into:bearing fact ory in china
1) radial bearings ---- mainly used to bear radial load bearing, its nominal contact angle from 0 to 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) thrust bearings ---- mainly used for axial load Rolling nominal contact angle greater than 45-90. Nominal contact angle is divided into: the axial contact bearings ---- nominal contact angle 90 thrust bearings: thrust angular contact bearings ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing.
(2) bearing their rolling body type, divided into:
1) ball bearings ---- rolling element ball:
2) roller bearings ---- the rolling body as roller. Roller bearing needle bearing roller types are divided into: cylindrical roller bearings ---- rolling body is cylindrical roller bearings, cylindrical roller length to diameter ratio of less than or equal to 3; --- - rolling body needle roller bearings, needle length and diameter ratio greater than 3, but less than or equal to 5mm diameter; ---- rolling body is tapered roller bearings tapered roller bearings; Spherical Roller scroll bearing eleven body is spherical roller bearings.
(3) bearing aligning their work ability, divided into:
1) aligning bearings ---- raceway is spherical, able to adapt to the angular deviation between the two raceways axis and angular motion of the bearing.
2) non-aligning bearing (rigid bearings) ---- the impedance roller bearing axis angle offset between Road.
(4) The number of columns bearing rolling elements, divided into:
1) single row bearings ---- having a rolling element bearing.abec bearings
2) double-row bearings ---- has two rolling element bearings.
3) The multi-row bearings ---- having more than two r olling element bearings, such as three, four bearings.
(5) bearing according member whether separate, divided into:
1) separable bearing ---- bearings with separable parts;
2) can not be separated bearing ---- bearing rings are not any free separation ultimately supporting bearings.
(6) bearing their shape structure (if any slot loading, whether inside the outer ring and ferrule of the shape of the wall of the structure, or even whether the cage, etc.) can also be divided into a variety of structural types.
B. Rolling size bearings classified according to their diameter size, divided into:
(1) miniature bearings ---- nominal diameter size range of 26mm below the bearing.
(2) small bearing ---- nominal diameter size range of 28-55mm bearing.
(3) small and medium-sized bearings ---- nominal diameter size range of 60-115mm bearing.
(4) in large bearings ---- nominal diameter size range of 120-190mm bearing.
(5) large bearing --- - nominal diameter size range of 200-430mm bearing.
(6) large bearings ---- nominal diameter size range of 440mm above the bearing.
