What kind of oil should be used in the bearing housing of an electric motor?

Using light machine oil in the bearing housing of an electric motor is appropriate because it provides the necessary lubrication while allowing for easy flow and heat dissipation. Light machine oils typically possess a lower viscosity, which helps them lubricate moving parts effectively and reduces friction between the bearing surfaces. This characteristic is crucial in electric motors, where bearings operate at varying speeds and temperatures.

Light machine oil also has good properties for preventing rust and corrosion, ensuring that the internal components of the motor remain protected. It can also help in reducing wear over time, extending the life of the bearings. Its formulation is designed specifically for the mechanical demands in such applications, making it a suitable choice compared to more viscous oils or inappropriate substances like water-based or vegetable oils.
