The oil and fat is a semi-solid lubricant composed of a base oil, a tackifier, and an additive, and it is necessary to select a grease suitable for the purpose according to the combination thereof.
(1) Base oils Most of the base oils are made of mineral oil. However, in order to improve heat resistance and low-temperature fluidity, synthetic oils such as silicone oil are also used.
(2) Tackifiers Tackifiers include various compounding agents and the like, and are properties that control mechanical stability, water resistance, and temperature range.
(3) Additives Add various additives depending on the purpose of use. Extreme pressure additives make the impact load and heavy load characteristics upward.The oxidizing additive prevents oxidative degradation when there is no replenishment for a long time. Anti-rust additives prevent corrosion on the bearings and their surroundings.
