The performance of any moving machine largely depends on the accuracy of installation and erection. Levelling and alignment are the basic maintenance practices carried out during the commissioning of any type of machinery which ensures reliability. With this e-learning module, the audience will enhance their knowledge of levelling and alignment. In this module, one can learn the basic concept of leveling, various methods of levelling, critical checkpoints, and standards required to be maintained during the levelling. 

A coupling is a mechanical component that associates the drive shaft and driven shaft of a motor, pump, etc., to conduct power. Shaft couplings propose mechanical flexibility, support resistance for shaft misalignment. 

Bearings have played a crucial role in the nascent Industrial Revolution, grant the new industrial machinery to operate accurately. The term “Bearing” is borrowed from the verb “to bear”, a bearing being a machine element that allows one part to bear (i.e. to support) another.
