The company has launched a complete family of ball roller bearings that offers reduced friction and allows bearing mass and width to be decreased by 20%. The 'ball roller' is a new energy efficient range of bearings that utilises spherical bearing elements, but with their sides cut off. The result is a range of ball roller elements that offers all the axial load handling capabilities of fully spherical balls, but more importantly, allows overall bearing width and mass to be decreased by around 20%, as well as reducing friction. It means that in the same design space, it is now possible to carry greater loads and provide a larger grease reservoir or more space for improved sealing. In the new design, the manufacturer has removed all areas of a conventional rolling element 'ball' that are not under load. This means that 15% of the ball's diameter is cut off on both sides. The result is a flattened ball on both sides, which is 30% narrower than a conventional ball.
