With all of the big brands telling us that their spherical roller bearings offer superior life and cooler running than their competitors, can they all be correct?
With each brand offering compelling reasons to buy them;
SKF Explorer spherical roller bearings boasting the market leading brand with advanced roller geometries and patented self-guiding roller system with superior heat treatment processes.
FAG X-Life spherical roller bearings statement of higher cost effectiveness and operational security.
NSK HPS spherical roller bearings highest load ratings with twice the life of other brands and increased limiting speeds.
Timken spherical roller bearings pioneering a spherical revolution with bearings that run cooler and longer than rivals.
Lets take a closer look at each brand for a common industry bearing size 22220 to see how the compare on the most basic level ‘basic dynamic load rating’. This is an indication of what bearing life you could achieve and forms an integral part of L10 bearing life calculations.
|Basic Dynamic Load Rating C||433kN||430kN||455kN||435kN|
As you can see from the table there is one brand which should be lasting longer in similar bearing applications than the other big brands. But does any of this matter, or should you go for the cheapest option available at the time?
