What is Axial Load and Radial Load?
Concept: Axial load, also known as thrust load, is a force applied parallel to the axis of a mechanical component or bearing. It tends to move components along the axis, either towards or away from the source of the force. The pushing or pulling a component in a straight line is the simplest example of an axial load. Example 1: Elevator in a ...
