There are various types of bearings used in mechanical systems, each with specific uses such as reducing friction and supporting loads.

• Ball bearings: used for low friction applications like wheels and conveyor belts

• Roller bearings: used for heavy radial loads like in car transmissions

• Thrust bearings: used for axial loads like in propellers

• Plain bearings: used for high load capacity and shock resistance like in cranksha

A compressor works by increasing the pressure of a gas to compress it into a smaller volume.

• Compressors use a motor to drive a piston or rotor that compresses the gas.

• The compressed gas is then stored in a tank or released for use in various applications.
