BEARINGS A bearing is a machine element that constrains relative motion between moving parts to only give the desired motion. The design of bearing may be provide for free linear movement of the moving parts or free rotation around a fixed axis or it may prevent motion by controlling the vectors of normal forces that bear on the moving parts .They are mainly used to minimize the friction between moving parts. The invention of the rolling bearing, within the sort of wood rollers supporting, or bearing, associate object being affected is of nice antiquity, and may predate the invention of the wheel. The ball bearing was originally described by GALILEO in the 17 th century. Bearings played a significant role in technological revolution allowing the new industrial machinery to work with efficiency. There are various types of bearings. The most common bearing is plain bearing which uses lubricant between the rubbing surfaces. Types of bearings: Plain Bearing Journal bearing Sle...
