XR496051|crossed Taper Roller Bearings|203.2*279.4*31.75mm
The XR496051 bearing is a crossed taper roller bearings with an inner diameter of 203.2 mm , an outer diameter of 279.4 mm, a width of 31.75 mm. It typically uses P2/P4 grade precision tolerances and no seals type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
XR496051 Crossed taper 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 singlerow 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.XR496051is 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.

Design Features of XR496051
l The line contact of races and rollers can offer high rotation accuracy, high stability and high rigidity.
l The adjustment design of pro-load extend the bearing using life , increase the rigidity and reach the smallest runout.
l The nylon spacers has low inertia and small running torque.
l High rotation accuracy and high rigidity , and conserving material costs.
l The steepangle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.
