Abstract
The propensity for gas leakage around a shaft, which connects volumes of differing pressures, in, e.g., a turbocharger is minimized in a simple cost-effective manner. The addition of a complementary pair of frusto-spherical, conical, or other profiles to the interface of the shaft and its bearing maintain concentricity of the shaft in its bore and thus improve the efficacy of existing sealing protocols.
