Detailed description

XR855053 Crossed taper roller bearing|NC lathe bearing|685.8*914.4*79.38mm

XR855053 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 steepangle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself. XR855053 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.

Design Features of XR855053 crossed taper roller bearings

l The line contact of races and rollers can offer high rotation accuracy, high stability and high rigidity.

l The adjustment design of proload 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 steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.
