Abstract

A canned motor pump has a housing and a shaft which is mounted for rotation internally of the housing and extends between the pump and the motor. The end of the shaft remote from the pump is received by a plain bearing bushing. The bushing is press-fitted into a sleeve having a threaded section which serves to releasably connect the sleeve to the housing. The sleeve has another section which is adjacent to the threaded section and is provided with a conical surface. The conical surface cooperates with a complementary surface on the housing to center the sleeve.
