Proven to be better thanks to X-life – Schaeffler optimizes its product range
(Bearing NEWS Issue 03, 02/2015)
X-life is the seal of quality for ultra-high performance products of the brands INA and FAG. They are characterized by higher basic dynamic load ratings compared to conventional products, resulting in a longer rating life and operating life.
X-life opens up new possibilities in design and engineering: | |
![]() | If the load and design envelope are unchanged, X-life bearings have a longer rating life. In this case, longer intervals are possible between maintenance operations. |
![]() | Conversely, an X-life bearing with the same design envelope and the same rating life can support higher loads. |
![]() | Where both the rating life and the load are unchanged, the use of X-life bearings results in greater performance density, optimization of the design envelope and a reduction in design mass. |
As a result, X-life bearings make an essential contribution to improvements in the overall cost-effectiveness of the application under the Total Cost of Ownership principle. |

Higher performance is achieved through the use of state-of-the-art manufacturing techniques as well as improvements in internal design. These give better, more uniform surface quality and contact surfaces, leading to optimized load distribution in the bearing.
