An improved and enhanced dynamic seal for use in high-speed turbomachinery includes an inner ring coupled to an outer sleeve. The coupling between the inner ring and the outer sleeve is strengthened by forming an increased surface area, exhibited by recesses, in at least one of the outer surface of the inner ring and the inner surface of the outer sleeve, and by providing an adhesive material in the recesses to bond the inner ring to the outer sleeve. Additionally, the coupling can be further strengthened by providing complementary projections on at least one of the outer surface of the inner ring and the inner surface of the outer sleeve to fit into the recesses.
