General Types of Bearings and How They Work - ThomasNet
Generally speaking, a bearing is a device that is used to enable rotational or linear movement, while reducing friction and handling stress. Resembling wheels, bearings literally enable devices to roll, which reduces the friction between the surface of the bearing and the surface it's rolling over.

What is a "floating" bearing arrangement? | Bearing Tips
There are usually two bearings involved in the rotating machine components of a mechanical system. Depending on several factors such as load, cost and necessary running accuracy, engineers use a few different types of bearing arrangements. One of these types is a "floating" bearing arrangement.
NSK - Types
Cylindrical Roller Bearings Cylindrical Roller Bearings use line contact between the rolling elements and the raceways, which optimizes the distribution of stress factors at the point of contact. This arrangement means that cylindrical roller bearings have a very high radial load rating.
Spindle Bearing Arrangements & Bearing Preload Design
Spindle bearings are single-row angular contact bearings, with 15° and 25° contact angles, but many specials are available when the application demands. Important characteristics of spindle bearings include contact angle, materials, precision, preload and bearing arrangement and more.

rolling bearing applications throughout the world and the know-how of CR in respect of seals has strengthened SKF competence in these fields. It also forms a solid foundation for further inno-vations in bearing and seal technology. Whatever the bearing arrangement, it comprises not only the bearing but also the components immediately associ-
When ball and roller bearings within the same dimension series are considered, the roller bearings have a larger load capacity and are also capable of withstanding greater vibration and shock loads. ... 2.3 Selection of bearing arrangement Shafts or axles are generally supported by a pair of bearings in the axial and radial directions. The bearing
Ball Bearing Design & Application - CED Engineering
The radial ball bearing is designed to accommodate primarily radial loads but the deep groove type will support bidirectional thrust loads up to 35% of the radial load before bearing life becomes progressively shorter. The assembled radial bearing is inseparable and may be equipped with seals, shields, and/or snap rings (discussed later).
