Bearings A bearing is a mechanical component that decreases friction between moving parts by restricting relative motion to only the desired motion. Why are Bearings necessary? Bearings' main purpose is to keep two moving elements from coming into direct touch with one another's metal surfaces. It prevents friction, heat accumulation, and eventually part wear and tear. Since low-friction rolling is used in place of sliding, energy is also saved. Additionally, they transfer to the housing the load of the rotating element. Radial, axial, or a combination of the two loads could be present. A bearing, as was already mentioned, limits the freedom of motion of moving parts to specific directions. Classification of Bearings: Depending on the force's direction · Bearing in Radius: The load supported by radial bearing is perpendicular to the shaft's axis. · Bearing of Thurst: The load acting along the sha...
