Bearings and its identification

Bearing and its types

A bearing – in its simplest form – is a friction reduction device placed within rotating components to aid efficiency of rotation. This is achieved as rolling produces much less friction force than sliding. The word bearing is derived from the verb “to bear”. A bearing is a machine element that allows one part to bear another. The main functions of bearings are

·??????To reduce friction between moving rotatory parts.

·??????To support rotating parts of a machine.

·??????To bear radial and thrust load.

According to design, load and shape, there are many types of bearings used in industries. The mains bearings can be classified as follows.

Now after the general over view of bearing let us find out how to identify bearing number for particular use case in industrial or domestic application. Throughout the world, there are various means by which a bearing is made. So, if you’re looking for “how to identify bearings by number?” we are going to discuss all the parameters and types of nomenclature bearing based on various numbering systems. let’s take a look at the basics of bearing number.

What is a Bearing Number

A bearing number itself is made from various other numbers that speak various other aspects of bearing. In general, a bearing number composes the information of bearing types, bearing series, bore size, and sealing. As the picture shows the position wise what the number represents.

Now below are the different tables which helps us identify the bearing by its type, series, bore size and sealings.

Coming to the conclusion, we can now easily decode bearing numeric details of most of the bearings. 32224 means “it is a tapered roller bearing having light toughness, with a bore size of 48 mm. Try some more bearings pattern number and find the correct bearing for your applications.?
