Bearing in accordance with the load direction can bear or nominal contact angle, divided into:
1, radial bearings - mainly used to bear radial load bearing its nominal contact angle from 0 ° to 45 °. Nominal contact angle is divided into:
(1) radial contact bearings - Nominal contact angle of 0 ° radial bearings;
(2) The angular contact bearings to the heart - nominal contact angle of 0 ° ~ 45 ° bearing.
2, thrust bearings - mainly used for axial load Rolling nominal contact angle of 45 ° to 90 °. Different nominal contact angle, divided into:
(1) an axial contact bearings - nominal contact angle of 90 ° of the thrust bearing;
(2) angular contact thrust bearings - Nominal contact angle greater than 45 ° but less than 90 ° thrust bearing.deep groove ball bearing
Bearing rolling element types, divided into:
(1) The ball bearings - the rolling element ball.
(2) roller bearings - rolling body roller.
Roller bearings roller types are divided into:
1) cylindrical roller bearings - rolling body is cylindrical roller bearings;
2) Needle Roller Bearings - rolling body needle roller bearings;
3) Tapered roller bearings - rolling body is tapered roller bearings;
4) Spherical Roller Bearings - rolling body is spherical roller bearings;
Bearings, aligning their ability, divided into:
(1) self-aligning bearings - spherical raceway, able to adapt to the angular deviation between the two raceways axis and angular motion bearings.
(2) non-aligning bearing (rigid bearings) - the impedance roller bearing axis angle offset between Road.
Bearing the number of rows of rolling elements, divided into:
(1) single-row bearings - and having a rolling element bearing.
(2) double row bearings - two rolling element bearings.
(3) multi-row bearings - having more than two rolling element load bearing and is exposed to the same direction. Such as: three, four bearings.
Bearing whether the separation of its components, is divided into:
(1) separable bearings - bearings with separable parts.
(2) can not be separated bearings - bearing rings are not any free separation bearing final matching.miniature bearing
Bearing their diameter size, divided into:
(1) miniature bearings - nominal diameter size range of 26mm below the bearing.
(2) small bearings - nominal diameter size range of 28 ~ 55mm bearing.
(3) small and medium-sized bearings - nominal diameter size range of 60 ~ 115mm bearing.
(4) in the large bearing - nominal diameter size range of 120 ~ 190mm bearing.
(5) large bearings - nominal diameter size range of 200 ~ 430mm bearing.
(6) the oversize bearings - nominal diameter size range of 440mm above the bearing.
