Abstract
A spindle assembly for use with a rotating member is provided. The spindle assembly may include a flexible shield or seal that, in one embodiment, is radially and axially secured to one end of a spindle shaft of the assembly. The seal may be spaced-apart from one or more bearings rotationally supporting the shaft. As a result, a space between the seal and the bearing may be provided that allows dissipation of energy from a fluid (e.g., pressurized stream of cleaning fluid) that is forced past the seal. Moreover, spindle assembly constructions in accordance with embodiments of the instant invention may permit increased bearing spacing, potentially reducing bearing load and increasing bearing life.
