Smooth bearing grease selection criterion is what?

Smooth fat as bearing smooth one material, under special conditions, using the smooth fat can also constitute a separate slide appearance complete a layer of oil film. Because of its mobility is poor, so no cooling effect, commonly used in the liquid friction bearing the request is not high, difficult to get a lot of oil supply or special and shaking of low speed and heavy loading. Smooth bearing grease selection criterion is what? General conditions have three conditions: (1) unit of high pressure and sliding speed is low, choose cone into the smaller type, instead choose cone into the degree of the larger species; (2) the drop point of smooth fat used a - Work should be higher than the bearing temperature of about 20 - 30 degrees, in order to avoid work smooth fat loss too much; (3) in the water spray or humid environment, should choose waterproof strong calcium base or aluminum smooth fat, when temperature is higher, should choose calcium sodium based or complex smooth calcium base grease.
