Abstract
An alignment apparatus includes a first stator, located in a stator of a piece of rotating equipment, and a second stator couplingly connected to the first stator and able to be angularly rotated relative to the first stator. The second stator can seal an interface between a shaft and housing in the piece of rotating equipment. The alignment apparatus permits angular misalignment between a stator, a housing and a rotor shaft, and may be used, for example, in a bearing protector or an isolator installed on a Pillow Box.
