Bearings are machine elements that support a shaft that has a load, so that its rotation or back and forth movement can take place smoothly, safely and have a long life.
The following are some characteristics of plain bearings:
Light and compact: Plain bearings are light and compact.
Impact resistance: Plain bearings are known for their impact resistance. Sliding friction: Plain bearings operate on the principle of sliding friction. Material: Plain bearings can be made from materials such as graphite, which is a dry lubricant, or an alloy of copper and graphite, also known as graphalloy. Uses: Bearings are commonly used in large engines, such as steam turbines and large two-stroke marine vessels, and in almost all internal combustion (IC) engines.
