摘要： A roller bearing assembly for use in a fracking pump crank shaft includes an inner ring being positioned an outer ring and a plurality of rolling elements disposed therebetween. Each of the rolling elements have a bore extending therein. The roller bearing assembly includes a cage having an annular disc with pins extending axially inward therefrom and into the bore. The pins are positioned on the annular disc so that the rolling elements are spaced apart from one another with a gap extending continuously therebetween. The gap is of a predetermined magnitude to maximize the number of rolling elements that fit between the inner ring and the outer ring to maximize load carrying capacity of the roller bearing assembly.
