A centrifugal gas compressor radial magnetic bearing () may include windings (), a lamination sleeve (), and a lamination (). The lamination () aligned with the windings () may provide for efficient operation of the radial magnetic bearing (). The centrifugal gas compressor shaft () may include a tapered region () with an adjacent shelf () for alignment with the forward surface () and taper of the lamination sleeve (). The lamination sleeve () may include one or more axial hydraulic fitting ports () for coupling the lamination sleeve () and shaft () with an interference fit.

Lamination sleeve with an axial hydraulic fitting port

Radial magnetic bearings () of a centrifugal gas compressor () may lose power and fail to support the shaft () resulting in damage to the shaft (). Auxiliary bearings () may be used to support the shaft () during such a failure. A landing guard () may be installed as a sacrificial piece between the shaft () and the auxiliary bearings (). Landing guard () includes slots () that may be used with pins () in the shaft () to prevent an angular displacement between the landing guard () and the shaft ().
