WebMar 27, 2024 · While fluid lubricants are typically preferred by design, the afore mentioned mechanical circumstances always exist in several places and thus the need for grease remains. As a result, greases are used in around 80 % of rolling elements bearings. History Grease was first used by the Egyptians on their chariot axles more than 3000 years ago. A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes. Other uses in… how can digital divide be tackled
