The HVL style may be described as a very light duty HV style ring. It is often characteristic of this ring to not have a circular shape in free state. This ring is generally used as a bearing mount where bearings are required to 'float' axially.
The Tolerance Ring allows a simple consistent joint of cylindrical parts using dissimilar materials without the complications and cost of adhesive, secondary machining operations or machined details, such as splines or threads. The Tolerance Ring sits between the two components resulting in an engineered fastening.
When mounting a bearing, the Tolerance Ring sits between the application housing and the outer face of the bearing. The wave forms of the Tolerance Ring acts as springs generating a controlled retention force between the outer face of the bearing and application housing.
