bearing means which bears or supports some moving element.
Inbetween bearing and shaft we introduce some lubricant to
minimise the friction or free rotation of the shaft.
ex: journal bearing, the latest technological bearings are
hydrodynamic bearings

there are two types of brg
1 - Anti friction brg
ex- ball brg, roller brg
2 - Friction brg
ex-bushor babbit metal brg
