.... as well as the long life To take full advantage of the increased load carrying capacity and improved wear resistance, the life of SKF Explorer bearings should always be calculated using the SKF rating life. In this calcu- lation, the life extending improvements to SKF Explorer bearings are taken into account by• an increased basic dynamic load rating, and• an increased SKF life modificationfactor a

Product data New performance class Page ............. 16Page ............. 24 The proof is in the performance … If an SKF Explorer cylindrical roller bearing is compared with any other cylindrical roller bearing, several unique design features will be discovered. These derive from the many improve- ments described before and make the SKF Explorer performace class bear- ings superior. The numerous “micro” improvements do not become obvious until the bearing goes into operation. It runs more quietly as well as longer – in fact much, much longer than any cylindrical roller bearing used so far – because it is an SKF Explorer bearing.

u /P) by 1,4 to take intoaccount the improved material and operating behaviour. All the product improvements de-scribed can be exploited, for example, • to increase service life of existingdesigns,• to maintain power output of newdesigns,• to increase power output of existingdesigns or• to increase power density of newdesigns.

Increase service life of existing designs Maintain power output of new designs

Don’t need to increase power output?Use an SKF Explorer bearing of equal size to:• Increase safety factor• Reduce vibration • Reduce heat generation • Increase service intervals • Increase machine uptime Use a smaller SKF Explorer bearing to: • Reduce overall dimensions to save on materialcosts and weight• Achieve a stiffer design• Reduce heat generation• Increase speeds

Increase poweroutput of existing designs Increase power density of new designs

Use a lower section height SKF Explorer bearing with the same outside diameter to:• Increase shaft size • Achieve a stiffer design • Operate at the same or higher speeds Avoid costly redesign by using an SKF Explorer bearing of equal size to:• Increase power density • Increase speeds • Increase loads 12
