HXR/JXR series Crossed Tapered Roller Bearings
Crossed tapered roller bearing contains double sets of raceways and rollers which are brought together at right angle with alternate rollers facing in opposite directions. Unlike crossed roller bearing, the rolling elements of Crossed tapered roller bearing are tapered rollers. The height of cross section is similar to single-row bearing, thus the design of bearing housing is simplified. The steep-angle tapered geometry makes the effective span of the bearing much greater than the width of the bearing itself. Crossed tapered roller bearings can carry high overturning moment, thus they are widely used in large hobbling machine, industrial robot, high speed vertical lathe, high precision working table, vertical boring machine, and spindle of grinding machine etc.
