SKF bearing grease selection - Nodes beari...

SKF bearing grease selection. Selecting a SKF grease can be a delicate process. Poor lubrication accounts for more than 36% of premature bearing failures. If including contamination, this number rises to well above 50%. The importance of proper lubrication and cleanliness is self-evident in the determination of bearing life.

It is therefore critical that engineers select the most appropriate grease for the bearing and the application it is operating in. Not only will correct selection prolong the life of the bearing, enabling it to operate at its full capacity, but it also ensures smoother running behaviour and improved operational safety.

Figure 2 shows how k relates to both lubricant selection and expected bearing life. At k values below 1, it is generally accepted that EP additives will be required to mitigate the effects of boundary lubrication conditions. As k approaches 1, the life expectancy approaches the rated life expectancy L of the bearing according to DIN ISO 281.
