JXR637050 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.

JXR637050 cross tapered roller bearing 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.

1. Industrial Neutral Packing,Package as your requirements.

2. Small size Bearings:Plastic vacuum packaging bag+Paper Box/Neutral Carton

3.Large size Bearings:Plastic film+Pergamyn paper+Roll tape+Wooden Box

4.Shipping:By air or By sea:DHL/TNT/UPS/EMS etc

 Installation Procedure:

1.Inspect the parts before installing:Clean bearing bracket,main axle or other parts to remove dirt or grease.

2.Place the bearing into the bearing bracket and main axle:To match the design clearance ,keep the bearing horizontal and insert the bearing into the bearing bracket or axle.If it is hard to install,use a rubber hammer to slightly hit every part of the bearing,so that the bearing can be attention to the hitting force is too large.Afterwards,the matching status of bearing and basic face can be examined by checking the noise.For a interference fit,use heating or cooling to expand or shrink the parts for ease of installation. Be sure the bearing temperature does not exceed 80℃ . If the split inner or outer ring is acentric, please loosen the blots slightly and rotate the monolithic ring to adjust the concentricity of split ring, so that the bearing can be fit in the bracket.

3.Install the mounting disc:Place the mounting disc onto the bearing and align the screw holes, Screw all the bolts in the holes first and follow the orders show in below diagram when tightening bolts in diagonally opposite sequence,Do not tighten bolts randomly.

Cautions:

1.The normal operating temperature of Crossed roller bearing is 10-80℃, If it is over this range,please contact BYC.

2.If a foreign substance enters inside the bearing structure, the rotation route of the roller may be damage, or the bearing may fail.Please clean the bearing by refill the lubricant grease.

3.Please do not remove or apply force to the bolt and nut of the split bearing.

     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.
