Design of associated components

It is advisable to provide support to the shields of bearings of the 2Z/VA228 and 2Z/VA208 design because of the axial guidance these provide for the graphite cage. Therefore, it is recommended that the housing shoulder or the bore diameter of the spacer sleeve should have a smaller diameter than the outer ring shoulder diameter D2 provided in the product table. If this is not possible a support washer with the appropriate bore diameter should be inserted between the bearing and housing shoulder or spacer sleeve (fig 1).
