Mechanical Assy dates back to the mid-1700s, when manufacturers realized that combining several applications into a single part drastically reduced prices while speeding up repairs. Interchangeable, mass-produced parts have been the foundation of mechanical assy from its inception and continue to be its backbone today. 

The Shaft Assy consists of a shaft, bearings, couplings, and other components that work together to facilitate rotational motion and power transmission.
