Abstract
Spray assemblies for use in coating a regular or irregular internal surface of a cylinder, and methods for coating the inside of a cylinder are disclosed. The spray assemblies may include: a spray head comprising a nozzle for spraying a coating material on an internal surface of a cylinder; a support wand coupled to the spray head; and a roller sleeve rotatably connected to the support wand and configured to contact the internal surface of the cylinder and to rotate radially as the cylinder is rotated. The spray assemblies may be used to provide a consistent and repeatable coating thickness, regardless of cylinder internal diameter. In some embodiments, the spray assemblies may be used to coat the internal surface of a stator tube.
