First, how to choose the grease?
Lubrication has a very important influence on the operation and life of SKF bearings, here to brief you choose grease general principles. Grease from the base oil, thickener and additives, grease the performance of different types and different brands of the same species vary greatly, different rotation limit allowed in the selection must pay attention. Grease performance is mainly determined by the base oil, generally low viscosity base oil for suitable temperature, high-speed, high viscosity at high temperature and high load. Thickeners also related to lubrication performance, thickening of the water determines the water resistance of the grease. In principle, different brands of grease should not be mixed, and even if the same kind of grease thickener, also because of different additives adversely affect each other.
Second, the bearing must be cleaned before installation?
Bearing surface is coated with anti-rust oil, you must use clean gasoline or kerosene carefully cleaned, then coated with clean, high-quality or high-temperature grease before installation. Cleanliness of rolling bearing life and influence of noise and vibration is very large. But we want to remind you that: totally enclosed bearings do not need to clean fuel.
