Abstract
Abstract Radial and axial bearing devices in which loads are transmitted from a race through a series of circularly disposed rotating elements, and thence through a second series of rotating elements to a second race; the second series of rotating elements being generally roller-shaped and including ends which roll on retainer rings, the retainer rings being fastened to the first race.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
31 words
A rolling contact bearing comprising: a first bearing race, two retainer rings, said retainer rings being affixed to said first bearing race, a second bearing race, two series of rotating elements,
Claim 2
Dependent Claim
31 words
A rolling contact bearing comprising: a first bearing race, two retainer rings, said retainer rings being affixed to said first bearing race, a second bearing race, two series of rotating elements,
Claim 3
Dependent Claim
82 words
the first of said series of rotating elements contacting only said first bearing race and second said series of rotating elements, said second series of rotating elements serving to hold said first series of rotating elements in position against said first race, the rotating elements of said second series being generally roller-shaped, said second series of rotating elements being held in position against said first series by said retainer rings and being in contact only therewith and with said second bearing race.
Claim 4
Dependent Claim
82 words
the first of said series of rotating elements contacting only said first bearing race and second said series of rotating elements, said second series of rotating elements serving to hold said first series of rotating elements in position against said first race, the rotating elements of said second series being generally roller-shaped, said second series of rotating elements being held in position against said first series by said retainer rings and being in contact only therewith and with said second bearing race.
Claim 5
Dependent Claim
64 words
The rolling contact bearing as claimed in claim 1 in which the ratio of the diameter of the inner periphery of said first bearing race to the contact diameter of said retainer rings is equal to the ratio of the central diameter of said roller-shaped elements to the contact diameter of the ends of said roller-shaped elements, so as to assure rolling contact only.
Claim 6
Dependent Claim
19 words
The rolling contact bearing as claimed in claim 1 in which said first series of rotating elements comprises balls.
Claim 7
Dependent Claim
22 words
The rolling contact bearing as claimed in claim 1 in which said first series of rotating elements comprises generally roller-shaped rotating elements.
Claim 8
Dependent Claim
32 words
The rolling contact bearing as claimed in claim 1 in which said first bearing race is located radially outwards of said second bearing race, so as to describe a radial load bearing.
Claim 9
Dependent Claim
43 words
The rolling contact bearing as claimed in claim 1 in which said first bearing race is located radially outwards of said second bearing race and is also axially displaced from same, so as to describe a combination radial load and axial load bearing.
Claim 10
Dependent Claim
41 words
The rolling contact bearing as claimed in claim 1 in which at least one of said retainer rings is affixed to said first bearing race by screw threads, so as to provide means of adjusting the internal clearance in said bearing.
