Lip seals are widely used tribological machine elements with applications in manufacturing, oil, gas, aerospace, transport, and power industries. Their function is to separate fluids between two regions that share a common moving boundary. This paper sets out to investigate in detail the impact of operating a seal in various states of misalignment. A sophisticated seal test apparatus, compliant with ISO 6194-1:1982 has been developed. It allows precise states of misalignment between the shaft and seal centres to be set and enables the measurement of a range of variables including friction torque, leakage rate and temperature to characterise the performance of the seal. The paper will present measurements of these parameters as a function of speed and shaft eccentricity and discuss the implications of this data on the operating limits of seals.
