Sliding bearings can also be lubricated with grease, lubricating grease in the selection should consider the following points:
(1)
bearing load, low speed, the cone should be selected a small amount of
grease, on the contrary to select a large cone penetration. High-speed tapered roller bearings NTN selection, mechanical stability, good grease. Special attention is the viscosity of the grease base oil to be lower.
(2)
Dropping point of the selected grease is generally higher than the
operating temperature of 20-30 ℃, the continuous operation at high
temperatures, careful not to exceed the allowable temperature range of
grease.
(3) sliding NTN bearings in the water
or wet environment work, you should choose good water resistance of
calcium, aluminum or lithium-based grease.
(4) choose a good adhesion of the grease.
