Doubled life under same loads

Ideal for harsh operating environments, including construction machinery, rolling mills and lifting gear, new X-life axial spherical roller bearings from Schaeffler offer more than double the life under the same loads.
Launched at this year’s Hanover Fair, the X-life FAG E1 spherical roller thrust bearings now boast significant improvements, including increased load ratings (static +10%, dynamic +35%), limiting speeds (+50%) and fatigue limiting load (+70%). A revolutionary achievement is the bearing’s 170% increase in bearing rating life. These improvements make the bearing one of the best of its type on the market today.
The technical benefits are numerous: operating life has more than doubled under the same loads; similar operating life under significantly higher loads; suitable for high speed applications due to lower friction levels; improved guidance and vibration characteristics due to very high running accuracy; less wear due to optimised lubricant film formation; and the lubricant is subjected to less strain due to lower bearing temperatures.
For the customer, these benefits translate into higher machine availability, new design possibilities, more economical bearing supports due to downsizing; and lower operating costs due to reduced energy consumption.
Schaeffler’s axial spherical roller bearings are ideal for applications in which very high axial loads are present and where shaft deflections or misalignments of bearing seats must be compensated for. The bearings operate reliably in the harshest of environments, including gearboxes, calendars, marine and rudder engines, lifting gear, construction machinery and steel rolling mills.
