Bearings are mechanical components that are placed between two parts to allow easy and controlled rotation between them They minimize the amount of resistance and can provide for rotation or linear motion Commonly bearings are made up of rolling elements which are either balls or rollers confined between an inner and an outer ring It is through the rolling movements of the bearing that it can enable rotational or linear movement while forces act on it and reduce the losses that may be occasioned by friction They are vital elements found in automotive aerospace industrial machinery and home appliances among others since they enhance efficiency and reliability Different types of bearings like ball bearings and roller bearings are a crucial component of nearly all devices in modern technical processes due to their ability to regulate precision and motions
