X-life, as a FAG and INA product, offers design engineers new design opportunities. With the application of advanced manufacturing technologies, the entire contact surface of the rolling elements and raceways becomes better and more consistent. As a result, under the same load conditions, the stress on the rolling elements and their mating surfaces is significantly reduced. Therefore, the X-life bearings will have a longer service life under the same operating conditions. On the other hand, under the same rated life conditions, they can withstand higher loads. With these optimized features, X-life bearings open up new application prospects, such as reducing the size of support bearings. Moreover, the higher cost-performance ratio enhances the overall economic efficiency of bearing supports.
