Thrust bearing - Wikipedia

Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low thrust applications where there is little axial load. Cylindrical thrust roller bearings consist of small cylindrical rollers arranged flat with their axes pointing to the axis of the bearing. They give very good carrying capacity and are cheap, but tend to ...

Ball screw - Wikipedia

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction.A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.

How the Physics of Football Works | HowStuffWorks

When the ball leaves the punter's foot, it is moving with a given velocity (speed plus angle of direction) depending upon the force with which he kicks the ball. The ball moves in two directions, horizontally and vertically. Because the ball was launched at an angle, the velocity is divided into two pieces: a horizontal component and a vertical component.

What Are Ball Bearings Used For? - provenproductivity

Ball bearings work by transferring the load from the outer race to the ball and on to the inner race. Everything is able to spin smoothly since the spherical shape of the ball only touches the inner and outer race at very small points. However, this can also be a hindrance as well if the bearing is not used properly. Because of the small area ...
