Patent ID: 8651496

Claim:
A seal to seal a gap between a rotatable component and a non-rotatable component, the rotatable component having an outer diameter, the seal comprising: a fastening section adapted to be fixedly mounted in relation to the non-rotatable component, a sleeve executed in metal and adapted to be mounted around the rotatable component such that the rotatable component is rotatable relative to the sleeve, the sleeve having an inner diameter defining a sealing surface, wherein the sealing surface forms a dynamic seal with the outer diameter of the rotatable component when the rotatable component is rotated, a resilient section disposed between the sleeve and the fastening section and including an arcuate portion, and wherein a ratio of the inner diameter of the sleeve in an unmounted state to the outer diameter of the rotatable component is greater than 1 such that a clearance fit is defined between the inner diameter of the sleeve and the outer diameter of the rotatable component, at least when the rotatable component is stationary.
