Bearings in motion systems. Bearings are simple machine elements crucial for motion applications. They usually consist of smooth rollers or metal balls and smooth inner and outer surfaces known as races against which rollers or balls roll. These rollers or balls act as the load carrier for the device, allowing it to spin freely.

From (a), we see the force vectors involved in preventing the wheel from slipping. In (b), point P that touches the surface is at rest relative to the surface. Relative to the center of mass, point P has velocity, where R is the radius of the wheel and . is the wheel's angular velocity about its axis. Since the wheel is rolling, the velocity of P with respect to the surface is its velocity ...
