Abstract
A cartridge mount seal includes a unitary sleeve structure for telescopically receiving a seal ring adapter therein, the sleeve structure being sealed to a shaft and to the seal ring adapter. Automatic alignment of a stationary unit to the rotary unit is provided by way of an O-ring which slightly engages the outer surface of the sleeve during mounting of the stationary unit. The stationary unit includes a floating seal member for automatic alignment of the stationary and rotary seal faces. Distortion of the sleeve during clamping thereof to the shaft and centering of the sleeve are provided by a centering screw structure which radially sets the sleeve with respect to a reference surface on the stationary unit.
