XR/JXR series of Cross Tapered Roller Bearings contains two sets of races and rollers brought together at high angles with alternate rollers facing in opposite directions .The height of cross section is similar to single-row bearing for conserving space and saving bearing housing material. And the steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself. Cross tapered roller bearings can withstand higher overturning moment, suitable for machine tools, including vertical boring machine, grinding machine bench, precision circular dividing table, large hobbing machine, rotary table, industrial robot, etc.
