Assortment of Bearings

A machine element that constrains relative motion to only the desired motion
Reduces friction between moving parts
Provides free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts
Experience loads in two basic directions

Exploded View of Bearing

- - Made From high-purity chrome allow
  - The rings have either a groove or track that allows the a ball bearing or a roller bearing to sit in

- - Guides the rolling elements and keeps them spaced out
  - Typically made from steel

- - Radial forces are applied along the radius of the bearing or perpendicular to the shaft
  - Axial forces are applied along the axle through the bearing
