Low noise and high temperature resistant grease

When the bearing is in operation, noise will occur due to friction. At this time, low-noise and high-temperature grease should be used to reduce the noise and loss of the bearing. So what is low noise and high temperature resistant grease?

First, what is low noise and high temperature resistant grease

Low noise bearing grease is a kind of high temperature resistant grease. It is prepared by using lithium base as the thickener of the grease and high precision mineral oil as the base oil, adding additives. Lithium soap has a high degree of cleanliness, which can effectively reduce the bearing oscillation value, so low noise and high temperature resistant grease can effectively reduce the noise of the bearing; meanwhile, low noise and high temperature resistant grease also has good anti-corrosion function, which can prevent the bearing Corrosion occurred during operation.

Application range of low noise and high temperature resistant grease

Low noise and high temperature resistant grease is suitable for small and medium-sized rolling bearings and low-load rolling bearings. Low-noise bearing grease has good water resistance and can function as a lubricant in relatively humid environments. Low-noise bearing grease has a certain high-temperature and high-temperature resistance function, and can still provide good lubrication at 120 ° C.

Third, bearing noise in different situations

Bearings will emit noise under normal circumstances, but some sounds are abnormal. Today I will tell you that those sounds are abnormal.

If the bearing is in good condition, a low whining or buzzing sound will be announced during operation; if the bearing announces a sharp and irregular sound, this indicates that the bearing is not in good condition; if the bearing is running, a sharp squeak is announced , It clarifies that the bearing does not use appropriate low-noise and high-temperature grease; if the bearing announces a metallic sound, this clarifies that there is a problem with the gap between the bearings; if the bearing announces a smooth and loud sound, this clarifies that there is a problem on the bearing outer ring track, In general, it is due to the presence of dents; if it is intermittent noise, this indicates that the rolling elements of the bearing are damaged, and severe and large noise will cause irregular bearing damage.
