The WK bearing is essentially a “king size” W bearing that features a ball / ball internal design. Standard dimensions consist of a 1.5000″ outer ring diameter and a 2.125″ outer ring length. The standard shaft diameter size is 3/4″. Larger rolling elements and envelope dimensions allow for higher load carrying ability. This bearing is typically used in automotive water pump applications. Some special designs are available that allow this bearing family to be used in many other applications.
