ABSTRACT:
A mechanical face seal including a non-rotable member fixed to a container and a rotatable member fixed to a shaft. The rotatable member includes a laminated holder constructed of press-fitted, metallic bands, and a non-metallic insert press-fitted in the holder. The outer band is in tension and the inner band in compression upon assembly of the holder so that the stresses in these parts tend to balance one another. Upon assembly of the insert to the holder, the inner band may be in tension.
