Abstract
An inner raceis retained by a crimped portionso that a pre-load is applied to rolling elementsA bearing unit for wheel supportis connected to a constant velocity jointthrough tightening of a nutBy regulating the tightening force of the nutat the area of contact between the inside end of the crimped portionand the outside end of the outer ring of the constant velocity jointthe load per unit length is controlled up to 125 N/mm, or the surface pressure is controlled up to 1.5×10Pa. Consequently, a bearing unit for wheel support is realized at a low cost with the pre-load securely applied, preventing unpleasant noise from occurring during operation, and preventing play due to plastic deformation.
