Rolling-Element Bearings

Rolling-Element Bearings is is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings and is one of the most important machine elements .

The characteristic feature of a roller bearing is that different rolling elements e.g. balls, rollers or needles, cylindrical rollers or tapered rollers are used between the inner and outer bearing race depending on the application purpose; the rolling of these elements between the races transforms undesirable slide friction into rolling friction. A distinction is made between two roller bearing variants: point-contact ball bearings and line-contact roller bearings. The friction surface of a roller bearing differs depending on the extent of the contact area.

• Line contact over larger contact areas allow greater loads to be transmitted.
• In the case of point contact with reduced surface, energy efficiency is achieved by minimising the friction surface.
