6 Different Types of Bearings

26 07 2020  Generally all types of machinery are provided with supports for rotating shafts the supporting device is known as a bearing other words a bearing is a machine element that constrains relative motions and used to reduce the friction between moving parts. Bearing employs to support guide and restrain moving the element.

Elements of Translating Mechanical System

Note that the spring and friction elements for the rotating systems will use capital letters with a subscript r K r B r while the translating systems will use a lowercase letter. One of the difficulties in working with rotating systems as opposed to those that translate is that there are often multiple ways to make diagrams of the systems.
