Advantages: Grease has a long service life, less oil supply, and does not need to be added frequently. Grease lubrication is more advantageous for friction parts where it is difficult to add oil frequently. Grease is usually used for heavy loads, low speeds, high speeds, high temperatures, low temperatures, extreme pressures, and harsh conditions with impact loads. It is also suitable for lubrication of intermittent or reciprocating parts. Grease has a strong ability to maintain on the friction surface and good sealing. Some mechanical seals are not tight, and the use of grease can prevent moisture, dust and other mechanical impurities from entering the friction surface. Grease is also suitable for the friction parts of machinery operating in humid and dusty environments.
Grease-lubricated machines can prevent dripping and splashing oil from contaminating the product, and can operate normally in a vertical position without oil leakage. Grease has strong adhesion on the metal surface and can protect the metal from rusting for a long time. The operating temperature range of grease is wider than that of lubricating oil. When lubricating with grease, no complex sealing device and oil supply system are required, which can simplify the mechanical structure.
Disadvantages:
Grease cooling and heat dissipation effect is not as good as lubricating oil. When equipment lubricated with grease is started, the friction torque is large. Replacing grease is more complicated than replacing lubricating oil.
