Abstract
A shaft seal comprises a rotatable seal ring carrying an annular seal member for rotatably engaging a seal face of a seal member. The seal ring is mounted in a seal holder and is coupled for rotation with a hollow sleeve connected to the shaft by at least one drive pin extending radially inwardly from the seal holder and received in a longitudinal peripheral groove, in the hollow sleeve, terminated by an annular groove. The drive pin and the longitudinal groove have flat sides and the annular groove provides for milling of the longitudinal groove with a cylindrical tool without leaving arcuate terminating sides on the longitudinal groove and permits positioning of the seal interface as close as possible to the drive mechanism.
