There are two types of loading to remember when talking about bearings: a radial load and a thrust load. The designations of most SKF rolling bearings follow a system that may consist of a basic designation with or without one or more prefixes and/or suffixes (Basic bearing designation system).Examples and the applicable options for single row angular contact ball bearings are given below. The concept is based on the fact that things roll more easily and with less effort than if you slide them. Most mechanical devices make use of one or the other type of bearings for their spinning parts. At first glance they may not seem all that different. Bearings have been around for hundreds of years and have many different uses, some of which include aiding in rolling (a tire), pulling, applications in hard drives, skateboards, and more. When installed, the inner race is often lightly pressed onto a shaft and the outer race held in a housing. When ball bearings are in motion their main job is to transfer the load from the outer raceway to the inner raceway. Also unlike ball bearings, roller bearings are not made to handle thrust loads. A radial load acts parallel to the axis of rotation of a bearing, allowing the bearing to rotate. A roller bearing is a cylindrical unit that is used to provide low-friction movement for a bushing or bearing block. As we know the journal bearing has long been the strength of a turbocharger and is still currently used within most turbochargers. Roller bearings perform better under shock and impact loading. As a general rule, ball bearings are used at higher speeds and lighter loads than are roller bearings. Ball Bearings 5, fig. A creature moving through the area at half speed doesn’t need to make the save. It is porous and self-lubricating. A typical ball or roller bearing consists of inner and outer raceways, a number of spherical, cylindrical, tapered, or semi-cylindrical elements separated by a carrier, and, often, shields and/or seals designed to keep dirt out and grease in.
