Each "bearings types" displays characteristic properties, based on its design, which makes it more, or less, appropriate for a given application. For example, deep groove ball bearings can accommodate moderate radial loads as well as axial loads. They have low friction and can be produced with high precision and in quiet running variants. Therefore they are preferred for small and medium-sized electric motors.

Spherical and toroidal roller bearings can carry very heavy loads and are self-aligning. These properties make them popular for example for heavy engineering applications, where there are heavy loads, shaft deflections and misalignments.

Rolling bearings fall into two main classifications: ball bearings and roller bearings. Ball bearings are classified according to their bearing ring configurations: deep groove, angular contact and thrust types. Roller bearings on the other hand are classified according to the shapeof the rollers: cylindrical, needle, taper and spherical.

Rolling bearings can be further classified according to the direction in which the load isapplied; radial bearings carry radial loads and thrust fag bearings carry axial loads.

Other classification methods include: 1) number ofrolling rows (single, multiple, or 4-row), 2) separable and non-separable, in which either the inner ring or the outer ring can be detached, 3) thrust bearings which can carry axial loads in only one direction, and double direction thrust bearings which can carry loads in both directions.

According to the demand of the machine, several types of bearings are introduced. These bearings serve different purposes and are shaped differently. Two of the main types, differentiated according to the load that they can withstand, are:

1. Axial bearing: Manage axial force

2. Radial bearing: Support radial machine

Ball bearings are typically capable of dealing with two kinds of loading condition; radial load and thrust load. Depending on the type of application the nachi bearing is used in, it may experience radial load only, thrust load only or a combination of both. A classic example being the car wheel as shown below.
