Rolling element offers the best of both worlds

Rolling element offers the best of both worlds A hundred years after the ball bearing was invented and 50 years after the first needle roller bearing was produced, the Schaeffler Group has developed a totally new bearing concept, combining the best of both ball bearing and roller bearing technologies. The prototype 'ball roller' bearing incorporates bearing elements that are spherical, but which have their sides cut off. While the design may sound simplistic, the research and development behind this radical breakthrough has been significant. The result is a range of ball roller elements that offer all the axial load handling capabilities of fully spherical balls, but more importantly, allow overall bearing width and mass to be decreased by around 20 percent and friction to be reduced. Looked at another way, the breakthrough means that, in the same design space, it is possible to carry greater loads and provide a larger grease reservoir or more space for improved sealing.
