Bearings are used to reduce friction between two moving parts while refrigeration is the process of cooling a space or substance.

• Bearings work on the principle of reducing friction between two moving parts by providing a smooth surface for them to roll or slide against each other.

• Refrigeration works on the principle of removing heat from a space or substance, which causes it to cool down.

• Bearings are commonly used in m...read more
