The design of every bearing has been optimized to provide the user with the most efficient and dependable product possible. Years of experience have shown the need for a proper balance between rolling element diameter and raceway thickness, Roller length and the flange and cage ring thickness, and the number of rollers or balls and the thickness of the cage web separating the elements. Such a balanced design gives the user high load carrying capacity without jeopardizing the strength of the individual bearing components. However, more goes into an AMERICAN roller bearing than a balanced design. Execution of the design is what makes the product excellent, and the following discussion describes the various components that make up our line of industrial bearings.
