Performance requirements of high temperature deep groove ball bearing grease
Due to the wide application of deep groove ball bearings in various equipment, in order to meet the requirements of different use environments, the bearings also have different requirements on the manufacturing materials and related accessories. Among them, the performance requirements of professional greases used on deep groove ball bearings that require high-speed operation under high temperature environments are as follows.
1. It has a long service life under high temperature environment, has good oxidation resistance, and prolongs the service life of high temperature deep groove ball bearings.
2. The grease will not be lost during high-temperature operation. Even at 180 ℃, the grease can maintain a certain consistency and does not soften.
3. The mute effect is better, because the fiber hardness of high temperature deep groove ball bearing grease is generally larger, so the quiet performance of high temperature bearing grease is not as good as lithium base grease in the test.
4. Less grease leakage. When the deep groove ball bearing is running at high speed, the grease will withstand high frequency repeated shearing and large centrifugal force, and the grease must be able to return to the raceway in time without being thrown out.
