Cross Tapered roller bearing Introduction
Cross Tapered roller bearing 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.
It is able to withstand high overturning moments, and is optimal for machine tools, including vertical boring, grinding machines, precision circular dividing table, gear hobbing machine turret and industrial robots.
Features
1. Precision crossed tapered roller bearings are intended for high Precision arrangements with combined axial-radial loads. A design of the bearing comprises an outer ring, split inner ring and tapered rollers in crossed position. the rollers are separated by plastic spacers. The concept of the bearing with tapered rollers in an x arrangement positioned in turns towards raceways enables to accommodate axial loads in both directions, radial loads as well as tilting moments.
2.In spite of a subtle cross section the bearings are characterized by considerable rigidity. as a result a single bearing can substitute a pair of bearings in a conventional arrangement. The tapered shape of rollers can effectively eliminate circumferential speed difference at rolling and prevent contact surfaces from skidding with further benefit of lower wearing the raceways and rollers. Ultimately a longer operational life of the bearing is achieved.lubrication of the bearings is enabled through a slot between inner rings.
3.The design of bearings assumes a fixed mounting of inner rings and rotating outer rings.the bearings are supplied unassembled after a final assembly the complete bearing adjusted with a preload ensures a clearancefree operation and high accuracy of running. the rings are manufactured from high quality steels heat treated to achieve a desired hardness. holes in the outer ring make handling, installation and fitting of the bearing into a machine easy
Design Features
The line contact of races and rollers can offer high rotation accuracy, high stability and high rigidity.
The adjustment design of pro-load extend the bearing using life, increase the rigidity and reach the smallest runout
The nylon spacers has low inertia and small running torque.
High rotation accuracy and high rigidity, and conserving material costs.
The steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.
