Sliding bearing is lubricated by grease to, when choosing grease should consider the following points:
(1) the bearing load, low speed, small grease should choose cone into the degree, on the other hand to choose large cone into the degrees.High-speed NTN bearing choose cone into the degree of small, good mechanical stability of grease.Pay special attention to the lower the viscosity of base oil of the grease.
(2) the choice of grease drop point generally higher than the working temperature of 20-30 ℃, at high temperature under the condition of continuous operation, be careful not to exceed the allowed to use the temperature range of the grease.
(3) sliding NTN bearing in water or damp environment, should choose water resistance good calcium, aluminum or lithium base grease.
(4) has a good adhesion of grease.
