High speed fly wheel is a mechanical device with a disc or wheel that can store rotational energy. Cast iron is typically used to make flywheels for automobiles. It rotates in tandem with the engine thanks to its attachment to the crankshaft. Our offering stores energy in the form of kinetic energy as it rotates. Its energy is used to keep the engine's crankshaft and other moving parts in motion when the engine is not in use. The function of the high speed fly wheel in car engines is to generate energy for the piston compression stroke.
