Abstract
In the course of studying the market requirements for seals in large axles and relating this to conventional sealing technology, it became apparent that a fresh approach to sealing was desirable. This paper describes such a development in detail.
Centrifugal action is the principle sealing action of the seal. Although this is in itself not new, the method by which it is harnessed makes the design radically different from normal “slinger” seals. Both practical and analytical work are covered in the text.
