Tapered roller bearing cross reference XR496051 used for cnc machine|cross tapered roller bearing

XR496051 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.

Design Features
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 steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.

 Installation Procedure:

1.Thoroughly clean the housing and other parts to be installed, and check to determine if deburring is required.

2.Since the  cross tapered roller bearing  is a thin-wall bearing type and therefore tends to misalign when it is installed, in case of this situation,gradually drive the product into the housing or onto the shaft by gently hitting it with a plastic hammer, while keeping the product horizontal. Taking care, continue to hammer until it fully contacts the reference surface.

3.Place the presser flange onto the Crossed Roller bearing . Rock the flange several times to match the bolt holes.

4.Insert the presser bolts into the holes.  Manually turn the bolts and make sure they do not display skewing caused by misalignment of the holes.

5. As is shown in the pictures below:Tighten the presser bolts in three to four steps from light to full tightening byrepeatedly securing the bolts in diagonal order.When tightening the separable inner or outer ring, slightly turning the integral outer or inner ring will correct the dislocation between the ring and the body.

     Nowadays, as a professional percision bearing manufacture, we are proud of continual innovation, flexible production, speedy delivery, rapid after-sales service(2 years) and quick response.

       Luoyang BoYing Bearing Co., Ltd,(BYC) is a professional manufacturer of high precision bearings, which has combine researching and developing,producing and marketing together.
