two support ring segments 15 will match the annular groove inside diameter 24 as it will exist after the plurality of fasteners 14 have been fully tightened this allows full support of the load bearing portion of the outer race 2 during operation of the cylindrical roller bearing a under heavy loads it will be appreciated however that other embodiments of the present invention may utilize holes in the support ring 12 which are not through holes and still remain within the scope of the dimension in such an embodiment the holes may be tapped blind holes to allow the use of threaded fasteners to attach the support ring 12 to the outer race 2 in other embodiments other types of fasteners may also be used in yet other embodiments the outer race 2 may simply be clamped in such a manner as to compress the flanges 22 as needed to deform the outer raceway 10 from its initial arcuate shape to the final generally cylindrical shape in fact any type of mechanism may be used as long as the support ring 12 is secured to the outer race 2 and allows for the uniform deformation of the outer race 2 as described herein to effect a preload on the internal components of the cylindrical roller bearing a one possible way to assemble this particular embodiment of the cylindrical roller bearing a is to position the two support segments 15 within the annular groove 13 of the outer race 2 and loosely install the plurality of fasteners 14 into the holes 16 a of.
