Abstract
Abstract A pump shaft is journaled in a housing through the intermediary of two metal rings forming the outer races of a ball bearing and a roller bearing whose rotary bodies are in direct contact with the shaft. The two bearing rings, which are relatively axially shiftable during assembly, are interconnected by a sleeve preferably of synthetic resin which they engage with a snap fit. The outer diameter of the sleeve is less than that of either ring; the two outer ring diameters may also differ in size from each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
A journal mounting for a shaft rotatable inside a housing, comprising: a first and a second bearing ring axially spaced from each other, said bearing rings concentrically surrounding said shaft and being separated by annular clearances from respective peripheral zones thereof; a first set of rotary bodies partly received in an inner annular groove of said first bearing ring in a confronting annular groove of said shaft at one of said peripheral zones; a second set of rotary bodies inserted between said second bearing ring and said shaft in contact with the other of said peripheral zones; and a sleeve between said bearing rings having extremities snap-fitted onto same.
Claim 2
Dependent Claim
109 words
A journal mounting for a shaft rotatable inside a housing, comprising: a first and a second bearing ring axially spaced from each other, said bearing rings concentrically surrounding said shaft and being separated by annular clearances from respective peripheral zones thereof; a first set of rotary bodies partly received in an inner annular groove of said first bearing ring in a confronting annular groove of said shaft at one of said peripheral zones; a second set of rotary bodies inserted between said second bearing ring and said shaft in contact with the other of said peripheral zones; and a sleeve between said bearing rings having extremities snap-fitted onto same.
