Influence of Hydrodynamics on the Performance of Radial Lip Seals

Depending on the lubricating condition of a radial lip seal, there are different mechanisms of sealing and wear. An empirical theory on the mechanism of friction and the performance of radial lip seals has been established by experimental investigations. Hydrodynamic laws similar to those used it the theory of journal bearings may be used to describe the mechanism of friction, wear and seal-performance. This theory has been successfully used to explain some otherwise controversial test results as consequences of different lubricating conditions.

Oil Seal Quality Control—Important or Imperative

In 1957, a research program was initiated for the study of radial lip seals. Results of this study indicated that there was a lack of seal technology concerning the seal lip characteristics and a lack of equipment to measure various design parameters necessary to good sealing practice. From a program of planned experimentation, there emerged a series of controls which, when put into practice, resulted in vastly improved seals being available for assembly and an inherent reduction in the sealing problems.
