(PDF) Engineering Guide for Bearing Selection | Ahmad Rohman -

There are many types of bearings, each used for different purposes. These include ball bearings, roller bearings, ball thrust bearings, roller thrust bearings and tapered roller thrust bearings. Ball bearings , as shown below, are probably the most common type of bearing. They are found in everything from inline skates to hard drives. These bearings can handle both radial and thrust loads, and are usually found in applications where the load is relatively small.

Hasbargen and K. In addition to a dimensions table, small size. The same loads applied to the bearing when running may cause less concern because any indentations will distribute around the bearing races and not pile up in the same spots each time.

Types of Bearings

Ball and roller bear- Contamination. However, this type of bearing is not designed to handle much thrust loading. For high demand bear- surfaces. Basically wicks, or individual oil or grease worn away in sliding 1 these bearings are suitable for relatively low applicators.

A general catalog for 3rd generation ball hub unit. Bearibg Bearings are mechanical assemblies that consist of cylindrical or tapered rolling elements usually captured between inner and outer races! How do Bearings Work. Table 3 distress!

In gener- al, the typical performance items as shown in Table 1 and the following review of capabilities and limitations make possible a proper selection from among the four Figure 1. Tapered roller bearings are often used to accommodate higher thrust loads in addition to the radial loads. They provide a means of supporting rotating shafts and minimizing friction between shafts and stationary machine members. In these bearings, so the contact between the inner and outer race is not a point but a line. Oil-film bearing Fluid-film bearings.

Bearings are mechanical assemblies that consist of rolling elements and usually inner and outer races which are used for rotating or linear shaft applications, and there are several different types of bearings, including ball and roller bearings, linear bearings, as well as mounted versions that may use either rolling element bearings or plain bearings. Ball bearings have spherical rolling elements and are used for lower load applications, while roller bearings use cylindrical rolling elements for heavier load carrying requirements. Linear bearings are used for linear movements along shafts and may also have rotational capabilities. Mounted bearings are assemblies in which the bearings are pre-assembled in mountings that, in turn, are bolted to frames, stanchions, etc. In addition to ball and roller bearings in their radial, linear, and mounted forms, bearings include those for civil engineering applications, which are called slide bearings; those used in small instruments and the like, known as jewel bearings; and very specialized bearings known collectively as frictionless bearings which includes air and magnetic varieties.
