Claim Text:
1. A lamination sleeve of a radial magnetic bearing for a shaft of a centrifugal gas compressor, comprising: an outer surface; an inner surface located radially inward from the outer surface, the inner surface configured to contact the shaft when the lamination sleeve is installed on the shaft; a forward surface located at an axially forward end of the lamination sleeve; an aft surface located at an axially aft end of the lamination sleeve; the outer surface, the inner surface, the forward surface, and the aft surface forming an elongated tubular shape; a slot formed in the inner surface and oriented to extend circumferentially adjacent the shaft at least half of the circumference of the inner surface; a hydraulic fitting port for receiving a fitting tool that injects hydraulic fluid into the slot during installation of the lamination sleeve to hydraulically fit the lamination sleeve onto the shaft, the hydraulic fitting port extending from the forward surface into the elongated tubular shape; a passageway extending from the hydraulic fitting port to the slot, wherein the passageway is in flow communication with the hydraulic fitting port and the slot; and a seal located at the inner surface adjacent the aft surface.
