Definition: Grease anti-wear performance refers to the ability of grease to prevent wear on lubricated components in high-load operating equipment. ① For metal machinery, due to the relative motion of metal surfaces, friction causes metal to separate and peel off from the surface, resulting in a loss of weight or changes in the volume and…
Definition: Refers to the ability of grease’s structural system to resist deformation and flow under mechanical shear forces. ① Mechanical stability is an important performance characteristic of grease and a key factor affecting its service life. ② The mechanical stability of grease mainly depends on the type of thickener and the preparation process. ③ Methods…
Definition: Refers to the ability of grease to resist being washed out of ball bearings by water under test conditions. This is a critical factor when selecting grease for machinery operating in humid environments. ① Under specific conditions, the percentage mass of grease washed away by water is measured. The smaller the loss, the less…
Definition: Refers to the degree to which grease hinders the rotation of low-speed ball bearings (open type 204 bearings) under low-temperature conditions. ① Low-temperature torque indicates the low-temperature performance of grease. Using a torque of 9.81 N·cm (1000 g·cm), the lowest temperature at which the bearing completes one rotation within one minute is measured as…
