Abstract
Abstract A method for the manufacture of bearings, of the type in which rolling members are retained between two pairs of races. A cage constituted by two pairs of races and intermediate rolling members is placed within a mould which has two wedge like elements. As the mould is closed these two elements expand the cage radially outward. Plastics material is then injected into the mould on either side of the cage to encase same.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
74 words
A method of manufacture of bearings in which rolling members are retained between two pairs of independent metal races submerged in two annular masses of moulded synthetic plastics material said method including the steps of; placing inside a moulding cavity a cage constituted by two pairs of races and intermediate rolling members, closing the said cavity, expanding the said cage radially outwardly and injecting synthetic plastics material on either side of the said cage.
Claim 2
Independent Claim
74 words
A method of manufacture of bearings in which rolling members are retained between two pairs of independent metal races submerged in two annular masses of moulded synthetic plastics material said method including the steps of; placing inside a moulding cavity a cage constituted by two pairs of races and intermediate rolling members, closing the said cavity, expanding the said cage radially outwardly and injecting synthetic plastics material on either side of the said cage.
Claim 3
Dependent Claim
24 words
A method as claimed in claim 1, in which the radial expansion of the cage is obtained during the closure of the moulding cavity.
