Generally, a bearing is a type of machine element that allows motion to be constrained, all while mitigating the amount of friction generated between moving surfaces. Bearings may come in numerous types that often differ in their shape, size, and performance characteristics, some being simplistic parts while others feature raceways,
rollers, and other elements. For their classification, bearings are often separated by their method of operation, the directions of applied forces and loads, and the motions they permit.
The most common types of bearings include plain and rolling-element types, those of which differ in whether or not raceways and rolling elements are present for friction reduction. Plain bearings are the most simplistic of all bearings, coming in the form of a shaft that rotates within a hole. There are various types of plain bearings that one may take advantage of depending on their need, and bushings are one of these subtypes.
Bushings are a form of plain bearing that is inserted into a housing, and they are often used for rotary applications where a bearing surface is required. Bushings are the most popular form of plain bearing, and they may be solid, split, or clenched in design. While a solid bushing features solid materials around the entire component, the split bushing has a cut along its length. The clenched bushing, meanwhile, differs from the split type with the presence of a clench across the cut for connecting parts.
With construction materials such as Babbitt, bronze, cast iron, and graphite, bushings can be made to be durable while also maintaining low friction and wear, ample temperature resistance, and corrosion resistance. Bushings also take advantage of lubrication as well, and the type of lubrication implemented will typically vary based on the type of bushing and the application it will serve. As bushings are beneficial for machinery featuring rotating or sliding shafts, they may be found within hydraulic pumps and motors, drill jigs, and other various equipment.
Rolling-element bearings, meanwhile, differ from bushings and plain bearings with the use of rolling elements that take on loads. With a balance between cost, weight, size, load capacity, friction, accuracy, and other factors, rolling-element bearings often serve as an optimal solution for numerous applications. Like other bearing variations, rolling-element bearings have various subtypes that one may take advantage of, those of which differ based on their rolling element. Generally, the five primary types of rolling elements found in such bearings are
balls, cylindrical rollers, spherical rollers, tapered rollers, and needle rollers. For their use, rolling-element bearings are commonly found within aviation cargo systems, solar panels, engines, power houses, automobiles, and much more.
