How many kinds of bearings are divided into?
The simplest division is divided into two kinds, rolling bearings and plain bearings
For many, the most common of 0 types of 1 kinds of deep groove ball bearings, self-aligning ball bearings, spherical roller bearings 2, 3 class 6 kinds of spherical roller bearings, angular contact bearings, 7 types of 8 kinds of tapered roller bearings, thrust ball bearings, 9 types of thrust roller bearings, joint bearings and needle roller bearings, linear bearings and so on.
Bearings are used to determine the rotation axis and other parts relative motion position, supporting or guiding role of parts and components.From the big classification, it can be divided into sliding bearings, rolling bearings and linear moving rolling parts.Among them, the sliding bearings are divided into: open type radial bearings, integral radial bearings, self radial bearings, oil bearing, nylon bearings. The rolling bearing is divided into: deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings, spherical roller bearings, needle roller bearings, angular contact ball bearings, tapered roller bearings, thrust ball bearings, thrust roller bearing.The rolling element of linear motion is divided into rolling linear guide pair, rolling linear guide sleeve pair and rolling spline pair.If they continue to divide, they also have their own varieties and models, here
The bearings can be divided into sliding bearings and rolling bearings according to the way of friction. The rolling bearings can be divided into ball bearings and roller bearings according to the shape of the rolling bodies,The ball bearings can be classified according to the new model:0 double row angular contact ball bearings1 automatic self-aligning ball bearing4 double row deep groove ball bearings5 thrust ball bearings6 single row deep groove ball bearings7 single row angular contact ball bearingsQJ four point contact ball bearingRoller bearings according to the new model can be divided into:2 spherical roller bearings (also called domestic roller bearings)3 tapered roller bearings8 thrust roller bearingsN cylindrical roller bearingsThere are many other series of bearings, such as needle roller bearings, joint bearings, wheel bearings, linear bearings, self-lubricating bearings, etc., their code name is more complex, so not one by one example.Hope to be of help to you
A lot of ah, a lot of samples are introduced, but you can see the national standard GB/T271-2008 classification of rolling bearings
