Abstract
A seal system for a rotor assembly of a surface treatment machine includes a rotatable rotor assembly shell including surface treatment tools extending therefrom, and a stub-shaft located within the shell and fixedly coupled to the shell. The stub-shaft includes a shaft portion and a base portion, with the base portion including a recess. A non-rotatable bearing housing surrounds at least a portion of the shaft portion and has an longitudinally extending inner end located within the recess. A seal member is located in the recess and secured between the bearing housing and the base portion.
