A roller bearing is a bearing which carries a load by placing rolling elements (rollers or balls) between two bearing rings called races. Types of roller bearings Cylindrical roller Bearing They handle low thrust and high radial loads at high speeds. Spherical Roller Bearings They have two rings on the inner raceway that handle loads and misalignment concerns Needle Roller Bearings They ...
Bearings are one of the important machine elements used in many applications, which include rotating component. This supports another moving machine element permitting the relative motion between the rollingelement bearings consist of balls or rollers positioned between raceways.
ASTM's rolling element bearing standards provide the specifications and test methods pertinent to the design, property, and performance requirements of the mechanical component known as the rolling element bearing. Mechanical bearings, in general, permit constrained relative motion between two other mechanical parts, typically linear or rotational.
In the case of roller bearings, as the rolling element moves along the race it creates a pressure 'wedge' of lubricant in front of itself. Figure 4 explains how hydrodynamic lubrication and squeeze lubrication work together in rolling element bearings. The lubricant is a critical element in good roller bearing operation.

Rollingelement bearings are a precision, yet simple, machine element of great utility. In this report we draw together the current understanding of rollingelement bearings. A brief history of rollingelement bearings is reviewed in the Introduction, and subsequent sections are
Tapered roller bearings have the rolling elements under the form of frustum of cone. They roll on tapered surface which, if extended, converges towards a single point on the bearing axis. The rollers are guided tangentially by the cage and axially by the big rib of the inner ring, on which they have contact.

The tapered roller bearing's geometry allows true rolling motion of the roller between the raceways, which means the rollers are unlikely to skid or slide when unloaded. Other roller bearings have minimal load requirements to insure the roller actually rolls and does not slide between the raceways.
