Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
A recirculating antifriction bearing comprising an elongated cylindrical race body, a plurality of roller members each having an annular radial concave recess centrally thereof, said cylindrical race body and said concave recess having the same radius of curvature for providing roller engagement therebetween, said race body being floatingly mounted on said roller members for providing infinite adjustability of said race body about its axial center line, return member means partially enclosing at least the ends of said race body and being spaced therefrom for defining a raceway therebetween, and side member means extending along said race body on opposite sides of said return member means and fixed relative to said return member means.
Claim 2
Dependent Claim
113 words
A recirculating antifriction bearing comprising an elongated cylindrical race body, a plurality of roller members each having an annular radial concave recess centrally thereof, said cylindrical race body and said concave recess having the same radius of curvature for providing roller engagement therebetween, said race body being floatingly mounted on said roller members for providing infinite adjustability of said race body about its axial center line, return member means partially enclosing at least the ends of said race body and being spaced therefrom for defining a raceway therebetween, and side member means extending along said race body on opposite sides of said return member means and fixed relative to said return member means.
Claim 3
Dependent Claim
25 words
A bearing as defined in claim 1 wherein said return member means have a width slightly greater than the axial length of said roller members.
Claim 4
Dependent Claim
62 words
A bearing as defined in claim 1 wherein said side member means include a pair of flat plates each having an elongated hole portion, said flat plates being disposed parallel to each other on opposite sides of an axial center line of said race body, and said race body extending outwardly through the elongated hole portion in each of said flat plates.
Claim 5
Dependent Claim
19 words
A bearing as defined in claim 4 wherein said cylindrical race body includes hemispherical portions at each end thereof.
Claim 6
Dependent Claim
89 words
A recirculating antifriction bearing comprising an elongated cylindrical race body, a plurality of roller members each having an annular radial concave recess centrally thereof, said cylindrical race body and said concave recess having the same radius of curvature for providing rolling engagement therebetween, said race body being floatingly mounted on said roller members for providing infinite adjustability of said race body about its axial center line, and return member means partially enclosing at least the ends of said race body and being spaced therefrom for defining a raceway therebetween.
Claim 7
Dependent Claim
89 words
A recirculating antifriction bearing comprising an elongated cylindrical race body, a plurality of roller members each having an annular radial concave recess centrally thereof, said cylindrical race body and said concave recess having the same radius of curvature for providing rolling engagement therebetween, said race body being floatingly mounted on said roller members for providing infinite adjustability of said race body about its axial center line, and return member means partially enclosing at least the ends of said race body and being spaced therefrom for defining a raceway therebetween.
