In efficiently operating equipment, mechanical components reduce friction and carry loads for linear or rotary motion. They are designed to change input to output speed ratios. Each one is designed to perform a specific function to increase the efficiency and provide exacting precise control.
As with many aspects of engineering, mechanical components are the small, insignificant part of equipment that we tend to ignore but perform a vital function. From the family car to the most complex industrial devices, these small pieces ensure smooth and inexpensive operation.
